Reverse saturable absorbing cationic iridium(<scp>iii</scp>) complexes bearing the 2-(2-quinolinyl)quinoxaline ligand: effects of different cyclometalating ligands on linear and nonlinear absorption

Abstract

Iridium(<sc>iii</sc>) complexes bearing the 2-(2-quinolinyl)quinoxaline ligand absorb weakly at 450–750 nm and can be used as broadband reverse saturable absorbers.
