The design and synthesis of novel cage and capsule-like supermolecular structures will be undertaken, including rare examples of two large cage types - one designed to incorporate two adjacent metal ions in an extended (chiral) cavity while the other utilises macrocyclic metal complexes as the 'walls' of the cage. In the latter case metal variation makes possible the alteration of the electronic environment of a guest occupying the central cavity . A third (capsule-like) system is designed to 'open' and 'close' under pH control. The present studies hold promise for underpinning the future development of nano-scale molecular devices.

将进行新型笼状和胶囊状超分子结构的设计和合成，包括两种大型笼型的罕见例子--一种旨在将两个相邻的金属离子合并到扩展的(手性)空腔中，而另一种利用大环金属络合物作为笼子的‘壁’。在后一种情况下，金属变化使占据中心腔的客体的电子环境发生改变。第三个(胶囊状)系统被设计成在pH控制下“打开”和“关闭”。目前的研究为未来纳米级分子器件的发展奠定了基础。
