Hu, Fang published the artcileThe photocyclization-dependent ratiometric fluorescent switch: Synthesis, characterization and properties of some terpyridyl-based dithienylethenes, Computed Properties of 219537-97-0, the publication is Dyes and Pigments (2017), 161-167, database is CAplus.
Some terpyridyl-based dithienylethenes were synthesized and their structures were confirmed by NMR spectroscopy, mass spectroscopy and elemental anal. The photochromic properties and fluorescence behaviors of these compounds have been measured upon irradiation with UV or visible light in solution UV/vis absorption spectra and fluorescence spectra indicated that the dithienylethenes displayed obvious photochromism and fluorescent switch properties. Specially, when compared with other terpyridyl-based dithienylethenes, the triphenylamine and terpyridyl-based dithienylethene showed the photocyclization-dependent ratiometric fluorescent switch behaviors. D. functional theory indicated that the photocyclization-dependent ratiometric fluorescent changes were due to the donor-acceptor system of the switch.
