TpOx-Ph-opo-3F

<p align=”justify”>TpOx-Ph-opo-3F is UV excited 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 (2,4,6-trifluoro-phenyl) act as the acceptor group. The push-pull, donor-acceptor, structure facilitates intramolecular charge transfer in the excited state that results in a 226 nm emission Stokes Shift. TpOx-Ph-opo-3F is also a photo-conducting Discotic Liquid Crystalline (DLC) material with mesophase transition onset temperature of 105°C. TpOx-Ph-opo-F is designed for 355 nm and 405 nm excitation with emission at 496 nm with quantum yield of 0.63, high thermal, chemical and photostability. TpOx-Ph-opo-3F has potential uses in fluorescent dye staining, organic electronic and photonics, and imaging applications.</p>
