Preparation of a tetraphenylethylene-based emitter: synthesis, structure and optoelectronic properties of tetrakis(pentaphenylphenyl)ethylene.
Soluble tetrakis(pentaphenylphenyl)ethylene (1), prepared in three steps, allows non-emissive tetraphenylethylene (TPE) to turn into an emitter (Phi(F) = 0.13) owing to the steric bulk of the four large hexaphenylbenzene propellers which hamper =C-Ph and C=C bond rotations in the TPE core.
