Procedure

4 Ethynylpyridine and 1,4-bis-4-pyridylbutadiyne were synthesized by previously reported methods. L. D. Ciana et. al., J. Heterocyclic Chem., 21:607 (1984). 1,2-bis-4,4'-dipyridylacetylene was prepared by the method outlined by Ludi et al. M. Tanner et al., Chimia, 34:23 (1980). 2-Ethynylpyridine was obtained from Farchan Laboratories. Acetonitrile (HPLC grade) was obtained from VWR Scientific and was distilled under nitrogen before use. 1-Bromododecane and ethyl iodide were obtained from Aldrich Chemical Company.
