Synthesis and reactivity of a bis(dimesitylboryl)azaborine and its fluoride sensing ability.

ABSTRACT

An azaborine bearing two dimesitylboryl groups on its periphery showed very strong light absorption and moderate photo-luminescence emission; the reaction of the title compound with fluoride ion resulted in multi-step fluoride ion complexation on the boron atoms of the dimesitylboryl groups, producing mono- and bisfluoroborates.
