Fund Project: This research was supported by the National Natural Science Foundation of China (Grant No. 50073018) and the authors are also thankful to the support from the Key Laboratory of Supramolecular Structure and Materials in Jilin University.

Upon excitation of porphyrin or perylene subunit, the porphyrin-perylene dyad exhibits reversible fluorescence emitting and quenching by formation and neutralization of the protonated porphyrin subunit, thereby providing a prototype of molecular fluorescence switch working in an expanded spectral range.
