Similarities attract: The designed coordinationprism (see graphic; Cu orange, N blue, C gray), based on the renowned CuI‐pyrazolate trimer, features an unprecedented stacking mode and an unusual, luminescent Stokes shift of 23470 cm−1, which is elucidated by DFT calculations.
相似之处吸引人:基于著名的Cu I-吡唑酸酯三聚体,设计的协调棱镜(见图表; Cu橙色,N蓝色,C灰色)具有前所未有的堆叠模式和23470 cm -1的不寻常的发光斯托克斯位移,通过DFT计算得以阐明。

one-dimensional chain structures in which copper(II) centres on different dinuclear platforms are linked in a 'zigzag' fashion. In contrast, with 2,2'-dipyridylamine (dpa) a discrete complex of type [Cu2L2(dpa)2] formed in which one potential pyridyl donor from each 2,2'-dipyridylamineligand remains uncoordinated.

The synthesis of new cationic macrocyclic host molecules is described. These macrocycles are comprised of glycoluril oligomers linked to two pyrazolium groups, which form part of a cationic wall facing into their cavities. A number of derivatives have been prepared with an objective to increasing the cavity size, and each new product has been fully characterized. Preliminary investigations of pKas
