Fluorescent host for blue, green and red light emitting active layer materials

High purity (>99% sublimed) mCPBC in quantities from 100 mg to 1 g


mCPCB, 9-(3-(9H-carbazol-9-yl)phenyl)-9H-3,9'-bicarbazole, has a structure of carbazole and 3-9'-bicarbazole attached to a phenyl ring at meta-positions.

Having three conjugated carbazolyl units and a wide band gap, mCPCB is electron rich and it is normally used as fluorescent host for blue, green and red light emitting active layer materials. Like mCP and SimCP, mCPCB is a hole transport dominating host with low polarity. mCPCB has been proven a great match as the host material to DABNA dopant derivatives for highly efficient blue emitting TADF devices.
