Diphenolic acid/furfurylamine‐based bio‐benzoxazine (DPA‐fa‐Boz) was selected here as the starting material to prepare a phenol hydroxyl‐containing polyamide (PA) derivative, PA‐DFB, via sustainable benzoxazine‐isocyanide mechanochemistry (BIC‐MC). Further, a type of PA/phosphazene‐based, organic–inorganic covalent hybrid (PD‐HCCP), which comprises various N/P/O‐containing substructures (NP ring, amide, carboxylic acid, and tertiary amine), was successfully prepared by the condensation between PA‐DFB and hexachlorocyclotriphosphazene (HCCP). The presence of heteroatoms‐containing segments endows PD‐HCCP with specific affinity for some cationic agents. PD‐HCCP's binding capability for Pb(II) can be feasibly utilized for the detection of this heavy metal. The downstream application investigation of PD‐HCCP revealed that it can be used as an enrichment‐type Pb(II) electrochemical probe, characterizing a wide detection range (1–40 μM) and a low detection limit (0.0245 μM). Meanwhile, PD‐HCCP also showed the selective binding for cationic dye, methylene blue (MB), providing a maximum adsorption capacity of ~424.97 mg/g and a high adsorption rate (with 98% removal efficiency at 6 min), with the pseudo‐second‐order rate constant up to 0.0325 g mg ⁻¹ min ⁻¹ .

Room-temperature preparation of polymer-based covalent hybrids, which with multiple functional characteristics, is instrumental to overcome the performance shortcomings of single-polymer materials and broaden their applications thus. Herein, by introducing chitosan (CS) as a starting substrate into benzoxazine-isocyanide chemistry (BIC)/sol-gel reaction system, a novel polyamide (PA)/SiO2/CS covalent hybrid (PA-Si-CS) was successfully prepared in-situ at 30 °C. PA-Si-CS's chemical structure and elementary properties were characterized here. The introduction of CS combining with the presence of diverse N, O-containing segments (amide, phenol -OH, Si-OH, etc.) in PA-Si-CS provided its synergistic adsorption for Hg2+ and anionic dye Congo red (CR). The capture of PA-Si-CS for Hg2+ was rationally applied to the "enrichment"-type electrochemical probing of Hg2+. Relevant detection range, detection limit, interference, and probing mechanism were systematically analyzed. Compared with the experimental results of control electrodes, the electrode modified with PA-Si-CS (PA-Si-CS/GCE) showed a significantly enhanced electrochemical response to Hg2+, with a detection limit up to ~2.2 × 10-8 mol/L. In addition, PA-Si-CS also exhibited the specific adsorption for CR. Systematic analyses of dye adsorption selectivity, kinetics, isothermal models, thermodynamics, and adsorption mechanism told that PA-Si-CS can be used as an efficient CR adsorbent, with a maximum adsorption capacity of ~348 mg/g.
... The N1s spectrum contains three peaks located at 398.47 eV (P-N=P), 400.09 eV (C=N-C), and 401.87 eV. The peaks assigned to P-N=P and C=N-C bonds are part of the cyclotriphosphazene structure and aromatic heterocycles containing nitrogen, respectively [55,56]. The binding energy peak at 401.87 eV is attributed to the hydrogen-bonded amine that forms between P-NH-Ph bonds [57]. ...

... The important aspect in chemically modified electrodes (CMEs) is the choice of the modifier, which confers unique characteristics to the electrode surface. [28][29][30][31] Asymmetric Schiff base ligand was chosen as the modifier in this work because it readily complexes with transition metal ions such as mercury, lead, and cadmium. Schiff base ligands play a key role as chelating agents in main group and transition metal coordination chemistry, due to the ease of synthesis, their role in biological systems, and diverse therapeutic activities. ...

The triphenylamine unit, with its propeller structure, excellent electron-donating ability, and easily modified molecular structure, can serve as an excellent emitting group for small molecular fluorescence probes and has become a research hotspot in recent years [19]. Based on our previous studies [23][24][25][26][27][28][29][30][31][32], trianiline is modified by introducing 4-bromo-2hydroxybenzaldehyde through a Suzuki coupling reaction to increase its conjugation degree and electron-giving ability, improving its optical properties. It also undergoes condensation with salicylhydrazine to introduce Schiff base structures, enhancing its coordination ability with copper ions to achieve rapid detection and high selectivity. ...
