Abstract:
A series of novel 9,9'-spirobifluorene-bridged donor-π-acceptor chromophores containing triarylamine moieties were easily synthesized starting from the readily available reagent 4,4'-dimethylbiphenyl. These chromophores were found to combine excellent transparency in the visible region, high thermal stabilities, and large optical nonlinearity.
