Properties of Charge Transfer Complex Based on Triphenylene Molecule
摘要
In this paper, 2,3-diethylester-6,7,10,11-tetrapentaloxy-triphenylene (23TPE) as electron donor and 2,4,7-trinitro-9-fluorenone (TNF) as electron acceptor were designed and synthesized, and their molecular structures were confirmed by infrared spectroscopy (FT-IR) and nuclear magnetic hydrogen spectroscopy (1H-NMR). Product 23TPE/TNF was obtained by evenly mixing 23TPE and TNF at molar ratio 1:1. Infrared spectroscopy (FT-IR) and ultraviolet visible spectroscopy (UV-vis) were used to study its spectral characteristics. Polarizing microscope (POM) and differential scanning calorimeter (DSC) were used to investigate the liquid crystal properties. The experimental results showed that 23TPE/TNF doping formed a charge transfer complex (CTC).
