Two new conjugates, hcptpyDP and hcptpyTP, of a terpyridine derivative incorporating artificial peptide moieties, have been synthesized and their use in the preparation of metal catalysts and organogelators has been investigated. Ru(II) complexes derived from these ligands showed electrochemical behavior and activity as catalysts in the epoxidation of olefins similar to that of Beller's catalyst. As
已经合成了掺入人工肽部分的三联吡啶衍生物的两种新的缀合物hcptpyDP和hcptpyTP,并研究了它们在制备金属催化剂和有机胶凝剂中的用途。衍生自这些配体的Ru(II)配合物在烯烃的环氧化中表现出与贝勒催化剂相似的电化学行为和活性。作为有机胶凝剂,这些共轭物能够以令人满意的mgc凝胶化从甲苯到甲醇的多种溶剂(最小胶凝浓度)值。4'-(4-羧基)苯基联吡啶(hcptpy)部分的存在允许调节胶凝性质,并且还影响超分子自组装模式以产生相对于亲本肽DP和TP的手性聚集体。在偶联物的情况下,由芳族结构部分提供π-π相互作用与N-之间的分子间氢键合作ħ和C Ó在酰胺基团。考虑到未来的应用,正在研究肽/吡啶吡啶共轭物的其他性质。
