摘要：

In this study, poly[2-(4'-vinylphenyl)-3,4,5-triphenylthiophene] (PTP) with pendant tetraphenylthiophene (TP) groups was synthesized to study its aggregation-induced emission (ALE) property. The solution emission spectra of the PTP nanoaggregates contain discernible monomer and aggregate bands with their relative intensity dependent on the extent of aggregation. Increasing solution concentration or nonsolvent content resulted in the increase of the aggregate to monomer emission ratio. In addition, the aggregate to monomer emission ratio decreases when the PTP film was heated across the glass transition temperature (165 degrees C). Single-chain conformation of PTP was simulated to probe for the possible arrangements of the pendant TP fluorophores in the isolated (monomer) and the aggregate domains.
