Synthesis and Characterization of Model Compounds For Self-Assembled Dithienophosphole-Based Phosphamides

Abstract

On the path to synthesizing classes of dithienophosphole soft materials, this thesis documents the synthesis and characterization of model compounds for self-assembled dithienophosphole-based phosphinamides. Expanding upon the blue-emitting series within this class of compounds and targeting applications in white OLEDs, green and orange emitters, along with their corresponding model compounds, are reported. Taking advantage of the ease of functionalizing the α-position of the dithienophosphole core, the emitter compounds were synthesized via Suzuki cross-coupling reactions. The model compounds, incorporating hydrogen-bonding moieties, were prepared through substitution at the phosphorus center. Comprehensive characterization was performed, including optical and spectroscopic analyses, and full synthetic details are provided.
