In this study, we report the synthesis of uniform and narrowly size-distributed ZnO nanoparticles with sizes of approximately 3 nm; the nanoparticles were prepared by means of organic-ligand-assisted hydrothermal conditions with various organic modifiers. The results obtained herein revealed that among the various functional groups tested (alcohols, aldehydes, carboxylic acids, and amines), only hexanol effectively controlled the nucleation and crystal growth of spherical ZnO nanoparticles. The use of hexanol also caused the surface of the ZnO particles to change from hydrophilic to hydrophobic, which would enhance the dispersion of these particles in polymer matrices, paints, cosmetics, and other organic application media.

Selected recent examples of coordination polymers (CPs) or metal-organic frameworks (MOFs) constructed from different multifunctional carboxylic acids with phenyl-pyridine or biphenyl cores have been discussed. Despite being still little explored in crystal engineering research, such types of semi-rigid, thermally stable, multifunctional and versatile carboxylic acid building blocks have become very promising toward the hydrothermal synthesis of metal-organic architectures possessing distinct structural features, topologies, and functional properties. Thus, the main aim of this mini-review has been to motivate further research toward the synthesis and application of coordination polymers assembled from polycarboxylic acids with phenyl-pyridine or biphenyl cores. The importance of different reaction parameters and hydrothermal conditions on the generation and structural types of CPs or MOFs has also been highlighted. The influence of the type of main di- or tricarboxylate ligand, nature of metal node, stoichiometry and molar ratio of reagents, temperature, and presence of auxiliary ligands or templates has been showcased. Selected examples of highly porous or luminescent CPs, compounds with unusual magnetic properties, and frameworks for selective sensing applications have been described.

Abstract Under hydrothermal conditions aqueous solutions of copper(II) sulfate (1) are reduced by means of saturated fatty acids with hydrogen at the α-atom to yield crystalline copper. In all cases carbon dioxide is liberated and lower fatty acids and ketones can be identified as reaction products. α-Hydroxy and α-aminocarboxylic acids proved to be very effective reducing agents towards 1. The yield of copper varied from 2 to 2.5 mol Cu per 1 mol of amino acid. The reaction of 1 is suppressed by sulfuric acid. The presence of hydrochlorid acid or chlorides leads to the precipitation of copper(I) chloride. The mechanisms of the decomposition of the various types of carboxylic acids is discussed. It was also possible to precipitate metallic copper by means of various proteins.
