报道了萘基桥联双苯并15-冠-5的合成, 研究了K＋调控的双冠醚自组装过程以及伴随的独特荧光行为. 这种发光行为不仅可以模拟一个荧光"off-on-off"开关和一个荧光"on-off-on"开关, 而且其组装模式和功能上类似于酶的二聚化过程.

This paper reports the synthesis of 1,5-naphthalene-bridged bis-(benzo-15-crown-5), and its distinct fluorescent behavior derived from the self-assembly modulated by K＋. The behavior can mimic a fluorescent "off-on-off" switch and a fluorescent "on-off-on" switch, which is similar to the dimerization and functions of enzyme to some extent.

Key words: dimerization, bis-crown ether, photoinduced electron transfer, excimer
