Films of three polymers, based on ethyl(hydroxyethyl)cellulose functionalized with protonated perichromic dyes, were used for anion sensing. The polymer functionalized with protonated Brooker's merocyanine acts as a chromogenic/fluorogenic system for the
Synthesis, characterization, and crystal structure analysis of Zn(II) and Cd(II) coordination compounds containing 4-((pyridin-4-ylmethylene)amino)phenol Schiff-base ligand

Zn(II) and Cd(II) coordination compounds containing 4-((pyridin-4-ylmethylene)amino)phenol ligands were synthesized and then characterized using spectroscopic techniques and single crystal X-ray crystallography. The molecular structure and crystal packing of these complexes, as well as the crystal packing of coordination complexes based on 4-substituted-1-(pyridin-4-yl)methanimine ligand, retrieved from Cambridge Structural Database (CSD), were investigated using structural, Hirshfeld surface analyses, and theoretical calculations. The crystal structure of these coordination complexes is governed by a combination of π···π stacking, C–H···π, O–H?N, and C–H···X hydrogen bonding interactions. This study provides further insight into the understanding of the role of weak non-covalent interactions in the crystal structure of group IIB containing Schiff-base ligand coordination compounds.

A series of symmetrical dimers bearing heterocyclic ring, a,w-bis-(4-pyridine-4-methylideneaminoxy) alkanes, were prepared and all the members are differed by the alkyl spacer length (CnH2n, where n = 6, 8, 10, 12). Differential scanning calorimetry and p

The oligomer of 4-(4-pyridylmethylideneimino)phenol was formed during oxidative polycondensation in aqueous alkaline medium using oxygen as the oxidant. Optimum conditions of the oxidative polycondensation and the main parameters of the process were found

Crystal engineering of coordination complexes has become an important research domain of modern inorganic chemistry. Herein, six Hg(ii) coordination compounds containing 2-((pyridin-3-ylmethylene)amino)phenol and 4-((pyridin-4-ylmethylene)amino)phenol lig
A new facile method for preparation of heterocyclic α-iminonitriles and α-oxoacetic acid from heterocyclic aldehydes, p-aminophenol, and sodium cyanide
Jursic, Branko S.,Douelle, Frederic,Bowdy, Katherine,Stevens, Edwin D.
, p. 5361 - 5365 (2007/10/03)
Very efficient, simple, and high yield procedures for the transformation of heterocyclic aldehydes into heterocyclic methylidene-p-hydroxyanilines, heterocyclic α-iminonitriles, and finally into heterocyclic α-oxoacetic acids were described. Considering that many of these compounds have biological activity, the synthetic methodology was optimized using readily available, inexpensive starting materials, and the purification of the product involved only simple crystallization.
