Abstract

A novel naphthalimide dimer tethered by photochtomic bisthienylethene-bridge was syhthesized by Suzuki coupling method as potentially all photo-mode memory media and fluorescent molecular switch. Bisthienylethene-bridged naphthalimide (BTE-NP) dimer reversibly changed the fluorescence intensity by alterative irradiation with ultraviolet and green visible light probably due to the fluorescence resonance energy transfer (FRET) from naphthalimides to the closed form of bisthienylethene moiety. All compounds were characterized by ¹H NMR spectra and mass spectra etc. The spectroscopic properties including the fluorescence lifetime and photochromic quantum yields of BTE-NP were also measured.
