Diarylmaleimide Fluorophores: Intensely Emissive Low-Band-gap Guest for Single White Polymers with Highly Efficient Electroluminescence

Intensely emissive diarylmaleimides PM and TM were introduced into the backbone of polyfluorene (PF) to obtain single white polymers, PFPM and PFTM. PFPM showed highly efficient and white electroluminescence for effective energy transfer from the PF host to the maleimide guest.
