The synthesis of perylene monoimide dye and the ability Langmuir Langmuir–Blodgett (LB) films formation are reported. perylene-like – n-butyl diester N-(n-octyl)imide perylene-3,4,9,10-tetracarboxylic acid arachidic (AA) or thermotropic liquid crystal 4-octyl-4'-cyanobiphenyl (8CB) were used to compose mixtures different mole fraction. electronic absorption emission spectra in diluted chloroform solution, a 10 μm thick sandwich cell, monomolecular film on water surface (in situ) after...
Molecular orientational order of perylene tetracarboxylic diimide, N,N'-di(n-hexyl)-1,6,7,12-tetrachloroperylene-3,4,9,10-carboxylic acid imide (Cl4-PTCDI-6C), dissolved in homologous series liquid crystals, i.e. 4-(trans-4′-n-alkylcyclohexyl)-isothiocyanato-benzene (nCHBT) and 4-n-alkyl-4′-cyanobiphenyl (nCB), is investigated by using UV–V absorption fluorescence spectroscopies. The parameter , determined experimentally for Cl4-PTCDI-6C molecules nCHBT nCB, much lower than that some other...
New dyes – aliphatic esters of 1,6,7,12‐tetrachloroperylene‐3,4,9,10‐tetracarboxylic acid were prepared as potential fluorescent light‐stable colorants for high‐visibility safety wear. The structure the 15 perylenes was confirmed by 1 H and 13 C nuclear magnetic resonance spectroscopy mass spectrometry, their spectroscopic physicochemical properties determined. An attempt made to apply synthesised products disperse in coloration polyester well polystyrene poly(methyl methacrylate). light,...
The orientational order parameters <P2> and <P4> of perylene-3,4,9,10-tetra-(n-hexylester) (PTHE) 1,6,7,12-tetrachloroperylene-3,4,9,10-tetra-(n-hexylester) (4Cl-PTHE) dye molecules dissolved in low-molar-mass liquid crystal, 4-(trans-4-n-hexylylcyclohexyl)-isothiocyanobenzene, are calculated from the experimental values polarised absorption fluorescence anisotropies. data show that substitution chlorine atoms instead hydrogen perylene core reduces value parameter. Moreover, for derivatives,...
Three dyes-diesters of monoimides perylene-3,4,9,10-tetracarboxylic acid were synthesized in three-stage process: esterification, hydrolysis, and monoimidation as potential fluorescent light-stable colorants for high visibility safety wear. The structure these compounds was confirmed by
