“…Several fluorometric procedures are widely used, e.g. for Ca 2+ [37], Hg 2+ [38], Cd 2+ and Pb 2+ ions in 10 -7 M concentration [39], and for Hg 2+ and Fe 2+ by fluorescence resonance energy transfer [40]. In HPLC techniques heavy metal ions can be determined by porphyrins [28], as well as nickel and vanadium ions from the crude oils too [7].…”

We investigated the UV-Vis absorption, singlet-1 and singlet-2 fluorescence, as well as the formation of several metalloporphyrins from equilibrial and kinetic aspects in aqueous solution. Among these complexes were numerous typical out-of-plane and several in-plane metalloporphyrins, and between the two categories, a few border-line cases. On the basis of our results, we have complemented the categorization introduced by Barnes and Dorough for the metalloporphyrins. According to our observations, also in metalloporphyrins, the distortion, i.e., the planarity or nonplanarity of the macrocycle, is basically responsible for the spectral characteristics, while the electronic structure of metal center is a secondary factor, with a considerable importance mainly in the in-plane complexes. The type of complexes can be spectrophotometrically determined on the basis of their UV-Vis absorption and fluorescence spectra. Beside the spectral and photophysical effects of metalation, also those of the structural distortions were studied, which can originate also from metalation, protonation or overcrowded peripheral substitution of the free-base porphyrins, as well as from the axial ligation of metalloporphyrins. Our observation may be useful for different spectrophotometric analytical detection and determination methods, e.g. size-selective metal detection using free-base porphyrins (or other ringed chelate ligands), as well as the determination of Lewis bases as potential axial ligands, using metalloporphyrins.

“…The results presented show how effective a unimolecular receptor/sensor system can be when used in combination with chemometric tools. Hence, therapeutic chromophore 1 competes efficiently with multiple-dye integrated sensors or devices, multichannel sensors and array based sensors, and takes analytical device miniaturization6789101112131415161718192021222324252627282930313233343536373848495051525354555657585960 a step further with easy accessibility and diversification using an already existing concept of pattern generation and chemometric analysis.

The efficacy of a miniaturized unimolecular analytic system is illustrated. The easily accessible therapeutic chromophore “temoporfin”, which responds differentially to bound metals at multiple wavelengths of Q-band absorption using chemometric analysis, expeditiously detects and discriminates a wide range of metals regarded as priority pollutants in water and hence may also be used for diagnosis of medically relevant metals in human urine. The molecule was further investigated as an electronic logic device, e.g. keypad lock device, to authorize multiple highly secure chemical passwords for information protection.

“…The technology of controlling water quality with very high sensitivity has received much attention for the area of power generation, because even slight amounts of contaminations such as metal salts and small molecules have the potential to cause a very serious accident . As Na + is one of the most abundant ions in nature, Na + is the important detection target in the analysis of supply water and cooling water in power plants.…”

Ultra-High-Sensitive Extraction-Photometric Determination of Sodium Ion Using Flow Injection Analysis with a Chromogenic Calix[4]arene Derivative and a Laser Interferometric Photothermal Detector

et al. 2012

View full text Add to dashboard Cite

A novel flow injection analysis (FIA) system for ultra-high-sensitive determination of Na(+), which involves laser interferometric photothermal equipment as the detector, was designed using a proton-dissociable chromogenic calix[4]arene derivative with a dinitrophenol moiety as the extraction-photometric reagent. The chromogenic calix[4]arene derivative showed an excellent extractability toward Na(+), which reflected the cation-complexing property of the tetraethyl ester derivative of calix[4]arene. As the calibration graph of the Na(+) concentration could be successfully obtained at the nanomolar level by this method, the proposed FIA system was found to be promising for highly sensitive determination of Na(+) in very dilute samples such as supply water and cooling water in power plants.
