attracted increasing attention. A series of combinational logic circuits at the molecular level have been constructed, however, the development of sequential logic circuits is still in its infancy due to the lack of ideal design tools. Taking advantage of unique assembly behaviors of cyanine dyes, we constructed a two‐bit molecular counter circuit that can implement fundamental sequential logic functions
分子计算是一个快速发展的多学科研究领域,受到越来越多的关注。已经构建了一系列分子
水平的组合逻辑电路,但是由于缺乏理想的设计工具,顺序逻辑电路的发展仍处于起步阶段。利用花菁
染料独特的组装行为,我们构建了一个两位分子计数器电路,该电路可以实现基本的顺序逻辑功能,包括数字累加和降序。进一步引入富含
鸟嘌呤的DNA链作为循环指数,该计数器可以重复使用几次,最终可以放大到最多16个数字。超分子电路显示出高度的可编程性,灵活性和可逆性,
