Cooperative supramolecular polymerization of styrylpyrenes for color-dependent circularly polarized luminescence and photocycloaddition.

ABSTRACT: Developing facile and efficient methods to obtain circularly polarized luminescence (CPL) materials with a large luminescence dissymmetry factor (g_lum) and fluorescence quantum yield (Φ_Y) is attractive but still challenging. Herein, supramolecular polymerization of styrylpyrenes (R/S-PEB) is utilized to attain this aim, which can self-assemble into helical nanoribbons. Benefiting from the dominant CH-π interactions between the chromophores, the supramolecular solution of S-PEB shows remarkable blue-color CPL property (g_lum: 0.011, Φ_Y: 69%). From supramolecular solution to gel, the emission color (blue to yellow-green) and handedness of CPL (g_lum: -0.011 to +0.005) are concurrently manipulated, while the corresponding supramolecular chi
