The mononuclear Mn bis-terpyridine complex [Mn(tolyl-terpy)2](X)3 (1(X)3; X = BF4, ClO4, PF6; tolyl-terpy = 4′-(4-methylphenyl)-2,2′:6′,2”-terpyridine), containing Mn in the unusual +III oxidation state, was isolated and characterized. The 13+ ion is a rare example of a mononuclear MnIII complex stabilized solely by neutral N ligands. Complex 13+ is obtained by electrochem. oxidation of the corresponding MnII compound 12+ in anhydrous MeCN. Under these conditions the cyclic voltammogram of 12+ exhibits not only the known MnII/MnIII oxidation at E1/2 = +0.91 V vs. Ag/Ag+ (+1.21 V vs. SCE) but also a 2nd metal-based oxidation process corresponding to MnIII/MnIV at E1/2 = +1.63 V (+1.93 V vs. SCE). Single crystals of 1(PF6)3·2MeCN were obtained by an electrocrystn. procedure. X-ray anal. unambiguously revealed its tetragonally compressed octahedral geometry and high-spin character. The electronic properties of 13+ were studied in detail by magnetic measurements and theor. calculations, from which a D value of +4.82 cm-1 was precisely determined D. functional and complete active space SCF ab initio calculations both correctly predict a pos. sign of D, in agreement with the compressed tetragonal distortion observed in the x-ray structure of 1(PF6)3·2MeCN. The different contributions to D were calculated, and (1) the spin-orbit coupling part (+2.593 cm-1) is predominant compared to the spin-spin interaction (+1.075 cm-1) and (2) the excited triplet states make the dominant contribution to the total D value.

Author is Yamamoto, Kyoko; Yoshikawa, Ryoko; Okuyama, Shigeru; Takahashi, Yuki; Karasawa, Yasuko; Hino, Noriko; Miyoshi, Toshio; Araki, Hiroaki; Hanabusa, Kenji.

We have identified 4′-(4-methylphenyl)-2,2′:6′,2-terpyridine trihydrochloride (SS701), which belongs to a family of a small unique neuroprotective agents. SS701 accelerated the production of nerve growth factor (NGF) in cultured astroglial cells, dose- and time-dependently. In in vivo studies, SS701, when administered 30 min after induced cerebral ischemia, neuroprotective effects on delayed neuronal death in Mongolian gerbils were evident. The neuroprotective effects of SS701 against ischemia-induced delayed neuronal death are attributed to stimulation of the production of NGF.

Category: catalyst-ligand. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Synthesis, Structure, Photophysical Properties, and Redox Behavior of Cyclometalated Complexes of Iridium(III) with Functionalized 2,2′-Bipyridines. Author is Neve, Francesco; Crispini, Alessandra; Campagna, Sebastiano; Serroni, Scolastica.

The new functionalized polypyridine ligands 4′-(4-chlorophenyl)-6′-phenyl-2,2′-bipyridine (clpbpy), 4′-(4-tolyl)-6′-phenyl-2,2′-bipyridine (tpbpy), and 4′-(4-carboxyphenyl)-6′-phenyl-2,2′-bipyridine (cpbpy), together with the known 4′-(4-hydroxyphenyl)-6′-phenyl-2,2′-bipyridine (hpbpy) and 4′-(4-tolyl)-2,2′:6′,2”-terpyridine (ttpy) have been used to prepare a new series of Ir(III) cyclometalated compounds [Ir(ppy)2(HL-X)][PF6] (ppy is the monoanion of 2-phenylpyridine; HL-X = hpbpy (1), clpbpy (2), tpbpy (3), cpbpy (4), and ttpy (5)). All the new species have been characterized by IR and 1H NMR, and the crystal structure of 4 is also presented and discussed. All the metal complexes exhibit oxidation mainly centered on an orbital derived from an Ir-(C-) σ-bond and ligand-centered reduction processes; all of them are luminescent from 3MLCT levels both at 77 K in a rigid matrix and at 298 K in fluid solution The redox and absorption properties are more or less insensitive to the remote substituents on the rotationally free 4′-Ph ring, whereas fine-tuning of the luminescence properties is observed on changing substituents. The results show that the “”energy gap law”” for radiationless decay in the weak coupling limit is obeyed by this series of complexes, when complex 5 is excluded. Interestingly, the slope of the linear relationship between ln knr and the emission energy at room temperature is significantly smoother than that reported for other luminescent polypyridine complexes containing different metals. Because of the high luminescence quantum yield and the presence of functionalities in the polypyridine ligand framework, the complexes reported may be considered as useful building blocks for light- and redox-active, multicomponent supramol. systems.

Compound: 4-(p-Tolyl)-2,2:6,2-terpyridine, is researched, Molecular C22H17N3, CAS is 89972-77-0, about Proton-Activated Amorphous Room-Temperature Phosphorescence for Humidity Sensing and High-Level Data Encryption. Author is Deng, Yuchen; Li, Peng; Sun, Shujuan; Jiang, Haiyan; Ji, Xu; Li, Huanrong.

Supramol. co-assembling terpyridine-derivatives I and II, with nanoclay (LP) are exploited to acquire efficient amorphous room-temperature phosphorescence (RTP). Exptl. and theor. investigations reveal that this co-assembly not only brings about a configuration transformation from the trans-trans (a) to the cis-trans (a”) form via the protonating process, significantly narrowing the singlet-triplet energy gap, thereby effectively facilitating the single-triplet ISC processes, but also well protects the triplet state and suppresses the nonradiative transitions via restricting mol. rotation and vibration by the hydrogen-bond interactions between them. Addnl., the flexible and transparent films, through co-assembling 1@LP (or 2@LP) with polyvinyl alc. (PVA), also display excellent phosphorescence performance. Owing to their distinctive RTP performances, the RH sensing and high-level data encryption are achieved.
