Background: Although the synthesis of α-hydroxymethylenebisphosphonic acids (dronic acids) and derivatives by reaction of the corresponding carboxylic acids (or its derivatives) with P-reagents, such as phosphorus trichloride, phosphorous acid and phosphoryl chloride formed the subject of many studies, in most cases, the selection of the P-reagents, their ratio, and the conditions (solvent and temperature) were not optim Read More

Background: Polymer-peptide/protein conjugates immobilized on surface have gained considerable attention, mostly due to their broad scope of applications in biomedical fields. To optimize their properties, the combined knowledge of polymer chemistry and biochemistry has to be applied. Method: The main methods to obtain such surfaces involve “grafting to” or “grafting from” of polymeric linkers with subsequent attach Read More

Background & Objective: Fullerene-containing liquid crystals have attracted considerable attention in a wide variety of fields including materials science, supramolecular chemistry, bioscience, nanoscience and nanotechnology based on the outstanding photophysical and electrochemical properties of fullerenes. This review describes the recent and significant developments of fullerene-containing liquid crystals which displ Read More

Background: Rearrangements as an important class of organic reactions could provide structural isomers of the original molecules. They can transform precursors into favorable difficult-to-make products. One of the important synthetic tools in modern organic chemistry is the Smiles rearrangement and its different variants, which have diverse applications in organic chemistry. Objective: The Smiles rearrangement is Read More

Background: Nitrogen containing heterocycle is one kind of the most important heterocycle. Among them, 1,2,4-triazolo[3,4-α]pyridine is a classic five member heterocycle fused six member heterocycle. 1,2,4-Triazolo-[3,4-α ]pyridine scaffold has been widely used in building blocks for drugs, pesticides and other fields. Method & Objective: This review will highlight the early and recent work on the synthesis methods of diversity Read More

Background: Dye-sensitized solar cells have received attention recently for efficient converting sunlight to electricity. Organic dyes provide a feasible alternative due to the practical advantages, such as facile structure tuning, easy synthesis process, and low cost. Organic sensitizers are generally designed to link the electron donor and the electron acceptor. When light irradiated on the dyes, these dipolar molecules indu Read More
