  Pleiadene Dimerization and Its Application to the Construction of Novel Carbon Networks

  摘要：

  The synthesis of the anti- and syn-pleiadene dimers 2 has been carried out in solution and in the solid state from (6b-10b-dihydrobenzo[j]cyclobut[a]acenaphthylene) (3). The structures of the anti- and syn-2 dimers were determined by X-ray crystallography and by NMR spectroscopy and mass spectrometry. An exhaustive thermal analysis of the two dimers has been carried out, establishing that the equilibrium for their interconversion occurs via pleiadene as an intermediate species. Vinyl-6b-10b-dihydrobenzo[j]cyclobut[a]acenaphthylene (5) has been synthesized and used as a pre-monomer for the preparation of poly(pleiadene) dimer through either thermal or photochemical polymerization.

  In this paper the synthesis and characterization of a new class of molecules based an 6b,10b-dihydroobenzo[j]cyclobut[a]acenaphthylene (DBCA) with potentially interesting optical and electronic properties are described. The mentioned compounds contain one or two DBCA units linked via a double bond to an aromatic system. The synthesis of these compounds is mainly carried out by Heck and/or Wittig reactions. The introduction of DBCA units in molecules is interesting in two respects: (1) It will influence the electronic and optical properties of the compounds, and (2) it will induce dimerization (polymerization) because DBCA can, upon thermolysis or photolysis, be converted into a biradicaloid species ("pleiadene") which dimerizes. Thus suitable compounds could be used as monomers for photochemically or thermally induced polymerization.

  Four new zinc phthalocyanines (ZnPcs 1–4) peripherally substituted with fully conjugated 6b,10b-dihydrobenzo[j]cyclobut[a]acenaphthylene (DBCA) have been synthesized and chemically characterized. In ( DBCA )₄ ZnPc 1 and ^t Bu ₃( DBCA ) ZnPc 2 the DBCA units are directly connected to the phthalocyanine core, meanwhile in ( VDBCA )₄ ZnPc 3 and ^t Bu ₃( VDBCA ) ZnPc 4 DCBA units are connected through a vinyl spacer. We describe the effect of the substituents on optical spectra, fluorescence lifetimes and quantum yields.
