Summary: A highly emissive photofunctional porous organic polymer film (polyPhTPECz) was constructed using an in situ electropolymerization method. The film showed excellent multifunctional and reusable luminescent sensor abilities for 2,4,6-trinitrophenol (TNP) and Fe3+ in aqueous media, with low detection limits and sensitive detection for TNP vapor. The fluorescence-quenching mechanism for TNP was a combination of electron transfer and resonance energy transfer due to the high fluorescence property and cross-linked porous texture of the polyPhTPECz films.

Summary: Lanthanidemetal-organic frameworks (Ln-MOFs) with exceptional optical performance and structural diversity offer a unique platform for the development of luminescent materials. However, Ln-MOFs often suffer from luminescence quenching by high-vibrating oscillators, especially in aqueous solution. Thus, multiple strategies have been adopted to improve the luminescence of Ln(3+).

Summary: Since the discovery of aggregation-induced emission (AIE), the development of new AIE fluorogens (AIEgens) has become a significant field. This study focuses on altering the substituents of quinoline derivatives to achieve the conversion from aggregation-caused quenching (ACQ) to AIE. The experimental results reveal that the behavior of the derivatives can be converted by changing the electron-donating and electron-withdrawing groups (EDG and EWG).

Summary: Aggregation-induced emission (AIE) is a novel phenomenon that has attracted significant attention. Existing research on AIE has mainly focused on the impact of molecular structures and solvents on AIE behavior, with limited exploration of the interaction between solvents and AIE aggregates. In this study, a series of AIE molecules were designed and synthesized, and the impact of solvents on their fluorescence properties was investigated. It was found that water molecules not only induce aggregation and inhibit nonradiative transitions, but also trigger fluorescence through hydrogen bond donation. These findings provide new insights for the design of AIE molecules.
