摘　　要：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.
