Synthesis and photophysical properties of [60]fullerene-oligo(thienylene–ethynylene) dyads
摘要:
Two series of [60]fullerene-linked oligo(2,3-thienylene-ethynylene)s and oligo(2,5-thienylene-ethynylene)s have been synthesized to elucidate their photophysical characteristics. Their fluorescence spectra in toluene reveals distinct photoinduced intramolecular interactions between the oligomers and C-60, which occur in a through-space fashion for the 2,3-thienylene-ethynylene system and in a through-bond fashion for the 2,5-thienylene-ethynylene system.

A programmed synthesis of privileged arylthiazoles via sequential C–Hcouplings catalyzed by palladium or nickel catalysts has been accomplished. This versatile protocol can supply all possible arylthiazole substitution patterns (2-aryl, 4-aryl, 5-aryl, 2,4-diaryl, 2,5-diaryl, 4,5-diaryl, and 2,4,5-triaryl) from an unfunctionalized thiazole platform by 11 distinct synthetic routes. We have generated

at norepinephrine transporters (NET), we have introduced both five- and six-membered heteroaromatic moieties such as substituted pyridyl, pyrazinyl, pyrimidyl, thiazolyl, and mono- or disubstituted thienyl groups into conformationally constrained, tricyclic tropane analogues. A number of (Z)-9-(heteroarylmethylene)-7-azatricyclo[4.3.1.0(3,7)]decanes were synthesized, and their abilities to block dopamine
