Transition metal complexes of axially chiral tetrathioether bay-substituted perylene bisimide dyes.

Nucleophilic substitution of 1,6,7,12-tetrachloro perylene bisimide (PBI) with n-butanethiol provided a novel, highly twisted PBI bearing four sulphur coordination sites at the bay positions, from which silver and palladium complexes were prepared. [ABSTRACT FROM AUTHOR]
