英文摘要: The design and synthesis of multifunctional molecular materials has recently attracted numberous of research attentions in the field of chemistry and material chemistry.In this project, we explored to synthesis a series of multifunctional molecular materials with the white light and liquid crystals properties;these compounds contain the double emission centers ligands of bluish-green fluorescence,an Eu3+ moiety as the origin of red light and auxiliary ligands with long alkyl and alkoxy chains.This objective can be achieved by changing the molecular structure of the ligands, controling the light intensity of the different light-emitting unit and the packing structure of compounds.The structure as well as luminesence, liquid crystal and thermodynamic properties of the target compounds will be investigated to establish structure-property correlation.We will further selecete some compounds with coupling between white light and liquid crystal properties as the research system, of these compounds, the preparation method of muitifunctional liquid crystal film and liquid crystal texture and fluoresence properties of thin film activated by electric field and light will be explored.The goal of this project is to improve the film-forming performance of single component white light complexes, as well as provide solutions
