Abstract

The synthesis of some cyclophanes bearing in the linear side-chain carbon-carbon triple bonds conjugated with thiophene rings has been reported. Structure analysis of the products based on extensive NMR investigation is presented. UV-Vis absorption spectra and fluorescence spectra have been measured. The analysis of the spectra points out a correlation between the maxima and the structure of the side-chain. The replacement of a benzene ring with a thiophene ring causes a bathochromic shift when the benzene ring close to the paracyclophane moiety is replaced
