通过合成主体的封装可以转换正方形平面Ni（II）（acen）和Co（II）（tap）配合物的自旋状态。在封装时，红色Ni（II）抗磁性状态被转换成绿色顺磁性状态，而Co（II）低自旋（S = 1/2）状态被改变成耦合（S = 1/2和S = 3/2）状态。的主机笼是非无辜的和主机-客体的相互作用内的封闭腔的影响所得到的性能的包合物的金属配合物。
Encapsulation by synthetic hosts can transform the spin states of square planar Ni(II)(acen) and Co(II)(tap) complexes. Upon encapsulation, the red Ni(II) diamagnetic state was converted into a green paramagnetic state, whereas the Co(II) low spin (S = 1/2) state was changed into a coupled (S = 1/2 and S = 3/2) state. The host cages are noninnocent and host-guest interactions within the confined cavity influence the resultant properties of the enclathrated metal complexes.
