Squaric acid as a versatile compound in the design of molecular solids
… coordination modes of the squarate and also its acid properties were envisaged. In a systematic way, using either a coordinative or a hydrogen-bonding motif, three classes of compounds have been synthesized and characterized by single-crystal X-ray diffraction: 1. Hydrogen-bonded systems based on …

Characteristics and Performance of Novel Squarylium Dyes as Fluorescent Probes for the Analysis of Proteins and Viruses by CE-LIF
… variations in placement and number of carboxylic acid residues, as potential fluorescent probes for proteins and viruses. Bis-SQ-4d, which contains a double squaric acid center, was found to be a successful noncovalent label for human serium albumin (HSA), myoglobin, transferrin, trypsinogen, and …

Novel near-infrared absorbing dyes
… bands at about 800nm were obtained by reacting squaric acid with 2,2-disubstituted dihydroperimidines. The first dyes of this type possessed poor organic solvent solubilities but, through modification of the 2,2-substituents of the dihydroperimidines it was possible to obtain squarylium dyes …

CxNy-materials from supramolecular precursors for “All-Carbon” composite materials
… C₂N was explored, based on organic crystals from squaric acid and urea. The respective C₂N carbon with an unusual sheet-like morphology could be synthesized by carbonization of the crystals at 550 °C. With this precursor system, also microporous C₂N carbon with a BET surface area of 865 m²/g was …
