A novel aggregation-induced emission (AIE)-based artificial light-harvesting system (LHS) is successfully assembled via the host-guest interaction of bis-naphthylacrylonitrile derivative (BND), water-soluble pillar[5]arene (WP5), and sulforhodamine 101 (SR101). After assembly, formed WP5⊃BND complexes spontaneously self-aggregated into nanoparticles (donors) SR101 (acceptors) introduced to fabricate WP5⊃BND-SR101 LHS. Through investigation energy transfer between donors acceptors, processes are certified in LHS absolute fluorescence quantum yields (Φf(abs)) significantly improved from 8.9% (for WP5⊃BND) 31.1% WP5⊃BND-SR101), exhibiting excellent capabilities. Notably, by tuning donor/acceptor (D:A) molar ratio 250:1, a conspicuous white light (CIE coordinate (0.32, 0.32)) realized yield (Φf(abs) WP5 ⊃ BND-SR101-White) 29.2%. Moreover, antenna effect (AEWP5 can reach 36.2, which higher than that recent LHSs water environments, suggesting vast potential applications aqueous LHSs.
