An azobenzene based iminopyridine ligand 1 has been synthesized by a condensation reaction between N,N-dimethyl-4,4′-azodianiline and 2-formylpyridine. The complexation of the with ZnCl2 afforded tetrahedral neutral zinc metal complex (2) formulated as [(Azo-Imino-Py)ZnCl2]. crystal structure analysis indicates formation tetracoordinated zinc(II) ion expected geometry. In solid state, 2D supramolecular architecture reinforced π–π stacking hydrogen bonding is observed. UV–visible...
Cocrystallization of 7,7′,8,8′-tetracyanoquinodimethane radical anion (TCNQ–•) and 3-methylpyridinium-1,2,3,5-dithiadiazolyl cation (3-MepyDTDA+•) afforded isostructural acetonitrile (MeCN) or propionitrile (EtCN) solvates containing cofacial π dimers homologous components.

Photocatalytic hybrid systems were realized by associating bismuth vanadate nanostructured thin films with anchored organic dyes. The quantum chemical calculations and computer modelling may explain the charge transfer behaviour occurring in systems.
This paper presents the linear and nonlinear optical (NLO) properties of two donor–acceptor organic materials, namely, N,N-dimethyl-4-((E)-(4-((E)-((5-phenylthiophen-2-yl)methylene)amino)phenyl)diazenyl)aniline A (E)-4-((E)-(4-nitrophenyl)diazenyl)-N-((5-phenylthiophen-2-yl)methylene)aniline B.
