文摘

Series of 1,3-indandione and dimedone dyes with amino substituents are synthesized. Structure-properties relationship is analyzed through different methods. Dyes emission color and quantum yields are dependent on used amino donor structure. Dyes with diphenylamino and biphenylamino donors shows high quantum yields. π-spacer length has significant impact on optical and electrochemical properties.
