Luttinger catalyst system

One of the most interesting alternatives to the Shirakawa catalyst has been the systems disclosed by Luttinger 22-23) and later elaborated by Lieser et al. 24). The tris(2-cyanoethyl)phosphine complex of nickel chloride reacts with sodium boro-hydride to produce a catalyst system capable of polymerizing acetylene in solutions in either alcohol or, quite remarkably, water. A more efficient catalyst is obtained by replacing the nickel complex with cobalt nitrate. Interest in Luttinger polyacetylene seems to have waned in the last few years. 

The data compiled in Table 4 clearly show that the surface of the sample accessible to the chemical reaction in the "doping" is one of the most important parameters. They also show that the catalyst system used (Shirakawa vs. Luttinger) and the method of preparation of the free standing film (in situ preparation vs. successive polymerization and film formation) is of little consequence as far as the level of conductivity is concerned.
