In order to develop highly efficient, bright, and stable fluorescent organic materials composed of ubiquitous elements, we constructed supramolecular assemblies of polycyclic aromatic hydrocarbons with acidic moieties(functional groups) and various amines(structural modulation groups), and investigated their emission properties. As a result, we achieved wide range of emission intensity and color from blue to nearly red by controlling weak interactions which inhibits molecular vibration, varying arrangements of pi-molecules in horizontal direction as well as in vertical one, and adding the third components.
