Unfortunately, peripheral electronic changes in the boramidine scaffold resulted in minimal changes in the violet-blue emission of the molecule. In this paper, we envisioned applying our modular boron heterocycle synthesis to the development of a highly tunable class of fluorescent emitters. The boramidine scaffold is transformed by a N-to-C substitution to afford a boron analog of indolizineborindolizine (Figure ). In this manner, we access B-N variants of known C-C heterocycles through a deep-seated scaffold modification on the 5-membered boron heterocyclic core to study the impact of structure on the emission wavelength.
