AI Article Synopsis

  • The compound studied is a copper complex with the formula [Cu(C14H12N2)2](C4HO4) x 0.5H2O, where copper is coordinated to two bidentate dmphen ligands.
  • The structure features a distorted tetrahedral geometry around the Cu(I) center, and the squarate ions form stable dimers connected by strong hydrogen bonds.
  • The overall crystal stability is enhanced by a network of C-H...O hydrogen bonds and pi-pi interactions, creating a three-dimensional structure.

Article Abstract

In the crystal structure of the synthetically prepared title compound, [Cu(C14H12N2)2](C4HO4) x 0.5H2O or [Cu(dmphen)2](HSq) x 0.5H2O (dmphen is 2,9-dimethyl-1,10-phenanthroline or neocuproine and HSq is hydrogen squarate), the Cu(I) centre has distorted tetrahedral coordination geometry comprised of four N atoms from two bidentate dmphen ligands. The squarate monoanions form a ten-membered dimer, graph set R(2)(2)(10), linked by two strong intermolecular O-H...O hydrogen bonds. These squarate dimers are linked into chains that propagate along the [100] direction. An extensive three-dimensional network of C-H...O hydrogen bonds and pi-pi interactions is responsible for stabilization of the crystal structure.

Thermoplastics, while advantageous for their processability and recyclability, often compromise thermochemical stability and mechanical strength compared to thermosets. Addressing this limitation, we introduce an innovative approach employing reversibly cross-linked polymers, utilizing squaramide moieties to reconcile recyclability and robustness. Herein, we detail the synthesis of supramolecularly cross-linked polysquaramides through the condensation polymerization of diethyl squarate with primary and secondary diamines.

Separating deuterium from hydrogen isotope mixtures is of vital importance to develop nuclear energy industry, as well as other isotope-related advanced technologies. As one of the most promising alternatives to conventional techniques for deuterium purification, kinetic quantum sieving using porous materials has shown a great potential to address this challenging objective. From the knowledge gained in this field; it becomes clear that a quantum sieve encompassing a wide range of practical features in addition to its separation performance is highly demanded to approach the industrial level.

(1) Background: carbonic anhydrases (CAs) are attractive targets for the development of new anticancer therapies; in particular, CAs IX and XII isoforms are overexpressed in numerous tumors. (2) Methods: following the tail approach, we have appended a hydrophobic aromatic tail to a pharmacophore responsible for the CA inhibition (aryl sulfonamide, coumarin). As a linker, we have used squaramides, featured with strong hydrogen bond acceptor and donor capacities.

The population imbalance between nuclear singlet states and triplet states of strongly coupled spin-1/2 pairs, also known as nuclear singlet order, is well protected against several common relaxation mechanisms. We study the nuclear singlet relaxation of C pairs in aqueous solutions of 1,2-C squarate over a range of pH values. The C singlet order is accessed by introducing O nuclei in order to break the chemical equivalence.
