Currently a new trend is formed in nanotechnology “bottom-up”: molecular engineering of molecular devices and machines for various purposes. We propose a new unique class of polyfunctional light-sensitive compounds: unsaturated dyes functioning as photochromes, fluorophores and ionophores. A large body of research has been performed for their synthesis, determination of their spatial structures, study of self-assembly features to give nanosized systems, and also study of fluorescent, photochemical and complexing properties [1-3]. Resulting from the research, we elaborated for the first time universal molecular meccano, allowing one to accomplish building-up, with using a limited number of complementary compounds, light-sensitive and light-emissive nanosized systems of varied architecture with adjusted properties. Within the same class of compounds one can construct in solution, solid and at the air-water interface new types of photoswitchable molecular devices, photocontrolled molecular machines, photosensitive monolayers and monocrystals susceptible to all of the key photoprocesses [4]. The high practical value of these studies deserves attention. They provide a new strategy for the design of materials for nanophotonics, which was demonstrated, first of all, by the creation of practically important sensor and photochromic materials.
