Porphyrin - functionalized oligo - and polythiophenes {
The synthesis and properties of a series of biand terthiophenes 3–8 substituted with meso-tetraphenylporphyrin (TPP) groups via an isolating oxaalkyl chain is described. Electrooxidative polymerization leads to the corresponding metal complexed porphyrin-functionalized polythiophenes P4–P8. The electrochemical and spectroscopic properties of the polymer films reveal the superimposition of the e...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولSynthesis, crystal structure and thermochromism of benzimidazolium
The synthesis and crystal structure of thermochromic, yellow benzimidazolium tetrachlorocuprate(II), (C7H7N2)2CuCl4 (1), have been reported. The compound crystallizes in the C2/c space group and contains discrete tetrahedral CuCl4 2 species. It absorbs one molecule of water from humid atmosphere at room temperature to produce a hydrated green form, (C7H7N2)2CuCl4 /H2O, which upon heating loses ...
متن کاملResponse of crown ether functionalized polythiophenes to alkaline ions.
The sensing response of 15-crown-5-ether functionalized polythiophene to Li+, Na+, and K+ has been investigated at the atomistic level using molecular dynamics simulations. The stability associated with all the identified binding sites has been corroborated by quantum mechanical calculations. Although the cavity of the macrocycle is not the most visited binding site, such receptor is responsibl...
متن کاملStructure and excitonic coupling in self-assembled monolayers of azobenzene-functionalized alkanethiols.
Optical properties and the geometric structure of self-assembled monolayers of azobenzene-functionalized alkanethiols have been investigated by UV/visible and near edge X-ray absorption fine structure spectroscopy in combination with density-functional theory. By attaching a trifluoro-methyl end group to the chromophore both the molecular tilt and twist angle of the azobenzene moiety are access...
