Possible applications of thiophenes in radiopharmaceutical chemistry have been explored. Thiophene for benzene ring substitution was applied to the synthesis of thienyl-[18F]GBR 13119, an analog of the potent and selective dopamine uptake inhibitor [18F]GBR 13119. In vivo regional brain distribution

Three new tetradentate NNNS Schiff bases (L1-L3) derived from 2-(piperidin-4-yl)ethanamine were prepared in high yields. UV-Visible and FTIR spectroscopy were used to monitor the dehydration reaction between 2-(piperidin-4-yl)ethanamine and the corresponding aldehydes. Structures of the derived Schiff bases were deduced

The molecular packing structures of two conjugated polymers based on alkoxy naphthalene, one with cyano-substituents and one without, have been investigated to determine the effects of electron-withdrawing cyano-groups on the performance of bulk-heterojunction solar cells. The substituted cyano-groups facilitate the
