While <i>para</i>-substituent variation enables continuous emission tuning within the conventional ESIPT framework, N-site acylation drives the evolution toward ESIPT–aggregation-induced emission (AIE) luminogens with large Stokes shifts and bright solid-state fluorescence. The established structure–photophysical relationships reveal the distinct roles of dual-site modulation and provide a rational design strategy for high-performance N–H-type ESIPT luminogens. 2026-09-29T00:00:00Z Text Journal contribution 10.1021/acs.orglett.6c03542.s001 https://figshare.com/articles/journal_contribution/Molecular_Engineering_of_N_H-Type_ESIPT_Fluorophores_Enabling_Tunable_Emission_and_ESIPT-AIE_Integration/34025046 CC BY-NC 4.0
