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.
