Synthesis and Luminescence Behavior of a Novel Charge Transfer Compound Containing Carbazole Phenylhydrazone
Abstract:
A novel compound,containing a strong electron donor and a strong electron acceptor,3-((2-(2,4-dinitrophenyl) hydrazono) methyl)-9-ethyl-9H-carbazole,was synthesized. Its spectral property and photophysical behavior were studied. Intermolecular charge transfer occurred from N-ethylcarbazole to NO2-with the increase of the solvent polarity. Double fluorescence emission was observed in strong polarity solvent. Change of dipole moment between the ground state and the excitation state was 4.53 D. Dimmer or polymer was formed at high concentration and the emission wavelength was red shifted.
