Integration of aggregation-induced emission and delayed fluorescence into electronic donor–acceptor conjugates†
A series of luminogens comprised electron donors and acceptors are found to possess two types of interesting photophysical processes of aggregation-induced emission (AIE) and delayed fluorescence. According to theory calculation, restriction of intramolecular motions accounts for their AIE characteristics. Moreover, a separated distribution of the HOMOs and the LUMOs of these luminogens leads to small ΔEST values and therefore delayed fluorescence.
