title: Straightforward Synthesis, Electrochemical Properties, and Gel Formation of Thiacalix[n]thiophenes.
abstract: A facile synthetic approach toward thiacalix[n]thiophene homologues (n=4-6) is presented herein. Pd-catalyzed coupling of 2,5-dibromothiophene derivatives with stannyl sulfide gave various thiacalix[n]thiophenes in good yields. The optical and electrochemical properties of the produced cavitands were investigated. Furthermore, gelation was observed in some solvents.
