Abstract
Stable crosslinked π-conjugated organoboron polymers and poly(cyclodiborazane)s were prepared by hydroboration polymerization or allylboration polymerization. The obtained gels, especially prepared by allylboration polymerization using 2,5-dicyanothiophene, 1,3,5-tricyanobenzene and triallylborane, showed good thermal stability and bathochromic shifts were observed in UV-vis absorption spectrum and the fluorescence emission spectrum, probably due to the interaction between polymer chains and more planer structure of crosslinked polymers.
