1,3,5-Tri(9-carbazolyl)benzene (TCB)(CAT: M098723) is a high-performance organic semiconductor widely used as a hole-transport and host material in optoelectronic devices. Its rigid benzene core, substituted with three carbazolyl groups, imparts excellent thermal stability, strong charge-transport properties, and efficient energy-level alignment. TCB is frequently employed in organic light-emitting diodes (OLEDs), where it serves as a host for blue and phosphorescent emitters, improving device efficiency and operational lifetime. Its strong film-forming capability and balanced charge mobility also make it valuable in organic photovoltaics and other thin-film applications. Combining stability, versatility, and performance, TCB remains an essential material in advanced display and electronic technologies.
