DMAC-BP, green TADF emitter

High-purity (>99.0%) and available online for priority dispatch


DMAC-BP, bis[4-(9,9-dimethyl-9,10-dihydroacridine)phenyl]methanone is better known as a green Thermally Activated Delayed Fluorescence (TADF) emitter.

Due to the short conjugation length of the DMAC and BP group, a higher energy of the lowest locally-excited triplet state (3LE) is achieved. This energy is almost equal to that of the triplet charge-transfer state (3CT). The difference of the lowest singlet and triplet excited states ΔEST is 0.07 eV [2].

Compared to mCP-doped films, neat films of DMAC–BP have a slightly red-shifted emission band with a maximum of 506 nm, a slightly lower photoluminescence quantum yield (PLQY) of 0.85, and TADF lifetime of 2.7 μs.
