Abstract
Here we report the synthesis and characterization of
a series of annelated benzotriazole based polymers with variable bandgap.
Benzobistriazole monomers reported by us previously were desymmetrized
using partial reduction ring opening followed by ring closure to produce
a wide range of annelated benzotriazole based monomers. These monomers
were co-polymerized with a fluorene moiety to give polymers with bandgaps
ranging from 1.16 to 2.41 eV
