报告摘要：Coordination-driven self-assembly has proven to be a powerful means of synthesizing various discrete supramolecular metallacycles and metallacages.1 Therein, a single metal atom featuring specific coordination geometry often acts as coordination centers. In contrast, discrete coordination self-assembled metallosupramolecules involving polynuclear metal clusters as centers are scarcely reported to date. In the past two years, we have endeavored to establish a synthetic strategy for the construction of metal cluster-involved supramolecular architectures from zero (0D) to three dimensional (3D) (see the Figure). A series of metal cluster-centered supramolecular complexes have been built by silver-acetylide clusters and macrocyclic azacalix[n]pyridine ligands.2-5 Potential applications of these complexes are being extended by us to the following research fields: (i) new metal cluster-based functional materials, (ii) supramolecular catalysts, (iii) supramolecular polymer based on metal cluster-macrocycle building blocks, and (iv) bio-inspired molecular recognition and enzyme mimic.

报告人简介：Liang Zhao (赵亮) was born in 1981 at Ningxia Hui Autonomous Region of China. He obtained his B.S. degree from the Chemistry College at Peking University in 2002. From 2003 to 2007, he pursued his PhD degree in the Chemistry Department of Chinese University of Hong Kong under the guidance of Prof. Thomas C. W. Mak (麦松威院士). Subsequently, he joined Prof. Peter J. Stang’s group at University of Utah and completed two-year postdoctoral studies until September 2009. In November 2009, he was appointed Associate Professor of Chemistry Department at Tsinghua University. His research work is focused on (i) synthesis of organic and organometallic macrocycles, (ii) metal cluster-centered coordination self-assembly, (iii) synthesis of high-nuclearity metal clusters and nanoparticles assisted by multidentate organic or organometallic ligands.
