“…The porphyrin-base, namely: 5-(3-hydroxy-phenyl)-10,15,20-tris-(3-methoxy- phenyl)-porphyrin (OH-3MeOPP), was synthesised by using a multicomponent reaction, involving two different substituted aldehydes, 3-methoxybenzaldehyde and 3-hydroxybenzaldehyde, as it was recently reported in [ 64 ]. The mixture of the six obtained compounds was subjected to TLC analysis performed on silica gel 60 F Merck plates and, after elution with chloroform/dichloromethane/diethyl ether (5:5:1, v / v / v ), the peak at R f = 0.909 was proven to be the desired OH-3MeOPP A 3 B porphyrin.…”

Porphyrins are versatile structures capable of acting in multiple ways. A mixed substituted A3B porphyrin, 5-(3-hydroxy-phenyl)-10,15,20-tris-(3-methoxy-phenyl)-porphyrin and its Pt(II) complex, were synthesised and fully characterised by 1H- and 13C-NMR, TLC, UV-Vis, FT-IR, fluorescence, AFM, TEM and SEM with EDX microscopy, both in organic solvents and in acidic mediums. The pure compounds were used, firstly, as sensitive materials for sensitive and selective optical and fluorescence detection of hydroquinone with the best results in the range 0.039–6.71 µM and a detection limit of 0.013 µM and, secondly, as corrosion inhibitors for carbon–steel (OL) in an acid medium giving a best performance of 88% in the case of coverings with Pt-porphyrin. Finally, the electrocatalytic activity for the hydrogen and oxygen evolution reactions (HER and OER) of the free-base and Pt-metalated A3B porphyrins was evaluated in strong alkaline and acidic electrolyte solutions. The best results were obtained for the electrode modified with the metalated porphyrin, drop-casted on a graphite substrate from an N,N-dimethylformamide solution. In the strong acidic medium, the electrode displayed an HER overpotential of 108 mV, at i = −10 mA/cm2 and a Tafel slope value of 205 mV/dec.

“…The five isosbestic points that are displayed on the UV-Vis spectra (at 375 nm, 535 nm, 566 nm, 612 nm, and 630 nm) demonstrate the existence of some intermediate species between the AuNPs and azaporphyrin that affect the entire macrocycle. The synergistic effect between AuNPs and porphyrins generally provides an enlarged absorption domain [62][63][64] that is useful for improving optical applications. In the formed complex, the gold nanoparticles that are negatively surface charged easily interact with the partially positively charged nitrogen atoms of the porphyrin core in the porphyrin base, or with the diprotonated porphyrin that forms in the acid medium.…”

Monitoring antibiotic retention in human body fluids after treatment and controlling heavy metal content in water are important requirements for a healthy society. Therefore, the approach proposed in this study is based on developing new optical sensors using porphyrin or its bifunctional hybrid materials made with AuNPs to accomplish the accurate detection of chloramphenicol and cobalt. To produce the new optical chloramphenicol sensors, 2,7,12,17-tetra-tert-butyl-5,10,15,20-tetraaza-21H,23H-porphine (TBAP) was used, both alone in an acid medium and as a hybrid material with AuNPs in a water–DMSO acidified environment. The same hybrid material in the unchanged water–DMSO medium was the sensing material used for Co2+ monitoring. The best results of the hybrid materials were explained by the synergistic effects between the TBAP azaporphyrin and AuNPs. Chloramphenicol was accurately detected in the range of concentrations between 3.58 × 10−6 M and 3.37 × 10−5 M, and the same hybrid material quantified Co2+ in the concentration range of 8.92 × 10−5 M–1.77 × 10−4 M. In addition, we proved that AuNPs can be used for the detection of azaporphyrin (from 2.66 × 10−5 M to 3.29 × 10−4 M), making them a useful tool to monitor porphyrin retention after cancer imaging procedures or in porphyria disease. In conclusion, we harnessed the multifunctionality of this azaporphyrin and of its newly obtained AuNP plasmonic hybrids to detect chloramphenicol and Co2+ quickly, simply, and with high precision.

“…The hybrid 5-COOH-3MPP-k-carrageenan-AuNPs material was obtained in the same manner as described in [25] by mixing together 5-(4-carboxyphenyl)-10,15,20-tris-(4-methylphenyl)-porphyrin and k-carrageenan in molar ratio 1:10 in DMF and then adding 36.2 mL of gold colloidal solution (c = 6.91 × 10 −4 M) to 30 mL hybrid solution in order to obtain the final molar ratio porphyrin: k-carrageenan: AuNPs = 1:10:10. The gold nanoparticles of around 10-15 nm in diameter were obtained by reducing tetrachloroauric acid with citrate in hot water [41,42].…”

The multifunctionality of an A3B mixed-substituted porphyrin, namely 5-(4-carboxyphenyl)-10,15,20-tris(4-methylphenyl)porphyrin (5-COOH-3MPP), was proven due to its capacity to detect procaine by different methods, depending on the polymer matrix in which it is incorporated. The hybrid nanomaterial containing k-carrageenan and AuNPs (5-COOH-3MPP-k-carrageenan-AuNPs) was able to optically detect procaine in the concentration range from 5.76 × 10−6 M to 2.75 × 10−7 M, with a limit of detection (LOD) of 1.33 × 10−7 M. This method for the detection of procaine gave complementary results to the potentiometric one, which uses 5-COOH-3MPP as an electroactive material incorporated in a polyvinylchloride (PVC) membrane plasticized with o-NPOE. The detected concentration range by this ion-selective membrane electrode is wider (enlarged in the field of higher concentrations from 10−2 to 10−6 M), linearly dependent with a 53.88 mV/decade slope, possesses a detection limit of 7 × 10−7 M, a response time of 60 s, and has a certified stability for a working period of six weeks.
