Title:
COUMARIN GREEN LIGHT DYE CONTAINING TRIPHENYLAMINE ETHYLENE SIDE CHAIN
Document Type and Number:
WIPO Patent Application WO/2018/120971
Kind Code:
A1
Abstract:
Provided is a coumarin green light dye containing a triphenylamine ethylene side chain. The green light dye has a structure shown in formula (I), wherein R1, R2 and R3 independently represent hydrogen, a C1-C8 substituted or unsubstituted alkyl, alkoxyl or halogen. A molecule having a structure shown in formula (I) has a high fluorescent quantum yield and has a good application potential with regard to light conversion film materials using green light. The material has a strong light-emitting property, is not sensitive to a preparation process and has a very stable emission spectrum in relatively large doping concentration and temperature ranges.
