A systematic comparison of the physical properties and the dual-role (host and electron transport) applications of star-shaped 1,3,5-triazine-based ET-type hosts (T2T, 3N-T2T, 3P-T2T, and oCF3-T2T) with differential peripheral groups was reported. The introduction of N-heterocyclic polar peripheries onto a 1,3,5-triazine core gave evident benefits to the electron injection/transport properties, rendering efficient PhOLEDs with a simpler device configuration feasible. Among these hosts, 3P-T2T can serve both as a promising host and electron-transport material for various Ir-based electrophosphorescence devices. These PhOLEDs configured with the same device structure exhibited low operation voltages with a maximum ηext of 8%, 15.7%, 16.9%, 16.4% and 10.8% for sky blue (FIrpic), green [(PPy)2Ir(acac)], yellow [(Bt)2Ir(acac)], red [(Mpq)2Ir(acac)] and white [FIrpic + 0.5 wt%(Mpq)2Ir(acac)], respectively.

Tris-pyrazolyl-1,3,5-triazines have been prepared by cyclotrimerization of aromatic nitriles in solvent-free conditions. The interesting structures of these compounds make them candidates for application in coordination chemistry and crystal engineering.
