Ionic iridium complex coordinated with tetrathiafulvalene-fused phenanthroline ligand: Synthesis, photophysical, electrochemical and electrochemiluminescence properties

A new cationic iridium(III) complex salt, [Ir(ppy)(2)(L)]PF6 (ppy = 2-phenylpyridine) (1), was synthesized by using tetrathiafulvalene fused 4',5'-dimethyldithiotetrathiafulvenyl[4,5-f][1,10]phenanthroline (L) as (NN)-N-boolean AND ancillary ligand. The photophysical, electrochemical and electrochemiluminescence (ECL) behavior of the complex are investigated. Complex 1 is found to be emissive at room temperature with the lambda(max) value at 607 nm. It is expected that this new luminescent complex 1 would be further explored for promising applications in functional emitting material. (C) 2013 Elsevier B. V. All rights reserved.
