An Influence of Copper Cation in the Complex on Structure of the Nanostructured Layers, Spectral and Electrocatalytic Characteristics of Langmuir-Schaeffer Films of Triphenylcorrole

“…It was shown earlier that metal free 5,10,15-triphenylcorrole in floating at the air-water interface layers and in LS films forms stable nanostructures of different types. [53,[63][64]66] In this work, the structure and properties of floating layers of copper 5,10,15-triphenylcorrole at the air-water interface in a wide range of initial surface coverage degrees (c face /c edge from 4/2.5 % to 93/58 %, Figure 2) were studied.…”

Compression Speed as a Parameter Changing the Dimensionality of Corrole Nanostructures in Layers at the Air-Water Interface

“…Note, that constants characterizing monolayer at a lower compression speed (v=2.3 cm 2 •min -1 ) are: (n) max =45, (D aggr ) const =11 nm, (c i-aggr ) const =75 %. [45] Thus, as compression speed of the layer increases, the maximum number of molecules It is shown that an increase in the compression rate leads to a decrease in the area per molecule in the aggregate (Figures 3a, 4) and a shift of the boundaries between layers of different types towards a lower degree of surface coverage (Δc face =1.9 % for face-on monolayers, Δc face =15.1 % for edge-on monolayers and Δc face =43.2 % for bilayer). At a high compression speed less stable layers with more dense nanoaggregates are formed.…”

“…[36,44] It was also shown that corroles at the air-water interface form nanostructured floating mono-and multilayers. [45,46] The effect of the initial surface coverage on the structure of the floating layers of 5,10,15-triphenylcorrol (H 3 [(ms-Ph) 3 Cor]) [45,46] and effect of temperature of subphase on the layers of (7,13-dimethyl-2,3,8,12,17,18-hexamethylcorrolato)manganese(III) [48] was demonstrated. It was revealed that triphenylcorrole is able to form J-aggregates in thin films.…”

“…It was revealed that triphenylcorrole is able to form J-aggregates in thin films. [45,[49][50][51] The formation of floating layers was carried out in quasi-stationary conditions (compression speed was 2.3 cm 2 •min -1 ). It is known that the compression speed influences on the process of formation of floating layers of organic compounds.…”

High Reactivity of Supermolecular Nanoentities of a Vitamin B12 Derivative in Langmuir–Schaefer Films Toward Gaseous Toxins

“…Nowadays, nanostructures of numerous biomolecules having different properties from those of the parent molecules and with great potential for various applications have been reported. , Self-assembly is a key player in material nanoarchitectonics, − the nanostructures formed in this way arising from molecules carrying side groups that promote the process. Supramolecular polymers have been created using diverse self-assembly strategies. , The formation of different kinds of molecular assemblies from precursor compounds at the water surface has been reported. , We previously demonstrated the possibility of supramolecular design at the air–water interface by controlling the self-assembly of tetrapyrrole compounds into 2D and 3D nanostructures. − The concept of nanostructuring of organic compounds at the air–water interface and a model of a floating layer, the structural units of which can be both individual molecules (Langmuir’s approach, special case) and their major nanostructures (so-called M-nanostructures, general case), were presented. − The formation of the porphyrin supermolecules from magnesium porphine, a functional element of chlorophyll, was reported …”
