New Fluorescent Amide-Functionalized Phenylethynylthiophene Low Molecular Weight Gelator
摘要:
An amide-functionalized phenylethynylthiophene gelator has been synthesized. Self-assembly of this molecule via cooperative hydrogen bonding and pi-stacking induced gelation of a variety of organic solvents. The presence of aggregates was confirmed by concentration-dependent absorption and fluorescence properties. SEM and TEM studies reveal the formation of fiberlike nanostructure.

sequential cross-couplingreactions of sterically hindered tetrabromothiophene with arylboronic acid and an alkyne/alkene to afford selective bi-, tri-, and tetrasubstituted aryl/alkynyl-thiophenes with the aid of a palladium catalyst were described. The reaction proceeds via a site-selective Suzuki/Sonogashira coupling, followed by selective Sonogashira, Suzuki and Heck coupling reactions. This methodology
