描述了结合了新的萘二甲酰亚胺三唑鎓基团的阴离子模板的轮烷结构合成,并显示了互锁的主体表现出选择性的,单向的,阴离子诱导的穿梭。最初的拟轮烷研究证明了萘二甲酰亚胺三唑鎓螺纹组件具有与反阴离子相关的共构象的互穿组件的能力。1个1 H NMR研究表明类似轮烷主体系统的穿梭行为受选择性阴离子结合和溶剂条件的性质控制。完全的大环易位只有在识别出较小的卤化物阴离子(氯离子和溴离子)时才会发生。氯化物存在下轮烷的固态晶体结构与溶液相共构象一致。轴萘二甲酰亚胺吸收带对互锁结构中大环组分位置的敏感性使得可以通过UV / Vis光谱观察分子运动,而六氟磷酸银的加入则逆转了氯化物引起的轮烷的穿梭。

in a proof of concept study to prepare a heterogeneous sol−gel based material which retains its PET response to Zn(II). The versatile nature of the sol−gel process importantly allows the simple preparation of a variety of nanostructured materials displaying high surface area-volume ratio using fabrication methods such as softlithography, electrospinning, and nanopipetting.

the CuAAC activetemplate reaction not only is it demonstrated to be possible to use smaller macrocycles, but, surprisingly, that smaller macrocycles lead to higher yields of rotaxane product (see scheme). The synthesis of “small” functionalized [2]rotaxanes showcases this as a method for the production of materials with potentialapplications in molecular electronics, drug delivery, sensing, and enantioselective

Although the central role that zinc plays in many biological processes and important disease states is now well-established, there remains a pressing need to develop an absolute understanding of the underlying biology of zinc trafficking in terms of its dynamic and quantitative processing in specific organelles. Here we describe the modular synthesis of zinc sensors using a âclickâ approach and demonstrate the applicability of our new sensors in vivo using a zebrafish model.
