主讲人简介：Prof. Dr. Dr. h.c. Todd B. Marder received his B.Sc. from M.I.T. and Ph.D. from UCLA, was a postdoc at the University of Bristol (UK), and a Visiting Research Scientist at DuPont Central Research (USA). He joined the faculty at the University of Waterloo, Canada in 1985, moved to the University of Durham (UK) in 1997 as Chair of Inorganic Chemistry, and to the University of Würzburg, Germany in 2012 as Chair I of Inorganic Chemistry. Awards include: Royal Society of Canada Rutherford Memorial Medal for Chemistry (Canada), RSC Awards in Main Group Element Chemistry and in Organometallic Chemistry (UK), JSPS Invitation Fellowship (Japan), Humboldt Research Award (Germany), Royal Society Wolfson Research Merit Award (UK), Fellow of the RSC (UK), Member of the Bavarian Academy of Sciences (Germany), Fellow of the American Association for the Advancement of Science (AAAS) (USA), Fellow of the European Academy of Sciences, 1000-Foreign Talents Award for Foreign Experts (China, declined), and Docteur Honoris Causa, Université de Rennes 1 (France). He has published >375 papers (>24,500 citations, h-index = 87 Web of Science, h-index = 91 Google Scholar) and presented >400 invited lectures worldwide. He has held Visiting Professorships (UK, France, Hong Kong, China, Japan, India, and Australia), and holds an Honorary Professorship at Durham University (UK), an Adjunct Professorship in Chemistry at the Hong Kong University of Science and Technology, a Guest Professorship at Shandong University, a Visiting Professorship at Northeast Normal University and a Consultant Professorship at Northwestern Polytechnical University (China). He has served on the editorial boards of Organometallics, Inorganic Chemistry, Journal of Organometallic Chemistry, Polyhedron, Inorganica Chimica Acta, Applied Organometallic Chemistry, Canadian Journal of Chemistry, Chinese Journal of Chemistry, and Crystal Engineering. Over 35 of his former co-workers hold academic positions around the world. Marder’s diverse research interests include synthesis, structure, bonding and reactivity of organometallic and metal–boron compounds, homogeneous catalysis, conjugated organic, organoboron, and organometallic compounds, luminescence, non-linear optics, bioimaging, liquid crystals, and crystal engineering.
主讲内容：Three-coordinate boron, with a vacant pz-orbital and isoelectronic with a carbonium ion, can conjugate with organic π-systems as a strong p-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. By suitable modification, they can also be made water soluble. We focus on the synthesis of dipolar, quadrupolar and octupolar compounds containing B(Ar)2 groups, including those containing new p-acceptors considerably stronger than B(mes)2, and their linear and nonlinear (2nd and 3rd order NLO, TPA and TPEF) optical properties, and their various applications which include OLEDs, cell imaging, and DNA/RNA/protein binding.
