Light on molecular machines, devices, and materials

The application of a bottom-up approach to the design, preparation andcharacterization of chemical systems that span from molecular scale devices and machines to bulk materials is a stimulating challenge of nanoscience. The interest on this kind of systems arises from their ability to perform a (useful) function in response to chemical and/or physical stimulation. In this context, the use of light stimulation has several advantages, primarily because photons can be used to supply energy to the system (i.e., write) as well as to gain information about its state (i.e., read).In this seminar I will describe investigations undertaken in our laboratories, aimed at photo-inducing and -controlling large-amplitude molecular motions, both under thermodynamic and kinetic viewpoints, in multicomponent (supramolecular) species that comprise photoreactive elements. Progress towards the construction of light driven molecular pumps working in solution and photoswitchable solid materials for optoelectronic and gas storage applications will be presented. I will also discuss recent results related to the construction of nanoconjugates composed of semiconductor quantum dots coated with functional organic ligands, designed to exhibit sensing andswitching functionalities.
