Shape-persistent macrocycles and planar organometallic complexes are beginning to show considerable promise as building blocks for the self-assembly of a variety of supramolecular materials including nanofibers, nanowires, and liquid crystals. Here we report the synthesis and characterization of a family of planar di- and tri-silver(I) containing metallo-macrocycles designed to self-assemble into novel metal−organic
形状持久的大环化合物和平面有机金属络合物开始显示出可观的前景,作为自组装各种超分子材料(包括纳米纤维,纳米线和液晶)的基础。在这里,我们报告了合成的平面二-和三-银(I)族金属-大环的合成和表征,这些金属-大环旨在通过π堆积和金属-金属相互作用的组合而自组装成新型金属有机纳米管。银(I)配合物已通过元素分析,高分辨率电喷雾电离质谱(HR-ESI-MS),IR,1 H和13进行了全面表征1 H NMR光谱和溶液数据与金属大环的形成一致。使用X射线晶体学已对其中的四种配合物进行了结构表征。然而,仅发现与1,3-双(吡啶-3-基乙炔基)苯形成的二银(I)配合物在固态下保持其大环结构。二-银(I)形状持久的大环组装成状结构的纳米多孔鸡线,和C10 4 -阴离子和无序ħ 2水分子填充孔。2,6-双(吡啶-3-基乙炔基)吡啶和1,4-二(3-吡啶基)丁-1,3-二炔开环的银(I)络合物开环并结晶为无孔配位聚合物。
