A new tetrathiafulvalene-anthracence dyad fusion with the crown ether group: fluorescence modulation with Na+ and C60, mimicking the performance of an "AND" logic gate.

In this Note, we describe a new TTF-anthracene dyad fusion with the crown ether unit. It is interesting to find that the fluorescence of this new dyad can be modulated with Na+ and C60, and its fluorescence intensity can be largely enhanced only in the presence of both Na+ and C60. Such fluorescence modulation behavior mimics the performance of a two-input "AND" logic gate.
