以乙炔前驱体和四苯基环戊二酮为原料，通过DielsAlder反应，设计合成了一系列非平面的四苯基六苯基苯(HPB)加合物。所有的加合物都表现出聚集诱导的发射特征。TPE和HPB单元的扭曲幅度和空间位阻对其聚集态的荧光行为起着至关重要的作用。
A series of nonplanar tetraphenylethene (TPE)hexaphenylbenzene (HPB) adducts was designed and synthesized by DielsAlder 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.
