Abstract

A new compound, 1,3‐bis(4‐chlorophenyl)‐5‐(4‐chlorobenzyl)‐1,3,5‐triazinane, C22H20Cl3N3 (I), was synthesized, and its structure was determined by X‐ray diffraction, along with various spectroscopic methods, UV‐VIS, FT‐IR, NMR 1H and 13C. The crystal belongs to the monoclinic system with a=7.1503 (5) Å; b=12.9506(10) Å; c=21.9709 (16) Å; β=96.637(2)° and space group P21/c. Hirshfeld surface analysis and two‐dimensional fingerprint plots were used to quantify the interatomic interactions present in the crystal. The molecular structure of (I) was determined by DFT calculations using the BP86‐D functional and a TZP basis set. The geometry optimizations and vibrational frequencies were calculated, and Natural atomic orbital charges were investigated using NBO 6.0 program. [ABSTRACT FROM AUTHOR]

Abstract

This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution license (http://creativecommons.org/licenses/by/4.0/).; International audience; Two arylene-cyanovinylene isomers formed by a phenyl unit substituted in para or meta positions by two cyanovinylene-methylthiophene were synthesized. Their main physicochemical properties were studied in order to point out the influence of the nature of the substitution (para vs meta) of the central phenyl unit on the electronic properties of the two isomers. The anodic electropolymerization of the two compounds was also studied with a main emphasis on the electrochemical behavior of the derived polymers showing that the specific behavior of the para-substituted isomer is maintained in its polymer leading to a polymer with a lower bandgap (1.95 eV) than the polymer obtained from the meta-substituted isomer (2.16 eV).

Abstract

In the title compound, C(16)H(12)Cl(2)O(2), the dichloro-phenyl and methoxy-phenyl groups are linked by a prop-2-en-1-one group. The C=C double bond is trans configured. The mol-ecule is not planar, as can be seen from the dihedral angle of 6.21 (7)° between the planes of the two rings. The crystal structure can be described by two types of crossed layers which are parallel to (110) and (10).
