TpOx-Ph-p-Me

TpOx-Ph-p-Me 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-methyl-phenyl) act as the acceptor group. The push-pull, donor-acceptor, structure facilitates intramolecular charge transfer in the excited state that results in a 185 nm emission Stokes Shift. TpOx-Ph-p-Me is also a photo-conducting Discotic Liquid Crystalline (DLC) material with mesophase transition onset temperature of 107°C. TpOx-Ph-p-Me is designed for 355 nm excitation with emission at 455 nm with quantum yield of 0.54, high thermal, chemical and photostability. TpOx-Ph-p-Me has potential uses in fluorescent dye staining, organic electronic and photonics, and imaging applications.
