Reference of Tris(dibenzylideneacetone)dipalladium(0)In 2020 ,《Molecularly engineered thienyl-triphenylamine substituted zinc phthalocyanine as dopant free hole transporting materials in perovskite solar cells》 was published in Sustainable Energy & Fuels. The article was written by Huang, Peng; Hernandez, Adrian; Kazim, Samrana; Ortiz, Javier; Sastre-Santos, Angela; Ahmad, Shahzada. The article contains the following contents:

To ensure the success of perovskite solar cells (PSCs), developing dopant-free hole transporting materials is of paramount importance to induce long-term stability. Phthalocyanines have emerged as a viable alternative to the common Spiro-OMeTAD, due to their excellent optoelec. properties and chem. stability. We report the design and semiconducting properties of a thienyl-triphenylamine tetrasubstituted zinc(II) phthalocyanine, and its application in PSCs. The PSCs fabricated with zinc phthalocyanine without the use of any dopant and additives gave a competitive power conversion efficiency in excess of 14.5%, along with long-term stability. In the experiment, the researchers used many compounds, for example, Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Reference of Tris(dibenzylideneacetone)dipalladium(0))

In 2019,Synthetic Communications included an article by Ohtsuka, Yuhki; Hagiwara, Hideki; Miyazaki, Takanori; Yamakawa, Tetsu. Recommanded Product: Tris(dibenzylideneacetone)dipalladium(0). The article was titled 《Palladium-Catalysed Amination of Hindered Aryl Halides with 9H-Carbazole》. The information in the text is summarized as follows:

Palladium-catalyzed Buchwald-Hartwig amination of ortho-substituted hindered aryl bromides or chlorides RX (R = 2-tolyl, 1,1′-biphenyl-2-yl, naphth-1-yl, naphthalen-1-ylphenyl; X = Br, Cl) with 9H-carbazole has been investigated. In the amination of 1-bromo- or chloronaphthalene with 9H-carbazole, the combined use of Pd2(dba)3 as a Pd precursor, Buchwald ligands with two tert-Bu groups and LiOtBu or lithium hexamethyldisilazide as a base led to satisfactory yields. N,N’-Bis[2,6-bis(diphenylmethyl)-4-methoxyphenyl]imidazol-2-ylidene (IPr*OMe), which is a bulky N-heterocyclic carbene ligand, showed similar activity as Buchwald ligands with two tert-Bu groups. In contrast, only IPr*OMe provided satisfactory yields in the amination of 2-bromo-1,1′-biphenyl with 9H-carbazole. The amination of 2-bromo- or chlorotoluene and 1-(2-bromo- or chlorophenyl)naphthalene with 9H-carbazole proceeded smoothly when the IPr*OMe ligand was used. The results came from multiple reactions, including the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Recommanded Product: Tris(dibenzylideneacetone)dipalladium(0))

In 2019,Advanced Optical Materials included an article by Meng, Guoyun; Chen, Xing; Wang, Xiang; Wang, Nan; Peng, Tai; Wang, Suning. Computed Properties of C51H42O3Pd2. The article was titled 《Isomeric Bright Sky-Blue TADF Emitters Based on Bisacridine Decorated DBNA: Impact of Donor Locations on Luminescent and Electroluminescent Properties》. The information in the text is summarized as follows:

Three isomeric boron-containing thermally activated delayed fluorescent (TADF) emitters, namely m-AC-DBNA, p-AC-DBNA, and m’-AC-DBNA, are constructed by incorporating an electron-donor acridine (AC) moiety into meta-, para-, or meta’-positions of an electron-accepting boron-embedded rigid framework. The substitutional positions are found to dramatically affect thermal, photophys., and electroluminescent (EL) properties. The exptl. results show that the para-substituted compound (p-AC-DBNA) exhibits higher decomposition temperature, higher photoluminescence (PL) quantum efficiencies, smaller singlet-triplet energy splitting, shorter delayed fluorescence lifetimes as well as a fast reverse intersystem crossing rate of over 106 s-1, compared to the meta-isomers (m-AC-DBNA and m’-AC-DBNA). Bright and highly efficient organic light-emitting diodes (OLEDs) with external quantum efficiencies (EQEs) up to 20.5% and 14.1% are achieved by employing p-AC-DBNA as doped and nondoped emitters in sky-blue OLEDs, resp. Moreover, excellent doping-concentration independent EL properties and very low efficiency roll-off at a high luminance are achieved. This isomeric strategy provides a simple method to extend structural diversity of highly efficient TADF emitters, optimize optoelectronic properties, and demonstrate the relationship of delayed fluorescence lifetime and efficiency roll-off of the TADF devices. The three isomers also display distinct temperature-dependent emission and mechanochromism. In the experiment, the researchers used Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Computed Properties of C51H42O3Pd2)
