a The UV/Vis absorption spectra in THF solution (c = 10 μM). b The photoluminescence (PL) spectra in THF solution (c = 10 μM, λex = 380 nm). c The emission intensity of 3aa in a THF/H2O mixture with increased H2O volume fraction (fw) to 99% (c = 10 μM, λex = 380 nm). d Relative emission intensity of 3aa. e The αAIE of 3aa, 3ac, 4ad, 5aa2, 3ba, 3ea and Model-1. f The solid-state luminescence of the selected products. Insets are the absolute luminescence efficiency, CIE (Commission Internationle de l’Eclairage) coordinates, and emission peaks. g The chiral crystal structures of 3aa-Rp and 3aa-Sp. h The CD spectra of 3aa-Rp and 3aa-Sp in THF. i The CPL spectra of 3aa-Rp and 3aa-Sp in PMMA with a weight ratio of 1:100.
