TpOx-Ph-m-CF3 is a UV excitable fluorescent dye 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 (3-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 232 nm emission Stokes Shift. TpOx-Ph-m-CF3 is also a photo-conducting Discotic Liquid Crystalline (DLC) material with mesophase transition onset temperature of 132°C. TpOx-Ph-m-CF3 is designed for 355 nm and 405 nm excitation with emission at 503 nm with quantum yield of 0.48, high thermal, chemical and photostability. TpOx-Ph-m-CF3 has potential uses in fluorescent dye staining, organic electronic and photonics, and imaging applications.
