TpOx-n-Bu

TpOx-n-Bu is a UV excitable fluorescent material with a polycyclic aromatic donor-acceptor structure where the triphenoxazole core acts as a donor and the butyl group on the two position of the oxazole as the acceptor group. TpOx-n-Bu is also a photo-conducting Discotic Liquid Crystalline (DLC) material with mesophase transition onset temperature of 90°C. TpOx-n-Bu is designed for 355 nm excitation with emission at 366 nm with quantum yield of 0.16, high thermal, chemical and photostability. TpOx-n-Bu has potential uses in fluorescent dye staining, organic electronic and photonic applications.

TpOx-n-Bu can be purchased from Sigma Aldrich website.
