A pair of enantiomerically pure metallodimers containing two deeply concave tribenzotriquinacene (TBTQ) units linked by a platinum-diacetylene unit were synthesized. Such linear metal-centered TBTQ dimers are considered as edges of metallosquares and metallocubes that bear four or eight mutually syn-oriented TBTQ bowls at their tips, respectively. The structures of the metallodimers were characterized by 1H, 13C and 31P NMR spectroscopy, ESI mass spectrometry, and circular dichroism. The single X-ray crystal structure of (+)-enantiomer confirmed the absolute configuration of the metallodimers and revealed an edge (tip-to-tip) length of 18.456 Å and an approximated syn-orientation of the two TBTQ bowls in the solid state.

AbstractThe synthesis and characterization of an optically active quinquethiophene monomer 3,3””-didodecyl-4’,3”’-di[(S)-(+)-2-methylbutyl]- 2,2’:5’,2”:5”,2”’:5”’,2””-quinquethiophene [(S)-(+)-DDDMBQT], bearing at the C-β positions of thiophene rings both linear C12 alkyl chain and chiral, enantiomerically pure, alkyl group is described. The polymerization of [(S)-(+)-DDDMBQT] by oxidative mechanism has been optimized in terms of yield of soluble polymer with high molecular weight.The obtained polymeric derivative displays enhanced conjugation extension with respect to similar poly(3-alkylthiophene)s reported in the literature and optical activity in the spectral region related to the chromophore absorptions when in the microaggregate state, indicative of the presence of supramolecular chiral conformations.
