Studies on the organometallic palladium coordinated carbosillane liquid crystalline dendrimer

A novel complex - palladium-coordinated ate-type liquid crystalline dendrimer was synthesized by a divergent approach, The product showed liquid crystalline properties from 115 degrees C to 187 degrees C, and it belonged to dinuclear species, containing two palladium centers linked by two bridging Cl, each palladium atom completes its coordinations with N atom and a sigma bond to an ortho-carbon in the phenyl ring. The microanalytical values obtained for the product are in agreement with those of compound containing ligand, palladium:and chlorine in a molar ratio of 1 : 1 : 1 and 12 palladium atoms for every scaffold.
