Competing phenol–imidazole and phenol–phenol interactions in the flexible supramolecular environment of N,N′-bis(3-imidazol-1-ylpropyl)naphthalenediimide causing domain expansion

Spectroscopic and crystallographic studies on cocrystals of N,N′-bis(3-imidazol-1-yl-propyl)naphthalenediimide (L) with a series of phenolic compounds have revealed that competition to form phenol–imidazole and phenol–phenol synthons causes domain expansion.

Oxime synthons in the salts and cocrystals of quinoline-4-carbaldoxime for non-covalent synthesis

Synthons in the cocrystals and salts of quinoline-4-carbaldoxime with acids are discussed.

Solvent and anion facilitated conformational changes in benzylamine substituted thiazolamine

Solvent and anion guided conformational adjustments in the syn–anti–syn form of N,N′-(1,4-phenylene-bis(methylene))-bis(5-methylthiazol-2-amine) and the utility of nitrate ions in stabilizing the anti–anti–anti form are established.

A study on fluoride detection and assembly of hydroxyaromatic aldoximes caused by tetrabutylammonium fluoride

Different assemblies formed by the interactions of tetrabutylammonium fluoride with hydroxy-aromatic oximes show characteristic optical properties.

A modular approach for molecular recognition by zinc dipicolinate complexes

Recognition of 4-nitrophenol guest molecules by stacking and H-bonding interactions with a 4,4′-bipyridinium zinc dipicolinate host was found and investigated in detail.

Cyclic aromatic imides as a potential class of molecules for supramolecular interactions

Prospects of stacking interactions of imides beneficial to generation of new soft materials are projected by analysing examples of primary building blocks that provide a basis for understanding at the molecular level.

Study on divalent copper, nickel and zinc model complexes for fluoride ion detection

A series of mononuclear hydroxyaromatic oxime metal complexes were synthesized for detection of fluoride ion and shown that the spectral signals of such complexes depend on the electronic configuration of the metal ion.
