摘要：Two novel octupolar organoboron compounds, namely l,3,5-tris[5-(dimesitylboryl)thiophen-2-yl]terthienobenzene and l,3.5-tris[4-(dimesitylboryl)phenyl Jterthienobenzene, 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 (φ_(fl) > 30%), as well as good thermal stability (T_g > 150 °C).
