Abstract

Transition metal complexes are utilized in a broad array of applications such as photoredox catalysis, photodynamic therapy, biological sensing, and as phosphors for organic light-emitting diodes. Furthermore, many transition metals complexes demonstrate two photon absorption and reverse saturable absorption (RSA) characteristics increasing their applications as non-linear optical materials. Iridium is of particular interest to our work because of its strong spin-orbit coupling, which allows for multiple excited states, thereby increasing the compound’s ability to absorb light over a broad spectrum. This work describes the synthesis of a series of triphenylamine and methoxy functionalized 2-phenylbenzo[d]thiazole (pbt) ligands to explore the effects on the photophysical properties of the synthesized Ir(III) cyclometalated chromophores and evaluate their potential application as RSA materials.
