Solid-state luminescence controlled by transformation of nano-assembled structure has a problem in its poor amount of change in luminescence. We have successfully demonstrated that combination of ESIPT, a process that its properties would be directly affected by a molecular conformation, and mesoscopic effect derived from nano-assembled structure caused quite large (‘enhanced') change in luminescence properties. Moreover, combining with synthetic modification of the electronic state showed promising results for developing various types of luminescence materials.
