Stereoregular tetraphenylethene derivatives ( Z )‐ o ‐BCaPTPE and ( Z )‐ o ‐BTPATPE featured with chiasmatic conformations and aggregation‐enhanced emission characteristics are synthesized using a McMurry reaction. Both luminogens exhibit high hole and electron mobilities. Organic light‐emitting diodes (OLEDs) using ( Z )‐ o ‐BCaPTPE and ( Z )‐ o ‐BTPATPE as both the light‐emitting and electron‐transporting layers show high efficiencies.
