Abstract
A novel full-functional photorefractive small molecular material,(9-ethyl-9H-carbazol-3-ylmethylene)-(4-nitro-phenyl)-amine (ECYENPA),was synthesized and its photorefractivity was studied by two-beamcoupling experiments at a wavelength of 632.8 nm. The glass transitiontemperature of ECYENPA, as low as −5 degrees C, results in thechromophore being orientated easily at room temperature. High two-beamcoupling coefficient was obtained to be 232 cm−1 at an electricfield of 44.6 V/μm.
