Surface-Engineered Hydrophobic Porous Organic Polymer for Enhanced SERS Detection of Plasticizers

Popis výsledku v původním jazyce

Surface-enhanced Raman spectroscopy (SERS) has emerged as a powerful analytical tool for the detection of plasticizers, offering ultrasensitive fingerprint recognition, convenient operation, and minimal interference from water. Herein, a gold-anchored and thiol-functionalized superhydrophobic porous organic polymer (Au@POP-SH) for the rapid, sensitive, and selective detection of Phthalic acid esters (PAEs) is developed. Au@POP-SH is synthesized from POP-OH using N,N-dimethyl(thiocarbonyl) chloride under solvothermal conditions, enabling the anchoring of gold nanoparticles onto thiol groups with significant textural parameters. The resultant Au@POP-SH efficiently detects a broad range of phthalic acid esters demonstrating remarkable sensitivity with a lowest detectable concentration of 7.33 x 10(-13) m for dibutyl phthalate (DBP) through SERS. It should be noted that Au@POP-SH exhibited excellent stability and a rapid, highly sensitive, and specific approach for SERS-based phthalic acid ester detection arises from the synergy between AuNPs and POP-SH, enabling hot spots, analyte adsorption and pi-pi interactions. Furthermore, advanced density functional theory (DFT) calculations reveal the interaction mechanism between Au@POP-SH and phthalic acid esters, enabling selective detection of dimethyl phthalate (DMP) and DBP. Multivariate analysis with spectral preprocessing improves SERS quantification, and partial least squares models show strong correlation (R-2 = 0.9992) confirming that SERS combined with chemometric methods offers a robust analytical strategy for plasticizer detection.
