一般說明
TpOx-Ph-p-CF3 is a UV excitable fluorescent material with a polycyclic aromatic donor-acceptor structure where the triphenoxazole core acts as a donor and the aromatic group on the two position of the oxazole (4-trifluoromethyl-phenyl) act as the acceptor group. The push-pull, donor-acceptor, structure facilitates intramolecular charge transfer in the excited state that results in a 255 nm emission Stokes Shift. This oxazole is also a photo-conducting Discotic Liquid Crystalline (DLC) material with mesophase transition onset temperature of 145 °C. It is designed for 355 nm and 405 nm excitation with emission at 526 nm with quantum yield of 0.51, high thermal, chemical and photostability. This luminescent compound has potential uses in fluorescent dye staining, organic electronic and photonics, and imaging applications.
