Two new square planar Cu(II) and Ni(II) complexes, [CuL 1 (NCO)] (1) and [NiL 2 (N 3 )] (2) have been synthesized with two different tridentate N 2 O donor Schiff base ligands L 1 H (1:1 condensation product of benzoylacetone and 2-diethylaminoethylamine) and L 2 H (1:1 condensation product of benzoylacetone and 2-dimethylaminoethylamine), respectively. Both the complexes 1 and 2 have been characterized by elemental analysis, IR, UVVis spectroscopy, room temperature magnetic susceptibility measurement, electrochemical, thermal, and single crystal X-ray diffraction studies. Structural studies reveal that in both the complexes metal centers have square planar environment with N 2 O donor set of Schiff base ligands and terminal pseudohalide anions (isocyanate for 1 and azide for 2) at four coordination sites of square plane.

“…Figure 9 presents the optical images of Ppy, P(py‐ co‐ EDOT) and PEDOT films deposited potentiostatically at 1.05, 1.3, and 1.3 V. The Ppy film shows yellow–green color at −0.8 V and blue–violet at 0.8 V [Figure 8(a)] 37. The color of doped and dedoped PEDOT film are light blue (1.0 V) and dark blue (−0.8 V), respectively [Figure 8(c)] 13. It is interesting that the electrochromic phenomena of P(py‐ co‐ EDOT) film is quite different from those of two individual homopolymers, At an applied potential of −0.6 V, the film shows a amaranth color and passes to brown at −0.3 V. With the increase of potential, P(py‐ co‐ EDOT) film turns into dark gray (0.4 V) and light blue at 0.8 V [Figure 8(b)].…”

“…Spectroelectrochemistry is a powerful way to investigate the optical properties of a electrochromic conducting polymer under potential change, which also provides information on the electronic structure of the conducting polymer 13, 27.

“…Fine tuning of the electrochromic properties of the conducting polymers could be achieved by using three main strategies: (1) the derivatization of monomer structure of prior to polymerization, (2) copolymerization with different monomers, and (3) preparation of hybrid materials 12. Among these, copolymerization is a promising method to obtain better electrochromic properties than the homopolymers 13. Recently, many works have been focused on the electrochemical copolymerization of EDOT with different monomers to improve the electrochromic properties of PEDOT 14–16…”

A copolymer based on pyrrole and 3,4-ethylenedioxythiophene (EDOT) was electrochemically synthesized on an indium tin oxide ITO/glass electrode in acetonitrile containing lithium perchlorate (LiClO 4 ). The resultant copolymer is characterized via cyclic voltammetry, FTIR, SEM, XPS, and spectroelectrochemical analysis. The spectroelectrochemical analysis revealed the copolymer film has distinct electrochromic properties with respect to the homopolymers, and presented four colors (amaranth, brick red, dark grey, and light blue) under various applied potentials. For the copolymer in the neutral state, the calculated onset energy for the pp* transition (E g ) is 1.69 eV, and the absorption peak (k max ) is located at 508 nm. The maximum transmittance contrast (DT%) is 39.2% at 946 nm between the fully oxidized and intermediate(À0.4 V) states. Successive cyclic voltammograms and electrochromic switching experiment indicate the good stability of the copolymer because of the incorporation of EDOT units into the polypyrrole. It retains 81% of the original electroactivity and 71.8% of contrast after 2000 cycles.

“…Bond angles around the Mn(II) atom greatly deviate from expected values so the coordination geometry may be better described as a distorted pyramid rather than a distorted octahedron. (7) 1.0114 (8) Keto-Enol tautomerism of 1,3-diketones such as bzac has been extensively studied [14]. Neutron diffraction and accurate low temperature X-ray diffraction reveals that within the conjugated enol ring of bzac the C-C bond furthest from the phenyl ring is slightly longer than the C-C bond nearest the phenyl ring [15,16].…”

The complex (benzoato)benzoylacetonato(bipyridine)Mn(II) has been prepared and its crystal structure determined by X-ray diffraction methods. Benzoic acid, benzoylacetone (bzac) and 2,2 0 -bipyridine all chelate to Mn(II) to form a six coordinate complex. As bond angles around the Mn(II) atom greatly deviate from those expected for an octahedron, the coordination geometry may be described as distorted pyramidal with a bidentate carboxyl group occupying the apex of the pyramid. Although the Mn atom deviates by 0.550 Å from the enol ring plane of bzac, Mn-O distances [2.105(2) and 2.098(2) Å ] are normal. This suggests the existence of electrostatic interactions between Mn(II) and the bzac ligand.
