  Synthesis and Photophysical Properties of Biphenyl and Terphenyl Arylene–Ethynylene Macrocycles

  摘要：

  A series of single-walled carbon nanotube precursors, C-3h-symmetric cyclotri(ethynylene)(bipheny1-2,4'-diyl) and cyclotri(ethynylene)(p-terphenyl-2,4 ''-diyl), have been prepared by a linear stepwise oligomerization-cyclization route and by statistical intermolecular cyclooligomerization. In addition to producing these members of a novel class of arylene ethynylene macrocycles, 1 and 2, the latter statistical process produces the smaller cyclic dimer, cyclodi(ethynylene)(p-terphenyl-2,4 ''-diyl) and the larger cyclic tetramer cyclotetra(ethynylene)(bipheny1-2,4'-diyl). These macrocycles display large Stokes shifts in their fluorescence spectra. Their biphenyl or terphenyl connectivity prevents these macrocycles from achieving full planarity in the ground state, and the ethynylene moieties could provide synthetic access to cyclic arylene oligomers and discrete carbon nanotube segments.
