Description

This carbonyl-bridged coumarin dimer features two electron-rich diethylamino-substituted chromenone units linked by a central carbonyl group, enabling efficient intramolecular energy transfer. The extended π-conjugation delivers strong fluorescence with high quantum yield, while the sterically shielded structure enhances photostability under prolonged irradiation. Designed for use in organic light-emitting materials and fluorescent sensors, this compound offers excellent solubility in common aprotic solvents and maintains stability under standard bench conditions.

Application

3,3'-Carbonylbis(7-(diethylamino)-2H-chromen-2-one) serves as a versatile bis-fluorescent chromophore scaffold, enabling efficient construction of extended π-conjugated systems. Its rigid, planar structure and electron-rich diethylamino groups facilitate strong intramolecular charge transfer, making it valuable for dye synthesis and materials applications. The compound exhibits good bench stability and facilitates straightforward purification, supporting scalable use in organic synthesis and functional material development.
