“…Researchers reported porphyrin films with various functional groups to detect H 2 S gas at room temperature with [ 22 , 23 , 24 , 25 , 26 , 27 ] using optical waveguide but the results and experimental performance are deficient in consistence. Therefore, in this work, we consolidate the experimental performing conditions including film width and thickness that was controlled by film fabrication velocity and solution concentration; laser light wavelength (670 nm), gas concentration was also unified to keep the only possible different variable is the influence of functional groups.…”

Substituent effect on optical gas sensing performance in porphyrin-based optical waveguide detection system was studied by molecular dynamics simulation (MDS), absorption/emission spectrum analysis, and optical waveguide (OWG) detection. The affinities of porphyrin with seven types of substituents (–H, –OH, –tBu, –COOH, –NH2, –OCH3, –SO3−) on para position of meso-phenyl porphyrin toward gas molecules in adsorption process were studied in different size of boxes with the same pressure and concentration. Analyte gases (CO2, H2S, HCl, NO2) were exposed to porphyrin film in absorption spectrophotometer, and in OWG with evanescent field excited by a guiding laser light with 670 nm wavelength. The extent of interaction between host molecule and the guest analytes was analyzed by the number of gas molecules in vicinity of 0.3 nm around substituents of porphyrin molecules. Optical waveguide results reveal that sulfonate porphyrin is mostly responsive to hydrochloride, hydrosulfide gas and nitrogen dioxide gases with strong response intensity. Molecular dynamics and spectral analysis provide objective information about the molecular state and sensing properties. Molecular rearrangements induced by gas exposure was studied by spectral analysis and surface morphology before and after gas exposure taking hydrosulfide gas as an example. Film-gas interaction mechanism was discussed in terms of each gas and substituent group characters.

“…Este MOF, quando comparado com outros materiais, tais como compósitos rosamina/TiO 2 [37] e rosamina/SiO 2 /TiO 2 [38], apresenta valores de t 50 (tempo de decaimento de 50% do valor máximo de luminescência) inferiores aos reportados, entre 1-8 min para uma gama de concentração de NO 2 entre 5-500 ppm. Outro exemplo com elevada sensibilidade e limite de deteção mais baixo (até 10 ppb) e cuja deteção é realizada por alterações no espectro de absorção é o de um filme fino preparado a partir de 5,10,15,20-tetraquis(4-butilfenil)porfirina [39].…”

Porphyrin-based Optical Sensors for Environmental and Biomedical Applications. Porphyrins are tetrapyrrolic macrocycles, which are endowed with excellent photophysical and electrochemical properties. However, porphyrins often exhibit low stability and fluorescence quenching under physiological conditions, thus limiting their application in biomedical and environmental sciences. To overcome these limitations, porphyrins can be incorporated into metalorganic frameworks (MOFs), opening new avenues for high-performance materials that integrate the specific physicochemical properties of porphyrins and MOFs, with a wide range of applications, from selective storage of gases, catalysis, to detection of different chemical substances. In this article several examples of porphyrin-based optical sensors are described, addressing the MOFs preparation to porphyrinic MOFs. The detection mechanisms and possible practical applications of the developed systems will also be discussed.

“…Optical waveguide spectroscopy is known to be a powerful tool for the detection of optical materials because of its good selectivity, high sensitivity, and simultaneous detection of absorption and emission spectra [ 22 ]. It has also been applied to study optical materials and development of an optical sensors [ 23 , 24 , 25 , 26 , 27 ]. In this work, we established an optical measurement system including the synthesis of a fluorescent solvatochromic resin using the Suzuki–Miyaura cross-coupling reaction and the analysis of its specific photophysical properties as the identification of the synthesized compound on the resin surface.…”

We have established a novel analytical method for solvent polarity on resin surface by combining the synthesis of fluorescent solvatochromic resin with optical waveguide spectrometry. The fluorescent solvatochromic resin was obtained via Suzuki–Miyaura cross-coupling between 4-iodobenzoic acid immobilized on Wang resin and 5-[4-(N,N-dihexylamino)phenyl]-2-thienylboronic acid N-methyl-iminodiacetic acid (MIDA) ester. The optical waveguide spectrometry studies on the resin showed a strong fluorescent solvatochromism in various organic solvents.
