摘要: Abstract Novel linear and star branched triphenylamine-containing aromatic imides were designed synthesized by the condensation between amine-substituted triphenylamine naphthalene-1, 4, 5, 8-tetra-carboxylic dianhydride in order to investigate influence of topological structure on photophysical performance. The polyimides characterized elementary analysis FTIR measurements. Thermogravimetric (TGA) shows that onset temperatures decomposition ( T d ) for 5% mass loss range from 371 445 °C. UV-Vis spectrum, quantum chemical calculation cyclic voltammetry (CV) used obtain dependence energy levels function structures. introduction group changes level entire dye system. dye-sensitized solar cells (DSSCs) prepared using dyes have a strong photoelectric current response visible light region 400–600 nm.
