報(bào)告摘要：
Three-coordinate boron, with a vacant pz-orbital and isoelectronic with a carbonium ion, can conjugate with organic π-systems as a strongp-acceptor in the excited state. Most 3-coordinate boron compounds are Lewis acidic, bind Lewis bases which disrupt this conjugation, and are sensitive to hydrolysis. Bulky substituents on B, such as mesityl (mes) groups, provide steric protection of the vacant p-orbital without disrupting the electronic communication with a π-system, resulting in compounds which are usually air and water stable. In aqueous solution, as required for biological applications, we require additional steric protection to avoid hydrolysis. We focus on the synthesis of dipolar, quadrupolar and octupolar compounds containing B(Ar)2groups, including those containing newp-acceptors considerably stronger than B(mes)2, and their linear and nonlinear (2nd and 3rd order NLO, TPA and TPEF) optical properties, and their applications, including one- and two-photo excited fluorescence imaging in live cells.
