Abstract

Ordered ultrathin films of various dye molecules can be created by vacuum deposition onto a variety of substrates where the interaction with the overlayer is weak and intermolecular forces dominate the ordering process. Examples are shown for the surface electron diffraction data obtained from ordered monolayers of phthalocyanines on metal dichalcogenide surfaces and the corresponding linear optical changes which result from the formation of thin multilayers of those dyes. Organic/organic' multilayer assemblies are also presented, consisting of alternating layers of the fullerene C60 and InPc-Cl, which show promise for the formation of true organic superlattices, where excitonic interactions are confined in two dimensions.
