Abstract

Upon photoirradiation of a stilbene-cored poly(glutamate) dendrimer, the photocrosslinking reaction preferentially occurred to produce the [2 + 2] cycloadduct in benzene. In addition, blue-shifted absorption spectra and a bisignate circular dichroism (CD) signal were observed, indicating that the aggregates of the stilbene core were chiral.
