A hybridized local and charge transfer excited state for solution-processed non-doped green electroluminescence based on oligo(-phenyleneethynylene)

We herein report a new highly efficient green emissive hot-exciton molecule, 1,4-bis((4′-diphenylamino-3-cyano-[1,1′-biphenyl]-4-yl)ethynyl)-2,5-bis(2-ethylhexyloxy)benzene ( 2EHO-TPA-CNPE ) that consists of an extended D′-π′-A-π-D-π-A-π′-D′ molecular π-system with diphenylamino end units (D′) and e...
