Abstract

Samples of 4, 4′-bis (3, 3, 3-tri-d 5-phenylpropynyl) biphenyl 2, 9, 10-bis (3, 3, 3-tri-d 5- phenylpropynyl) anthracene 3, 1, 4-bis (3, 3, 3-tri-d 5-phenylpropynyl) naphthalene 4, and 4, 4′-bis (3, 3, 3-tri-d 5-phenylpropynyl)-1, 1′-binaphthyl 5 were prepared via a Sonogashira coupling of 3, 3, 3-tri-d 5-phenylpropyne 7 and the appropriate aryl dibromide. Single crystal X-ray diffraction structures were obtained for an o-xylene clathrate of 2 and for solvent-free ...
