Synthetic strategies for organic electronic materials based on thiophene, pyrrole and fluorene assemblies

This project focuses on new techniques and ideas to engineer the polymer materials and their monomer precursor of bilayer organic light emitting diodes devices (OLED) in such a way as to control the boundary region between the two layers and thereby improve charge balance and radiative efficiency. This is addressed by synthesis of the electron transport layer (ETL) and hole transport layer (HTL) precursors bearing hydrogen bonding and mesogenic functionalities. Hydrogen bonding at the interface ensures a well-defined boundary region whilst the mesogenic groups impart some structural regularity to the films resulting in good conjugation length and charge mobility.
