Absorption and Fluorescent Studies of 3-Hydroxychromones.

Abstract

The synthesis and spectral studies of variously substituted 3-hydroxychromones have been carried out. A key relationship between the structural motif of synthesized 3-hydroxychromones (3-HCs) and their fluorescent properties was found. The chromones substituted with electron-donating group at 4'-position expressed the red shift of the N(*) and T(*) band and also exhibited the increased fluorescent intensity ratio while the chromones with electron-withdrawing group showed the blue shift of the N(*) and T(*) band. Therefore, these 3-HCs may behave as the possible fluorescent probes.
