Luminescent biscyclometalated arylpyridine iridium(iii) complexes with 4,4′-bi-1,2,3-triazolyl ancillary ligands

Luminescent biscyclometalated arylpyridine iridium(III) complexes with 4,4'-bi-1,2,3-triazolyl ancillary ligands.

The synthesis, characterization and photophysical investigation of complexes of the form [Ir(R-ppy)2(btz)]PF6 (1 to 3) are reported (btz = 1,1'-dibenzyl-4,4'-bi-1,2,3-triazolyl, R-ppy = 4-(pyrid-2-yl)benzaldehyde (1), 2-phenylpyridine (2) and 2-(2,4-difluorophenyl)pyridine (3)). Complexes 1, 2 and 3 are luminescent and exhibit structured emission bands with vibronic progressions at 532 & 568 nm...

Study on Sensing Systems Based on Luminescent Biscyclometalated Iridium(III) Complexes

New alkylzinc complexes with bulky tris(triazolyl)borate ligands: surprising water stability and reactivity.

Bulky alkylzinc complexes, (Ttz(tBu,Me))ZnMe and (Ttz(tBu,Me))ZnEt, show remarkable stability towards water and both complexes crystallize with one molecule of adventitious water hydrogen bonded to two triazole rings; in contrast the less bulky complex, (Ttz(Ph,Me))ZnEt, reacts with water to yield (Ttz(Ph,Me))(2)Zn.

Pyridine imines as ligands in luminescent iridium complexes.

Biscyclometallated iridium complexes [Ir(ppz)2(X^Y)][PF6] (X^Y = pyridine imine) have been synthesised. The pyridineimine ligands are prepared in situ during the complexation. The complexes show room temperature emission between 640 and 780 nm in CH2Cl2 solution. The emission is red shifted compared with the analogous bipyridine complex [Ir(ppz)2(bipy)][PF6]. DFT calculations have been used to ...

Luminescent platinum complexes containing phosphorus-linked silole ligands.

A series of Pt(ii) complexes containing silole-based ligands with diphenylphosphino groups terminally bound to a conjugated organic linker unit coordinated to the silole ring in the 2- or 2,5-positions, 1,1-dimethyl-2-(5'-diphenylphosphino-2'-thienyl)-3,4-diphenylsilole (4), 1,1-dimethyl-2,5-bis(5'-diphenylphosphino-2'-thienyl)-3,4-diphenylsilole (5), and 1,1-dimethyl-2,5-bis(4'-diphenylphosphi...
