And solid-emissive materials can be built up by non-covalent intermolecular interaction. In this work, solid-emissive BODIPY dye with electron-donating group was synthesized for discussion of structure-property relationship. Structure of the synthesized compounds has been characterized by UV-vis, 1H NMR, and MS measurement. The photophysical property of the BF2 chelate was studied in different solvents and concentrations. Modified BODIPY fluorescent dyes can be widely applied to analytical chemistry, biochemistry, medicine, clinical diagnosis, environmental s
