Preparation and Nonlinear Optical Property of Triazole-Based Fluorene Functional Polymer

The controllable preparation of nonlinear optical polymers is still one of the research hotspots on nonlinear optical field. In this paper, a triazole functional polymer was designed and achieved by high-efficiency click chemistry method. The structure and properties of the polymer was characterized and evaluated with FTIR, NMR, UV, FL, DLLS and nonlinear optical analyses. The results exhibited that the polymer was successfully synthesized and has favorable nonlinear optical property, its third-order nonlinearity up to 3.66×10-10esu.
