摘要：

The fluorescence of a designed water-soluble 4-sulfonato-1,8-naphthalimide dye can be switched on by the synchronous host-guest complexation with cucurbit[7]uril and decrease in pH (from 9 to 7). This affords a dual resettable (by addition of cadaverine as competitor or by deprotonation) logic gate based on modulation of photoinduced electron transfer.
