Two novel octupolar organoboron compounds, namely 1,3,5-tris[5-(dimesitylboryl)thiophen-2-yl]terthienobenzene and 1,3,5-tris[4-(dimesitylboryl)phenyl]terthienobenzene, symmetrically extended from terthienobenzene (TTB) with dimesitylboryl groups as electron acceptors have been synthesized. These TTB derivatives exhibited strong blue-green emission in common solvents under single or two-photon excitation (Φfl > 30%), as well as good thermal stability (Tg > 150 °C).
