摘要

Two novel triethylene-glycol dicoumarin-3-carboxylates were synthesized and characterized by element analysis, 1H NMR, FT-IR and UV–vis absorption spectra. The photoluminescent behaviors of triethylene-glycol dibenzo [5, 6] coumarin-3-carboxylate doped in PMMA were discussed. These compounds exhibit strong blue emission under ultraviolet light excitation. Compared to coumarin-3-triethylene glycol diester, the absorption and emission spectra of ...
