Outline of Final Research Achievements |
Recently, a variety of synthetic methods have been developed to synthesize three-dimensional (3D) conjugated molecompounds. In this research, we prepared a series of thiacalix[n]dthiophenes (n =4 - 6) and thiacalix[n]dithiothiophenes (n = 4 - 10) by a facile palladium-catalyzed coupling reaction of thiophene/dithienothiophene derivatives with bis(tributyltin)sulfide. In cyclic voltammetric measurements, all compounds exhibit reversible multielectron redox processes owing to electronic delocalization over whole molecules. The thiacalix[n]dithiothiophene derivatives associated with fullerene molecule in the cavity. The X-ray analysis or electronic spectra suggest stable 1:2 complexes (n =4) or 1:1 (n=5, 6) complexes.
