Abstract High ambipolar mobility emissive conjugated polymers (HAME‐CPs) are perfect candidates for organic optoelectronic devices, such as polymer light emitting transistors. However, due to intrinsic trade‐off relationship between high and strong solid‐state luminescence, the development of HAME‐CPs suffers from structural synthetic complexity. Herein, a universal design principle simple approach developed. A series non‐fused composed charge transfer units, π bridges units synthesized via two‐step microwave assisted C−H arylation direct polymerization protocol with total yields up 61 %. The is verified valid among 7 monomers 8 polymers. Most importantly, all have emission photoluminescence quantum 24 Furthermore, 4 exhibit field effect 10 −2 cm 2 V −1 s , can be used in multifunctional devices. This work opens new avenue developing by efficient synthesis rational design.
