摘要:Abstract(#br)A group of dicyanodihydrofuran (DCDHF) fluorophores with thiol-reactive maleimide functionality has been synthesized. One of the methods involves aromatic nucleophilic substitution reaction between an arylfluoride containing DCDHF and an amine containing protect...

摘要:Abstract(#br)We have found that N , N -dimethylethanolamine (deanol) is a useful solvent and ligand for copper catalyzed amination of a variety of unactivated and activated 2- or 3-halothiophenes. Primary amines, acyclic secondary amines, cyclic secondary amines and acyclic secon...

摘要:Abstract(#br)A copper-catalyzed amination of aromatic halides under mild conditions using N , N -dimethylaminoethanol as solvent is described. We have studied this reaction in some detail varying the copper source, base, water content and other parameters including the scope of u...

摘要:Abstract(#br)Copper-catalyzed amination of aryl bromides and iodides under mild conditions has been developed with 2-dimethylaminoethanol as ligand and water as solvent. A variety of hydrophilic and hydrophobic aryl halide substrates have been aminated in good yield with a variet...

摘要:Abstract(#br)We have synthesized several series of DCDHF fluorophores with the amine donor either acyclic or constrained in one or two tetrahydroquinoline rings. The absorption and the fluorescence emission wavelengths and quantum yields have been determined and correlated w...

摘要:Abstract(#br)The dynamics of excitation energy transport in a benzene centered branched molecule are presented. This system contains pyridine distrylbenzene (pyridine-DSB) chromophores attached to the benzene center giving the 1,3,5-tris((E)-2-{4-[(E)-2-pyridin-4-ylvinyl]phe...

摘要:Abstract(#br)A series of dicyanomethylenedihydrofuran (DCDHF) fluorophores with different hydrophilic groups were synthesized and their photophysical properties and water solubilities were measured. Significant water solubility was achieved without compromising desirable photophy...
