Microwave Synthesis And Photophysical Characterization Of Heteroleptic Iridium Complexes For Applications In Oleds And Lecs, Allyson Dixon
Seton Hall University Dissertations and Theses (ETDs)
A series of heteroleptic, iridium-based ionic transition metal complexes (ir-iTMCS), with the purpose to serve as potential components of OLED and LEC devices, were synthesized through a green, combinatorial-based approach. This work utilized a microwave reactor in order to bring our research into closer alignment with the tenets of green chemistry. The aim of this research was to assess the effects of structural differences, specifically steric crowding, on the photophysical characteristics of the complexes. The radiative quantum efficiencies (Φf) and excited state lifetimes (τ ) of the series of Ir-iTMCs were investigated. The rates of radiative (kr …
