摘要合成了一系列新的圆盘状配合物，双[1,3-二（p-n-烷氧苯基）丙烷-1,3-二羟基]铜（II）（简称CnO-Cu， n = 1-12）。从c30 - cu到c12 - cu的配合物都是盘状的，而且每个配合物都只有一个盘状中间相。据我们所知，c30 - cu是第一个被最短侧链取代的化合物。c30 - cu ~ c50 - cu的亚胚织构为马赛克织构，c60 - cu ~ c12 - cu的亚胚织构为大破碎扇形织构。由Le Chatelier-Schroder关系计算的共晶点与c80 - cu和C8-Cu二元相图中发现的共晶点吻合较好。这是有机过渡金属配合物的盘原中这种一致性的第一个例子。通过x射线衍射测量首次确定了c60 - cu - c12 - cu络合物的盘状中间相均为盘状层状相。很明显，这……
Abstract A new series of disk-like complexes, bis[1,3-di(p-n-alkoxyphenyl)propane-1,3-dionato]copper(II) (abbreviated as CnO-Cu, n = 1-12), has been synthesized. It was found that each of the complexes from C3O-Cu to C12O-Cu is a discogen, and that each of them has only one discotic mesophase. C3O-Cu is the first compound substituted by the shortest side chains in the discogen, so far as we know. The mesomorphic textures could be observed as mosaic textures for C3O-Cu ~ C5O-Cu and as big broken fan-like textures for C6O-Cu ~ C12O-Cu. The cutectic point calculated from Le Chatelier-Schroder relations agrees well with the found eutectic point in the binary phase diagram between C8O-Cu and C8-Cu. This is the first example of such agreement in the discogens of the organic transition metal complexes. It has been established for the first time from X-ray diffraction measurements that each of the discotic mesophases in the complexes from C6O-Cu to C12O-Cu is a discotic lamellar phase. It becomes clear that this ...
