ABSTRACTThis paper discusses recent progress made in developing an advanced sp2 carbon-based materials that can be produced by wet coating as a thin layer and processed to form highly ordered arrays of Graphene Nanoribbons (GNRs) that attach to the substrate on edge with their planes parallel to each other. The fabrication method is based on carbonization of organic molecules spatially preordered in crystalline film on the substrate. This material, named Ribtan, can be used to fabricate GNRs films over large areas that exhibit a very smooth film surface and can form strong covalent bonds to the substrate. The width (film thickness) of Ribtan GNRs can be controlled precisely down to a few nanometers. We demonstrated advantage of Ribtan material for application in supercapacitors as well as feasibility for use in transparent electrodes, solid tribological coatings, and thin film transistors.

Background: The preparation and use of pyridinyl alcohols as ligands showed incredible increment in the past three decades. Important property of pyridinyl alcoholato ligands is their strong basicity, which is mainly due to the lack of resonance stabilization of the corresponding anion. This strongly basic anionic nature gives them high ability to make bridges between metal centers rather than to bind to only one metal center in a terminal fashion. They are needed as ligands due to their ability to interact with transition metals both covalently (with oxygen) and hemilabile coordination (through nitrogen). Objective: The review focuses on the wide application of α-pyridinyl alcohols, α,α’-pyridine diols, α- bipyridinyl alcohols, and α,α’-bipyridine diols as structure motifs in the preparation of important organic molecules which is due to their strongly basic anionic nature. Conclusion: It is clear from the review that in addition to their synthetic utility in the homogeneous and asymmetric catalytic reactions, the preparation of the crown ethers, cyclic and acyclic ethers, coordinated borates (boronic esters), pyridinyl-phosphine ligands, pyridinyl-phosphite ligands, and pyridinyl-phosphinite ligands is the other broad area of application of pyridinyl alcohols. In addition to the aforementioned applications they are used for modeling mode of action of enzymes and some therapeutic agents. Their strongly basic anionic nature gives them high ability to make bridges between metal centers rather than to bind to only one metal center in a terminal fashion in the synthesis of transition metal cluster complexes. Not least numbers of single molecule magnets that can be used as storage of high density information were the result of transition metal complexes of pyridinyl alcoholato ligands.
