title: Aggregation-induced emission of tetraphenylethene-hexaphenylbenzene adducts: effects of twisting amplitude and steric hindrance on light emission of nonplanar fluorogens.
abstract: A series of nonplanar tetraphenylethene (TPE)-hexaphenylbenzene (HPB) adducts was designed and synthesized by Diels-Alder reaction of the acetylene precursors and tetraphenylcyclopentadienone. All of the adducts showed aggregation-induced emission features. The twisting amplitude and steric hindrance of the TPE and HPB units were found to play a crucial role in their fluorescence behaviors in the aggregated state.
