Metallosupramol. films on solid substrates have been prepd. and characterized. The films incorporated metallosupramol. polymers based on a tritopic cyclam bis-terpyridine ligand and were formed using different deposition techniques. From layer-by-layer (LBL) method, alternate thin multilayers of this metallosupramol. along with oppositely charged polyelectrolyte are constructed by electrostatic self-assembly. Using dip-coating method, homogeneous monolayers are deposited. The monolayer thickness is controlled by withdraw velocity of substrate. In a direct-assembly approach: Langmuir-Blodgett (LB), well-ordered metallosupramol. monolayer is achieved by using a Metallosupramol. Polyelectrolyte Amphiphile Complex (MPAC). The structures of these metallosupramol. thin films are characterized by X-ray reflectivity (XRR), Atomic force microscopy, Langmuir isotherms, and UV/Vis absorption. The results open access to fabricate novel mol. materials such as sensors and memory devices. [on SciFinder(R)]
