1：Experimental Design and Method Selection:

The study employed solvothermal and sonochemical methods for synthesis. The solvothermal method involved heating at 90°C for 16 hours, while the sonochemical method used ultrasonic irradiation at room temperature with pyridine as a modulator.

2：Sample Selection and Data Sources:

Zinc nitrate hexahydrate and Hpzt ligand were used as reactants. Samples were characterized using FT-IR, PXRD, TGA, SEM, luminescence spectroscopy, and UV-Vis spectroscopy.

3：List of Experimental Equipment and Materials:

Equipment included a Bruker Tensor 27 FT-IR spectrophotometer, PANalytical EMPYREAN X-ray diffractometer, PerkinElmer PE 2400CHNS analyzer, Hitachi STA7200 thermal analyzer, Elmasonic S30H sonicator, SNE-4500M SEM, SHIMADZU RF-6000 Spectro fluorophotometer, and Shimadzu UV 2450 spectrometer. Materials included Zn(NO3)2·6H2O, Hpzt, pyridine, ethanol, and various solvents.

4：Experimental Procedures and Operational Workflow:

For solvothermal synthesis, reactants were mixed in H2O:ACN:DMF and heated. For sonochemical synthesis, reactants were sonicated in water with pyridine. Luminescence sensing involved suspending Zn-CP in ethanol and adding TNP solutions.

5：Data Analysis Methods:

Data were analyzed using FT-IR for functional groups, PXRD for phase purity, TGA for thermal stability, SEM for morphology, luminescence spectra for sensing performance, and UV-Vis for absorption. Quenching efficiency was calculated using (I0 - I)/I0 * 100%, and Stern-Volmer plots were used for sensitivity analysis.
