Abstract A series of bis‐cyclometalated iridium(III) complexes, [Ir(LH) 2 (H dcbpy)][PF 6 ] ( 1 ), [Ir(LMe) and [Ir(LPh) 3 where LH = 1‐H‐2‐phenylbenzimidazole, LMe 1‐methyl‐2‐phenylbenzimidazole, LPh 1,2‐diphenylbenzimidazole, H dcbpy 2,2′‐bipyridine‐4,4′‐dicarboxylic acid, has been synthesized fully characterized by elemental analysis, 31 P NMR spectroscopy, mass spectrometry, single‐crystal X‐ray analysis. The complexes show strong luminescence in the yellow–orange region ethanol at room...
Cyclometalation of 2-arylbenzimidazoles decorated with various polyaromatic fragments leads to formation strongly absorbing iridium dyes applicable in DSSC and enables access structurally diverse iridium( iii ) complexes.
Cyclometalated Ru(ii) complexes with 2-arylbenzimidazole antenna ligands bearing electron-donor/withdrawing substituents and anchoring 4,4'-dimethoxycarbonyl-2,2'-bipyridine have been prepared their structure, optical electrochemical properties studied. The possess enhanced light-harvesting characteristics compared to those of the standard N719 dye absorb light up 750 nm. In addition, they demonstrate reversible redox behavior Ru3+/Ru2+ potentials being finely tuned by change...
New donor–π–acceptor pyrimidine-based dyes comprising an amide moiety as anchoring group have been designed. The were synthesized by sequential procedures based on the microwave-assisted Suzuki cross-coupling and bromination reactions. influence of dye structure length π-linker photophysical electrochemical properties photovoltaic effectiveness dye-sensitized solar cells was investigated. An increase in efficiency with a decrease revealed. D1 only one 2,5-thienylene-linker provided highest...
Though 2-arylperimidines have never been used in iridium(III) chemistry, the present study on structural, electronic and optical properties of N-unsubstituted N-methylated 2-(2-thienyl)perimidines, supported by DFT/TDDFT calculations, has shown that these ligands are promising candidates for construction light-harvesting complexes. In contrast to N-H perimidine, ligand gave expected cyclometalated μ-chloro-bridged dimer which was readily converted a cationic heteroleptic complex with...
The development of novel materials with improved functional characteristics for supercapacitor electrodes is current concern and calls elaboration innovative approaches. We report on an eco-friendly enzymatic synthesis a composite based poly(3,4-ethylenedioxythiophene) (PEDOT) multi-walled carbon nanotubes (MWCNTs). redox active compound, sodium 1,2-naphthoquinone-4-sulfonate (NQS), was used as dopant the backbone polymer. Oxidative polymerization 3,4-ethylenedioxythiophene (EDOT) catalyzed...
