The article conveys some information:

Naphthalene diimide (NDI)-based polymer N2200 is a promising organic polymer acceptor for all-polymer solar cells (all-PSCs), but its inherent shortcomings like poor extinction coefficient and strong aggregation limit further performance optimization of all-PSCs. Here, a series of random copolymers, PNDI-Px, were designed and synthesized by introducing porphyrin unit into NDI-based polymer as acceptors for all-PSCs. These random copolymers show a higher absorption coefficient and raised the LUMO (LUMO) energy levels compared to N2200. The crystallinity can also be fine-tuned by regulation of the content of porphyrin unit. The random copolymers are matched with polymer donor PBDB-T for the application in all-polymer solar cells. The best power conversion efficiency (PCE) of these PNDI-Px-based devices is 5.93%, ascribed to the overall enhanced device parameters compared with the N2200-based device. These results indicate that introducing porphyrin unit into polymer is a useful way to fine-tune the photoelec. performance for efficient all-PSCs.

In 2022,Yin, Chao; Tai, Xiaoyan; Li, Xiaozhen; Tan, Jihua; Lee, Chun-Sing; Sun, Pengfei; Fan, Quli; Huang, Wei published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《Side chain engineering of semiconducting polymers for improved NIR-II fluorescence imaging and photothermal therapy》.HPLC of Formula: 51364-51-3 The author mentioned the following in the article:

Development of efficient agents for NIR-II fluorescence imaging (NIR-II FI) offers opportunities to facilitate NIR-II FI in biomedicine and life science. Although semiconducting polymers (SPs) are proved to be excellent candidates for NIR-II FI, their fluorescence quantum yields are generally low mainly because of the accelerated nonradiative decay by the vibrational overlap between the ground state and excited state due to the small energy gap of NIR-II SPs. We herein propose a side chain engineering of SPs for enhanced NIR-II FI and imaging-guided photothermal therapy (PTT). The fluorescence optimization is realized by tuning the conformation and bulk of side chains of SPs, which demonstrates that the bulky branched side chains remarkably contribute to the fluorescence enhancement relative to linear or short branched side chains. D. functional theory (DFT) calculation indicates that bulky branched side chain-attached SP (P3) has the largest dihedral angle between electron donor and acceptor units, which suggests the largest intramol. steric hindrance that restricts the free rotation in the mol., thus boosting the radiative decay to generate fluorescence. Water-dispersible nanoparticles with high tumor specificity fabricated from the optimal P3 are employed for in vivo applications, which show excellent NIR-II FI performance and PTT efficacy toward tumor. Our study therefore proposes a feasible mol. guideline to amplify the NIR-II brightness of SPs for improved phototheranostics. In the experiment, the researchers used many compounds, for example, Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3HPLC of Formula: 51364-51-3)

Formula: C51H42O3Pd2In 2020 ,《Near-Infrared Absorptive and Emissive Poly(p-phenylene vinylene) Derivative Containing Azobenzene-Boron Complexes》 appeared in Macromolecules (Washington, DC, United States). The author of the article were Wakabayashi, Junko; Gon, Masayuki; Tanaka, Kazuo; Chujo, Yoshiki. The article conveys some information:

Poly(p-phenylene vinylene) (PPV) is known to be a typical π-conjugated polymer and used as a commodity platform for constructing optoelectronic organic devices because of superior optical and material properties. PPV derivatives generally show a large degree of light absorption and intense emission in the visible region; meanwhile, very few examples have been reported to offer near-IR (NIR) absorptive and emissive PPV derivatives In this study, we designed and synthesized a novel PPV derivative, named BAz-PPV, containing boron-fused N=N double bond units in the main chain. BAz-PPV showed intense NIR absorption and emission (λabs = 702 nm, λPL = 760 nm, and ΦPL = 2.0% in diluted toluene). This polymer had a narrow energy band gap because of not only extension of main chain π-conjugation over 50 monomer units but also stabilization of the energy level of the LUMO. Moreover, the polymer shows high stability toward photodegradation and sufficient carrier-transport ability for the applications in organic semiconducting devices. Advantages of the introduction of the N=N double bond to main-chain conjugation followed by boron coordination for the development of NIR materials are demonstrated in this manuscript. The experimental part of the paper was very detailed, including the reaction process of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Formula: C51H42O3Pd2)

Ye, Shaofeng; Wang, Yaxiong; Guo, Runda; Zhang, Qing; Lv, Xialei; Duan, Yalei; Leng, Panpan; Sun, Shuaiqiang; Wang, Lei published their research in Chemical Engineering Journal (Amsterdam, Netherlands) on August 1 ,2020. The article was titled 《Asymmetric anthracene derivatives as multifunctional electronic materials for constructing simplified and efficient non-doped homogeneous deep blue fluorescent OLEDs》.Formula: C18H14BrOP The article contains the following contents:

