Opis:: The pentafluorosulfanyl (-SF₅) moiety is a lesser known and underutilized functional group that displays high electronegativity, chemical and thermal stability, and low surface energy, among other useful properties. As a substituent it is known for almost 60 years, however practical application of the unique -SF₅ group in various areas of chemistry has only recently picked up, mostly due to longstanding challenges associated with its synthetic accessibility. Most of the latest attention involving the use of -SF₅ has been in medicinal chemistry, but it has also started to feature much more frequently in functional materials design, especially in the area of optoelectronic materials. This review will describe polymers and macromolecules containing -SF₅ substituent which has been introduced mainly at the monomer stage.

Opis:: In the last decade molecular imprinted polymers (MIP) have gained great interest in the area of selective recognition various type substances. Scientific work in this field is carried out very intensively - the methods of synthesis are modified and improved, new types of hydride materials are created, as well as new reagents for synthesis. In this case, cyclodextrins (CD) and their analogues show good molecular recognition ability for its unique physical and chemical properties and suitable cavity structure. As a result, these supramolecular ligands can perform various functions in the MIP technology, and the resulting polymeric materials are characterized by high selectivity and binding specificity (recognition) of analytes structurally matched to the MIP cavity. Of particular importance is the fact that cyclodextrins enable the imprinting not only of low-molecular-weight biologically active compounds, but also of high-molecular molecules (proteins, peptides). The numerous hydroxyl groups available in cyclodextrins are active sites that can form different types of linkages. They can be cross-linked with one another, or they can be derivatized to produce monomers that can form linear or branched networks. This article provides a detailed review of MIPs based on CD and their application in the field of separation science and analytical chemistry in recent years. The discussion is grouped according to the different role of CD in MIPs, that is, functional monomer, carrier modifier, etc.

Opis:: Isocyanides are compounds with a triple bond between a nitrogen atom and a carbon atom. Thanks to this structure, there is an electron lone pair on the carbon atom, which allows these compounds to participate in many reactions in organic chemistry. Due to their properties and the number of reactions in which they can participate, this group has been applied in medicine. Both natural and synthetic isocyanides have antifungal, antibacterial, antimalarial, antiviral and anticancer properties. The reactions involving them allow for a much simpler and faster synthesis of many pharmaceuticals. In addition, these compounds have application properties, making it possible to obtain polymers. Despite the polymerization of these compounds raising many objections, many polymeric materials based on isocyanides have found applications both in science and in everyday life.

Opis:: The potential for expanding the variety of catalytic methods for carbon-carbon bond formation is being currently explored in many research centres all over the world. An increasing use of selected d-block metals as catalysts in the synthesis has brought new methods of functionalization of organic and organometallic compounds of great importance for development of polymer chemistry and organic chemical technology [5, 6]. This work describes very precise and controlled catalytic transformations as useful tools for the synthesis of new E-conjugated organic, organosilicon molecular and polymeric compounds. The combination of Suzuki-Miyaura coupling and silylative coupling reactions as a simple and efficient method is established for designing new E-stereoregular hybrid materials in the presence of well-defined transition metal (TM) catalysts. All presented compounds can be interesting precursors for a further functionalization that may significantly increase the possibility of their application in the design and synthesis of new functional materials.
