39.1: Solution Processed Molecular Materials in the Fabrication of Flexible Phosphorescence‐based OLEDs

Abstract

OLEDs were fabricated by solution process, particularly, having amorphous small molecule SimCP2 as the host material for blue phosphorescence dopant FIrpic. Having SimCP2 as a whole or part of host materials, solution processed flexible OLEDs (2 × 2 cm on ITO-coated PET) exhibit blue electrophosphorescence with CIE x,y coordinates of (0.22, 0.29) and current efficiency as high as 23 and 19 cd/A at 100 and 1000 cd/m 2 , respectively, has been achieved.
