A p-tertbutylcalix[4]arene derivative was synthesized from a reaction of the diisothiocyanate p-tertbutylcalix[4]arene, obtaining crystals that were then characterized by mass spectroscopy, Raman spectroscopy, and single-crystal X-ray diffraction. The molecule presents two acid carbamothioic-n-ethoxy-methyl-ester substituent groups. Through crystallization of this compound, it was also found th...

The metal complexes of Azo dye; 4,4'-((methylene bis(3,l-phenylen)) bis (diazene-l,2-diyl)) bis(1,3-Benzenediol) are produced from 4,4`- methylenedianiline and Resorcinol were synthesized characterized by using several analytical spectral techniques. ligand its many chemo-physic methods like NMR, IR, UV-Vis, molar conductance measurement, melting point. conditions optimal reaction (for instance...

We investigate the kinetics of DNA hybridization reactions on glass substrates, where one 22 mer strand (bound-DNA) is immobilized via phenylene-diisothiocyanate linker molecule on the substrate, the dye-labeled (Cy3) complementary strand (free-DNA) is in solution in a reaction chamber. We use total internal reflection fluorescence for surface detection of hybridization. As a new feature we per...
