## Description

- description: Formaldehyde (FA) is a common pollutant found indoors and outdoors,
    posing a significant threat to human health. Therefore, developing sensitive and
    efficient detection methods for FA is essential for environmental monitoring and
    protecting public health. Herein, we report a naphthalimide-conjugated water-soluble
    polymeric fluorescent probe for the detection of FA in both aqueous and vapor
    phases using fluorimetric methods. The aromatic amines present in the side chain
    of the polymer react with FA, forming a Schiff base (imine bond). This imine formation
    inhibits the photoinduced electron transfer (PET) process within the polymer,
    leading to a ‘turn-on’ fluorescence under 365 nm UV light. The probe is capable
    of selectively sensing FA with a detection limit as low as 1.36 nM in aqueous
    medium. The formation of imine is confirmed for the model reaction between 6-(4-aminophenyl)-2-(4-((4-vinylbenzyl)oxy)phenyl)-1 h-benzo[de]isoquinoline-1,3(2 h)-dione
    and FA by electrospray ionization mass spectrometry (ESI-MS) and nuclear magnetic
    resonance (NMR) titration methods. The mechanism behind ‘turn-on’ FA sensing is
    investigated using density functional theory (DFT) analysis. Additionally, the
    study demonstrates a facile approach for covalently attaching the polymer on the
    surface of a filter paper surface via ultraviolet (UV) light-induced cross-linking.
    Such polymer attached paper exhibits FA vapor sensing through changes in fluorescence
    intensity.
