Metal containing polyynes

Alkynyl ligand transfer from Cu to group 10 metals is applied to synthesis of metal containing polyyne polymers. An equimolar reaction of bis(ethynyl)pal-ladium complex and dihalogenopalladium complex in the presence of base and Cul causes condensation to give the polymer having ethyndiyl and Pd in an... 

The metal-containing polyynes are an interesting class of main-chain organometallic polymers that have been under investigation since the 1970s. These systems are known for their rigid-rod stractures and electronic communication over the extensively... 

Metal containing polyynes are multifunctional materials which combine the properties of organic polymers with those of metal centers coordinated to the organic moiety and are able to form nanotemplates, colloidal photonic crystals, multilayer capsules and hollow vesicles [127, 128], An example of a rod-like polymetallayne self-assembly in hollow nanorods has been recently reported [129] the computer simulations of the nanostructure show that the polymer chains are ordered in parallel lines that give rise to a tubular morphology rather unusual for these materials, but promising for sensor devices applications.
