A rigid nanosized hexagonal phenylethynyl cyclophane 5 has been prepared, which incorporates two 2,2':6',2"-terpyridines as integral structural units, for the purpose of binding metal ions. Macrocycle 5 was obtained by a 14-step synthesis in an overall yield of 11 %, and was characterised by spectroscopic techniques. The efficiency and ease of all transformations, and the relatively enhanced yield
重要的是,发现5是荧光发色团,因此可能潜在地用作检测金属离子和氢键捐赠生物底物的新感觉平台。5的结构明确定义的纳米形态以及其有趣的光谱特性,支持以下期望:5和相关体系结构将在纳米化学和纳米科学的发展领域中获得大量的未来应用。
