ABSTRACT We report a dual‐mode fluorescence sensing of multi‐analytes like silver and permanganate ions by adopting selective oxidation strategy in poly(N‐phenyl anthranilic acid ‐co‐ o‐phenylenediamine) copolymer. The P(NPA‐ co ‐OPD) copolymers were synthesized situ oxidative chemical polymerization N‐phenyl (NPA) o‐phenylenediamine (OPD) comonomers using ferric chloride as oxidizing agent. Proton ( 1 H) carbon 13 C) nuclear magnetic resonance spectra Fourier transform infrared revealed the higher reactivity NPA compared to OPD copolymers. Monomer ratios calculated from Fineman–Ross method also indicated monomer copolymerization. Powder X‐ray diffractograms differential scanning calorimetry (DSC) thermograms development crystallinity Field emission electron microscopic images (FE‐SEM) high‐resolution transmission (HR‐TEM) morphological transformation semi‐micro‐spherical‐shaped poly‐N‐phenyl micro‐rod‐shaped poly‐o‐phenylenediamine (POPD) into micro‐blocks/microrod‐shaped Poly‐o‐phenylenediamine has yellow emission, (PNPA) blue neutralized medium. was dominated due PNPA fragments than POPD copolymer chain, except for 10:90, which dominant properties 10:90 selectively tuned adding AgNO 3 , indicating semi‐oxidation and, subsequently, colorless acidified KMnO 4 complete both response suggests ability distinguish between mild or strong agents via oxidation.

The structural modification of metal-organic frameworks (MOFs) is vital importance in many fields, especially sensing with enhanced performance, while the efficient synthesis functionalized MOF nanoparticles toward small molecule detection remains challenging. Here, a general cellulose nanofibril (CNF)-induced situ one-step strategy was proposed for dual-ligand-functionalized europium-based (EuMOF@CNF) under an effective regulation crystallization kinetics hydrothermal synthesis. Based on unique dual-ligand structure, obtained EuMOF featured tunable antenna effect and laid good foundation fluorescence-sensing materials. Benefiting from superior self-assembly properties CNFs EuMOF@CNF, flexible films were constructed, showing excellent mechanical (72 MPa stress 3.8% strain) luminescence achieving instant (1 s) sensitive fluorescence sarin analogue vapor significantly low limit (LOD, 2.8 ppb) robust selectivity against wide range common interferents (>14 types), independent acids. We believe that this pioneering design effects would positively advance development high-performance MOF-based fluorescent materials devices.