Large π-conjugated core anthracene with an innate bipolar property was used to construct multifunctional organic electronic materials. Delicate manipulating mols. via combining anthracene core and large periphery groups, 2 asym. anthracene derivatives (4-(10-(4-(9H-1,5-diazacarbazol-9-yl)phenyl)anthracen-9-yl)phenyl)diphenylphosphine oxide (p-PO15NCzDPA) and (3-(10-(3-(9H-1,5-diazarcarbazol-9-yl)phenyl)anthracen-9-yl)phenyl)diphenylphosphine oxide (m-PO15NCzDPA) were firstly designed and developed. The large periphery groups 1,5-diazarcarbazole (15NCz) and diphenylphosphine oxide (PO) efficiently interrupt the intramol. π-conjugation, presenting an asym. bulky periphery enveloping strategy achieving highly twisted structures, which help to realize deep-blue emission. Due to the high PLQY and well-balanced bipolar transport characteristics, desired device addressing the contradiction of efficiency, color gamut and structure complexity is within reach. Detailed device engineering study was carried out, in which p-PO15NCzDPA and m-PO15NCzDPA were functioned as multifunction layers. As expected, p-PO15NCzDPA-based homogeneous and unilateral homogeneous OLEDs exhibited outstanding performance with impressive EQEmax of 4.55 and 6.40%, deep blue CIE coordinates of (0.152, 0.075) and (0.151, 0.066) at the voltage of 6 V, narrow FWHM of 46 nm and 50 nm, resp. The simplified homogeneous device achieved extremely low efficiency roll-offs of 1.3 and 4.8% at 1000 and 5000 cd m-2, resp. These results are among the most outstanding performance, which provided a guide for further improving the performance of deep blue fluorescent OLEDs and simplifying the structure of OLEDs.

In 2022,Iqbal, Rashid; Ali, Sajjad; Yasin, Ghulam; Ibraheem, Shumaila; Tabish, Mohammad; Hamza, Mathar; Chen, Henan; Xu, Hu; Zeng, Jie; Zhao, Wei published an article in Chemical Engineering Journal (Amsterdam, Netherlands). The title of the article was 《A novel 2D Co3(HADQ)2 metal-organic framework as a highly active and stable electrocatalyst for acidic oxygen reduction》.Application of 51364-51-3 The author mentioned the following in the article:

Efficient and robust electrocatalysts for acidic Oxygen reduction reaction (ORR) is crucial for the proton exchange membrane hydrogen fuel cells. However, the current electrocatalysts suffer from the stability issues in the acidic environment during ORR. Herein, we introduce a new layer-stacked two-dimensional (2D) metal-organic framework (MOF), Co3(HADQ)2 (HADQ = 2,3,6,7,10,11-hexaamine dipyrazino quinoxaline), synthesized for the first time. This novel MOF material shows the extremely high conductivity of 8,385.744 S/m with extraordinary activity (E1/2 = 0.836 V vs. RHE, n = 3.93, and jL = 5.31 mAcm-2) and an exceptional stability (up to 20,000 cycles) as the electrocatalyst for ORR in an acidic media (pH = 0.29), outperforming most of the state of the art Metal-N-C and single-atom electrocatalysts for acidic ORR. D. functional theory calculations indicate that the Co-sites are the active sites. We propose that Co3(HADQ)2 is a promising model catalyst for mechanistic studies of acidic ORR, due to its well defined and tunable structure.

《Imide-functionalized acceptor-acceptor copolymers as efficient electron transport layers for high-performance perovskite solar cells》 was written by Shi, Yongqiang; Chen, Wei; Wu, Ziang; Wang, Yang; Sun, Weipeng; Yang, Kun; Tang, Yumin; Woo, Han Young; Zhou, Ming; Djurisic, Aleksandra B.; He, Zhubing; Guo, Xugang. Related Products of 51364-51-3 And the article was included in Journal of Materials Chemistry A: Materials for Energy and Sustainability in 2020. The article conveys some information:

Electron transport layers (ETLs) are critical for improving device performance and stability of perovskite solar cells (PVSCs). Herein, a distannylated electron-deficient bithiophene imide (BTI-Tin) is synthesized, which enables us to access structurally novel acceptor-acceptor (A-A) type polymers. Polymerizing BTI-Tin with dibrominated naphthalene diimide (NDI-Br) and perylene diimide (PDI-Br) affords two A-A copolymers P(BTI-NDI) and P(BTI-PDI). The all-acceptor backbone yields both low-lying HOMO (HOMO) and LUMO (LUMO) energy levels for the polymers, which combined with their high electron mobility render P(BTI-NDI) and P(BTI-PDI) as promising ETLs for perovskite solar cells (PVSCs). When applied as ETLs to replace the conventional [6,6]-phenyl-C61-butyric acid Me ester (PC61BM) in planar p-i-n PVSCs, the PC61BM-free devices based on P(BTI-NDI) and P(BTI-PDI) achieve remarkable power conversion efficiencies (PCEs) of 19.5% and 20.8%, resp., with negligible hysteresis. Such performance is attributed to efficient electron extraction and reduced charge recombination. Moreover, the devices based on P(BTI-NDI) and P(BTI-PDI) ETLs show improved stability compared to the PC61BM based ones due to the higher hydrophobicity of the new ETLs. This work provides important guidelines for designing n-type polymers to replace PC61BM as efficient ETLs for high-performance PVSCs with improved stability. The results came from multiple reactions, including the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Related Products of 51364-51-3)
