Molecular stacking dependent phosphorescence-fluorescence dual emission in a single luminophore for self-recoverable mechanoconversion of multicolor luminescence.

A self-recoverable mechanoconversion of multicolor luminescence was observed by crystallization-induced self-assembly. Such a self-assembly led to the formation of nanorods with different molecular stacking modes, thus making the phosphorescence/fluorescence proportion alterable. Therefore, multicolor luminescence of the single luminophore can be achieved by a straightforward reversible mechanical stimulus.
