Abstract
We report on the Langmuir-Blodgett film formation and properties of a ruthenium porphyrin complex. Multilayer films may be transferred onto a variety of substrates. Reproducible deposition is indicated by both optical and electrical measurements. Ellipsometry reveals the thicknes s per layer to be 1.65 +/- 0.05 nm. A marked increase in the in-plane electrical conductivity of these layers is found upon exposure to nitr ogen dioxide; this effect is found to be reversible at room temperatur e.
