摘要：

A new iridium(III) complex based on the triazole-pyridine ligand with tetrathiafulvalene unit, [ Ir(ppy)(2)(L)] PF6 (1), has been synthesized and structurally characterized. The absorption spectra, luminescent spectra and electrochemical behaviors of L and 1 have been investigated. Complex 1 is found to be emissive at room temperature with maxima at 481 and 510 nm. The broad and structured emission bands are suggested a mixing of (LC)-L-3 ((3)pi-pi*) and (CT)-C-3 ((MLCT)-M-3) excited states. The influence of iridium ion coordination on the redox properties of the TTF has also been investigated by cyclic voltammetry.
