                                Synthesis and characterization of the title compound (1) is described.  UV and variable temperature H-1-NMR spectroscopy are used to deduce structural detail of 1 in solution and results are compared to its x-ray structure.  1 shows structural features favorable for cyclopolymerization to form polymers containing stacked aromatic rings.
