Orientation of the Absorption and Emission Transition Moments of Methine Dyes
نویسندگان
چکیده
The emission anisotropics of the fluorescence of the prolate molecules 2[4(N,N-dimethyloamino)a styrylo]benzothiazol and 2[4(N,N-dimethyloamino)a styrylojbenzoksazol in solvents of different viscosities were measured, yielding information about the rotational motion of the molecules. The non-linear dependence of 1/r on T\r\ was confirmed. On the basis of a comparison of experimental and quantum chemical calculations the orientation of the transition moments of the dye molecules is proposed.

متن کاملA new method for Eosin preparation and examination of its absorption and emission spectra
Eosin is one of the original dyes of xanthenes derivatives. It is also one of the main derivatives of fluorescein and has brilliant fluorescence. Eosin disodium salt called "Eosin Y" is the most useful form of this compound. In common procedures, eosin is usually obtained by the action of bromine on fluorescein, which has not good yield and purity degree. In this research, it is prepared by the...

Cyanine dyes are broadly used for fluorescence imaging and other photonic applications. 3,3'-Diethylthiacyanine (THIA) is a cyanine dye composed of two identical aromatic heterocyclic moieties linked with a single methine, -CH 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 0000000000000000000000000000000000 000000000000000000000000000000...
متن کاملBond alternation, polarizability, and resonance detuning in methine dyes.
We derive structure-property relationships for methine ("Brooker") dyes relating the color of the dye and its symmetric parents to its bond alternation in the ground state and also to the dipole properties associated with its low-lying charge-resonance (or charge-transfer) transition. We calibrate and test these relationships on an array of different protonation states of the green fluorescent ...
متن کاملAn Improvement in Fluorocarbon Chain Re-orientation by Reactive Dyes
There is an increasing demand for air-dry performance of fluorocarbon finished materials. Thus, dyeing with different types of reactive, mono, bi, and multi-functional, dyes was evaluated as a novel treatment to create correct surface interface to maintain fluorocarbon performance without ironing or tumble drying. The effects of pre-treatment on fluorocarbon finishing of cotton fabric, a cellul...
