| abstract |
The present invention relates to coumarin-like green light dyes containing triphenylamine ethylene side chains, the green light dyes have the structure shown in formula (I), wherein R1, R2 and R3 are independently represented as hydrogen, C1-C8 substitution or unsubstituted alkyl, alkoxy or halogen. The test of its photophysical properties shows that the molecule represented by formula (1) has high fluorescence quantum yield, and has good application potential in green light conversion film materials. The material has strong luminescence, is not sensitive to the preparation process, and its emission spectrum is very stable in a large doping concentration and temperature range. |
