A bidentate ligand based on N-monoaryl 4,4'-bipyridinium undergoes self-assembly to dinuclear rectangular metallocycles upon coordination to palladium(II) and platinum(II) centers. These metallocycles form a very stable complex with pyrene in aqueous solution and in the solid state. A crystal structure of the pyrene inclusion complex is presented. The association constants between pyrene and metallocycle 3a in organic solvents and water (K(a) = 2.3 x 10(6)) were determined.
一种基于 N-单芳基 4,4'-联吡啶鎓的双齿配体在与钯(II)和铂(II)中心配位时会自组装成双核矩形金属环。这些金属环在水溶液中和固态中与芘形成非常稳定的配合物。本文展示了芘包合物的晶体结构。还测定了有机相和水相中芘与金属环 3a 的结合常数(K(a) = 2.3 x 10(6))。
