Phen-TRZ has a structure of phenoxazine directly attached to diphenyltrazine with spacer in between. Comparing with PXZ-TRZ, Phen-TRZ is relatively sterically hindered without the rotational degree of freedom.
Phen-TRZ is a light blue TADF emitter and can replace PXZ-TRZ for a blue shade of green emission.
