Platinum(II) extended linear chain (ELC) materials are stacks of square planar platinum complexes held together by a linear chain of platinum-platinum bonds. Two isomers exist, the "neutral" ELC with two isonitriles and two cyanides coordinated to each platinum, and the "double salt" ELC with alternating platinum tetrakisisonitrile dications and platinum tetrakiscyanide dianions. The double salts are of interest to us due to their vapochromic properties and possible application as sensor transducers. This research focuses on whether it is possible to synthesize chiral platinum(II) ELCs that can distinguish between enantiomers of chiral vapors. The synthesis and characterization of six new chiral isonitriles and their double salts will be presented.
