Photoalignment and spatial patterning of liquid crystalline conjugated polymers for polarised light emission

Thesis

Polymeric semiconductors have a number of benefits in the ease of processing and large-area production, tunability of the physical properties, low-cost, flexibility and biocompatibility. Although high-quality polymer alignment is highly favorable in terms of allowing access to fundamental optical/electrical anisotropy, the realisation of large-area extended uniform alignment and high-resolution spatial patterning of polymer chain-orientation remains a challenge. The purpose of this thes...
