Synthesis and properties of butyl-capped dehydrothieno[14]annulenes and their conversion into terthiophenes.
A series of butyl end-capped dehydrothieno[14]annulenes (DTAs) has been prepared. These compounds were further transformed into electron-rich terthiophenes (3TPs) by reaction with sodium sulfide. The DTA and 3TP macrocycles were compared qualitatively using UV-vis spectroscopy, and the latter were found to have lower energy absorptions. The conformations of these molecules were also examined by DFT-YFLP computations.
