제목 Aggregation induced emission properties of triphenylamine-o-carborane dyads
초록 We developed unique electron donor-π-acceptor dyad systems with diphenylamino at para- and meta-position of phenyl, and ortho-carborane. The para- and meta-substituted D- π -A systems showed three kinds of emission originated from the local excited state, a twisted intramolecular charge transfer state and an aggregation induced emission. The TICT emission showed strong solvent-polarity dependency, which is attributed to the dipole moment changes in excited TICT state. The strong AIE emission is observed in extremely nonpolar solvent such as n-hexane. Contrast to these, the steric hindrance between donors in para-substituted of D- π -A- π -D system prohibited the formation of TICT state, hence the LE and AIE emissions were observed dominantly.
