Unveiling the Effect of π-Chain on Competitive Radiative and Non-Radiative Decay in Pyrene-Based Schiff Bases: ESIPT-AIE Fluorophores.
Organic fluorophores combining excited-state intramolecular proton transfer (ESIPT) and aggregation-induced emission (AIE) offer enhanced photoluminescence properties. Herein, we have adopted a significant distance strategy for asymmetric pyrene Schiff bases (HPBC and 1HPBC) to disclose their concurrent fluorescence me...
