2,4,6-Tris[3-(diphenylphosphinyl)phenyl]-1,3,5-triazine Chemical Properties,Uses,Production

Description

PO-T2T, namely2,4,6-tris[3-(diphenylphosphinyl)phenyl]-1,3,5-triazineis electron deficient with a triazine centre and three diphenylphosphines.

Uses

PO-T2T is an electron transport/hole blocking material in OLED, or an electron acceptor material in organic electronics.

An efficient action of radical-based OLEDs, whose emission originates from a spin doublet, rather than a singlet or triplet exciton was demonstrated in a study published in Nature.
While the emission process is still spin-allowed in these OLEDs, the efficiency limitations imposed by triplet excitons are circumvented for doublets. Using a luminescent radical emitter, an OLED with maximum external quantum efficiency of 27% at a wavelength of 710nm-the highest reported value for deep-red and infrared LEDs was achieved. In this very efficient OLEDs, selective hole injection into the HOMO and electron injection to the SOMO was achieved imploying TAPC as the hole transport layer, and PO-T2T as the electron transport layer to form the fluorescent doublet excited state with near-unity internal quantum efficiency.
