An overview of LC polyazomethines with aliphatic–aromatic moieties: Thermal, optical, electrical and photovoltaic properties

In this review, liquid crystalline (LC) polyazomethines (PAZs) with aliphatic–aromatic moieties were investigated, taking into consideration their thermal, structural, optical and electrical properties. Liquid crystalline polymers with imine bonds in the main or side chains were analysed. The optical properties of LC polyazomethines, including UV–vis absorption, photoluminescence (PL) and thermoluminescence (TL), were studied, taking into consideration the polymer structure. Finally, the electrical properties, including the photovoltaic properties of a bulk heterojunction (BHJ) and monolayer devices based on LC polyazomethines, were investigated and compared with PAZ, which did not exhibit LC properties. In this review article, the recent research trend on LC polyazomethines is summarised.
