Some Heterocyclic Precursors as Main Entity for their Functional Dyes

"Synthesis of Some New Selected Heterocyclic Precursors and their Functional Dyes" Chemical Researcher (Water & Sanitation Company in Aswan). Chemistry Department, Aswan-faculty of Science, Aswan, Egypt.The motivation of the synthetic process of new N-bridge head Heterocyclic functional & related cyanine dyes especially of self assembly ICT] endocyclic moieties is to improve the specific characterization, photosensitization behaviour & probable application in the field of biology, medical Science, technology and physics. N-Bridge head heterocyclic functional & related dyes were identified by elemental & spectral analyses. The absorption spectra properties of some selected dyes were investigated in 95% Ethanol to attempt & throw some light on the influence of such new heterocyclic nuclei and to compare or evaluate spectral behaviors.
