In 1990, a new research group was constituted in the Institute of Chemistry, University of Wrocław. The team led by D.Sc. Lechosław Latos-Grażyński focused on the synthesis of novel macrocycles from the porphyrin family and their coordination abilities. The article describes the origins, development, and 30 years of activity of Porphyrin and Metalloporphyrin Chemistry Group.

The presented article describes the role of community of indigenous microorganisms occurring in the Kupferschiefer black shale in elements mobilization from fossil organic matter of the deposit. The short description of metalloorganic compounds and metalloporphyrins extracted from black shale was presented as well as the characterization of indigenous microorganisms. The processes of fossil organic matter colonization, biofilm development and elements mobilization accompanying bacterial growth was summarized.

Optical chemical sensors enlarge the definition of a classical chemical sensor; they present results in two-dimensional (2D) or three-dimensional (3D) aspect. They can determine parameters of micro and macro scale objects without using a lot of electronic equipment. This article is focused on sensors based on porphyrin derivatives and europium complexes, being the most frequently used substances sensitive to oxygen concentration, pressure and temperature changes. Along with the presentation of characteristics of substances employed to sensors’ construction, also the general principle of luminescent sensors operation, composition and operation range of selected mono- and bifunctional luminescent sensors are described; moreover the selected achievements, such as the “traffic light” sensor are shown.

Modification of Tetraphenylporphyrin Ring in Manganese(III) Complexes - Theoretical Description of the Influence on Their Physicochemical Properties

Metalloporphyrins are known to be efficient catalysts in oxidation of hydrocarbons. To understand a mechanism of oxidation processes de tailed knowledge of the electronic and structural parameters of these systems is required. Here, atomic parameters calculated by means of DFT method for the selected manganese porphyrins are correlated with experimental redox potential. The results of calculations carried out for systems with modification in phenyl substituents showed that charge of porphyrin ring and charge of axial ligand are good theoretical descriptors of effect introduced by the substituent. These descriptors correlate (R2 = 0.97) with experimental value of redox potential of the MnIII/MnII system.

Omówiono szerokie możliwości wykorzystania porfiryn jako elementów aktywnych chemi- i bioczujników. Porfiryny to odgrywające olbrzymią rolę w przyrodzie związki makro cykliczne, których analityczne właściwości można modyfikować przez odpowiedni dobór podstawników makrocyklicznego pierścienia lub metalu wprowadzonego do wnętrza pierścienia. Zaprezentowano wykorzystanie i dalsze możliwości zastosowania porfiryn i metaloporfiryn w czujnikach zol-żelowych służących do oznaczania jonów metali, anionów, gazów, pH, związków organicznych oraz związków biologicznie czynnych.

The porphyrins, naturally occuring macrocyclic compounds have in the last several years, gained increasing interest in chemistry of the sensors. The porphyrins play a pivotal role in many natural processes and their properties can be modified by the change of the substituents of the macrocyclic ring or by the kind of the metal inserted into the ring. This review based on original literature references, presents application of the porphyrin and metalloporphyrin sensors to detection of metal cations, anions, gases, pH, organic compounds and biomolecules.
