The electrical properties of siloxane oligomers prepared from the reaction of 1,4‐naphthalenediol or 1,4‐naphthoquinone with diphenylsilane using different palladium catalysts, such as PdCl 2 , Pd(TMEDA)Cl 2 , Pd(TEEDA)Cl 2 (where TMEDA = N , N ′‐tetramethylethylenediamine, TEEDA = N , N ′‐tetraethylethylenediamine), are dependent on the catalyst. Thermoelectric switching properties can be obtained from the siloxane prepared from the coupling reaction of diphenylsilane with 1,4‐naphthoquinone or 1,4‐naphthalenediol using Pd(TMEDA)Cl 2 as catalyst.
