标题:Asymmetric synthesis catalyzed by transition metal complexes with rigid chiral ligands
发明人：ZHANG XUMU
权利人:PENN STATE RES FOUND
摘要:This invention is to develop novel transition metal catalysts for the practical synthesis of important chiral molecules. The invention emphasizes asymmetric catalysis based on chiral bidentate phosphine ligands with cyclic ring structures which could be used to restrict conformational flexibility of the ligands and thus the efficiency of chiral transfer can be enhanced through the ligand rigidity.

标 题 :Performance of energy storage devices: potential areas for dendritic chemistry involvement
发明人：NEWKOME GEORGE R
权利人:NEWKOME GEORGE R
摘要:A compound consists of a fractal-like, plain or organometallic array useful for energy storage devices. A dendrimer useful in the synthesis of the fractal-like compound includes a single ligating moiety bound to a surface of each quadrant of the dendrimer. A method of making metallo-based (macro) molecules includes the steps of combining monomers selected from the group consisting of bipyridal- and terpyridal-based ligands with connecting metals and self assembling macrocycles wherein the monomes are interconnected by the metals.
