Doubly ortho-linked quinoxaline/triarylamine hybrid as a bifunctional, dipolar electroluminescent template for optoelectronic applications

The titled hybrid (Q-H) works as a clippable optoelectronic unit. Q-spacer-Q systems function as efficient orange emitters reaching EL intensities (L) of up to 6840 cd m^–2 with (eta)ext of 0.77% and operation efficiencies of 1.60 cd A^–1 and 0.8 lm W^–1. Notably, Q-An acts as a (bluish) green emitter, reaching L of 12347 cd m^–2 with similar operational efficiency.
