In order to examine the effect of the electronic properties and the position of the substituents on AIE properties, an expedient method for the synthesis of a series of pentaarylated cyclopentadiene derivatives was devel- oped, and their UV-Vis, fluorescence spectra, fluorescence quantum yields as well as the XRD structures of single crystals were investigated. The AIE properties of pentaarylated cyclopentadiene derivatives
