- Abstract:
- A series of donor-π-acceptor(D-π-A)compounds involving varied donors and acceptors as well as a dihydroquinolinone moiety were synthesized.Tuned fluorescent colors from blue to orange were successfully realized in them.Spectroscopic analysis exhibits that the increased conjugated system, enhanced electron-donating ability of acceptor, and electron-withdrawing ability of donor result in red shift in both absorption and fluorescence for these compounds.Both the absorption and fluorescence show strong bathochromic shift effect with the increase in the polarity of solvents.It indicates that they are intramolecular charge transfer(ICT)fluorescent compounds and may have potential application as novel electroluminescent material.
