Synthesis and Optical Properties of a Polyyne Dendrimer
摘要
Abstract
A polyyne dendrimer (PD) was synthesized in four-steps and characterized by 1H NMR, 13C NMR, MS, FT-IR, etc. Subsequently, ultraviolet visible (UV-Vis) absorption spectra and fluorescence spectra were further investigated in a series of solvents, in which obvious aggregation-induced emission (AIE) were observed. In addition, the electrochemiluminescence (ECL)properties in solid state were also investigated. Interestingly, the π-extended PD with slight distorted configuration possessed intense and stable cathodic ECL emission, which indicatedthat it has potential application in the future construction of high-performance ECL emitters.
