Abstract
This thesis details the synthesis and characterization of new azaheterocycle containing non-fullerene
acceptors for use in organic photovoltaics (OPV). Herein, we present two independent studies where
azaheterocycles serve different uses. Chapter one introduces non-fullerene acceptors including current
limitations in the field and the different azaheterocycles to be used within this work. Chapter two goes over
the computational studies undertaken prior to synthetic work to confirm the validity of synthetic targets.
Chapter three details the design, synthesis, and characterization of two fused electron acceptors using bis trifluoromethyl naphthyridine as an endcap. These molecules were implemented in devices via our
collaborator Dr. Greg Welch where devices gave a performance of around 0.1% PCE. Chapter four includes
the design, synthesis, and characterization of three new non-fused electron acceptors using
diazaheterocycles as the central unit to influence morphology and the effects from different isomer
conformation. All final compounds were further characterized via UV-vis spectroscopy and cyclic
voltammetry.
