Surface Modification and Controlled Assembly of Molecular Materials

Single crystal molecular organization was investigated using coordination network crystals. Crystals that had molecules arranged as chains, such as catena-poly[dicyanobenzene-silver(I)]-triflate, were exposed to inhibitors specifically designed to bind at the growing surface. It was found that inhibitors had qualitative effects on the morphology and on the surface composition of the crystals and that the surface and bulk properties had potential to be modified independently. Copper-pyridine crystals were studied to determine how the steric bulk on pyridine influenced the pyridine coordination to copper. It was found that as the steric bulk of the pyridine increased, the probability that all the copper coordination sites were occupied with pyridine decreased, and that solvent molecules and ancillary ligands also coordinated to copper. A single crystal of 4'-undecyloxy-4-biphenyl carbonitrile revealed that the molecules in the crystalline form had similar organization as the molecules in the smectic phase.
