TpOx-p-BiPh

TpOx-p-BiPh 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-phenyl-phenyl) act as the acceptor group. The push-pull, donor-acceptor, structure facilitates intramolecular charge transfer in the excited state that results in a 220 nm emission Stokes Shift. TpOx-p-BiPh is also a photo-conducting Discotic Liquid Crystalline (DLC) material with mesophase transition onset temperature of 123°C. TpOx-p-BiPh is designed for 355 nm and 405 nm excitation with emission at 490 nm with quantum yield of 0.61, high thermal, chemical and photostability. TpOx-p-BiPh has potential uses in fluorescent dye staining, organic electronic and photonics, and imaging applications.
