A novel eight-coordinated dinuclear Ca(II) complex, [Ca2(L)2(H2O)10]·H2O (L = 4-formylbenzene-1,3-disulfonate-3-pyridinecarboxylic hydrazone) (1), was synthesized by the reaction of 3-pyridinecarboxylic hydrazide, disodium 4-formylbenzene-1,3-disulfonate, and Ca(ClO4)2·4H2O in ethanol-water solution (v:v = 3:1) at 50 ◦C. Complex 1 was characterized by elemental analysis, IR, 1H-NMR, 13C-NMR, an...

A new class of platinum(ii) terpyridine complexes with a phosphole-derived bridging alkynyl ligand have been prepared. The X-ray crystal structure of complex 2 has been determined, and reveals a polymeric zig-zag chain structure with the existence of π-π stacking interactions. The photophysical properties have also been studied, with 3MLCT/3LLCT phosphorescence exhibited in degassed CH2Cl2; the...

Ultra-thin two-dimensional (2D) materials have attained huge interest for biosensing applications because of their strong electrostatic coupling with target molecules such as spike proteins and DNA. One 2D material is graphene, which extremely thin flexible has a non-covalent interaction the supporting constructs needed to detect biomolecules. This work aimed develop way efficiently functionali...

In the crystal structure of the title salt, C10H16N3O(+)·C7H5O2 (-), the cations and anions are linked to each other via N-H⋯O hydrogen bonds, forming infinite chains running along [010]. The crystal structure also features C-H⋯O and π-π stacking inter-actions, which assemble the chains into supra-molecular layers parallel to (100). The π-π stacking inter-actions are observed between the pyridi...

The crystal structure of the title compound, C8H10N2O3S, displays predominant C-H⋯O hydrogen-bonding and π-π stacking inter-actions. The hydrogen bonds are between the O atoms of the sulfonyl group and H atoms on methyl groups. The π-π stacking inter-actions occur between adjacent aromatic rings, with a centroid-centroid distance of 3.868 (11) Å. These inter-actions lead to the formation of cha...

Fluid interfaces provide an advanced platform for directed self-assembly of organic composites and formation supramolecular polymers (SPs). Intermolecular interactions govern the polymerization processes, with hydrogen bonding (H-bonding) as a key interaction in chemistry biology. Two purposefully designed supra-amphiphiles assessing role H-bonding were their (SP) at air/water interface was com...

Azobenzene macrocycles were designed for switchable π-stacking interaction. After efficient preparation and characterization of azobenzene macrocycles containing electron rich as well as electron poor elements a dimeric analogue was synthesized, which formed reversibly 3D-networks. Gel formation was observed with aromatic solvents representing the first example of this type based on switchable ...
