Abstract
Abstract Disclosed are a functional organic thin film formed of a monolayer or multilayers composed of reactive functional group-containing amphiphilic organic molecules in which at least one of the amphiphilic organic molecules is a precursor of a nitrene or carbene and a functional organic thin film containing at least one kind of functional organic molecules formed by the reaction between the nitrene or carbene derived from the precursor and a guest compound molecule of a different kind as well as a method of producing the functional organic thin films. Utilizing the reactivity of the thin film, a functional compound, preferably a biotechnology-related functional compound, of various kinds can be fixed onto the film for use in the sensor image formation or information recording fields.
