The fabrication of well-organized multilayer thin films composed of various chromophores on solid substrate has attracted significant research attention because of their potential optical, electrochemical, and catalytic properties leading to possible applications as building blocks for artificial photosynthetic solar cells, gas sensors, nonlinear optics, and molecular electronic devices.<br/>Layer by-layer (LBL) deposition technique is a powerful, low-cost, method to transfer chromophore assemblies from solution onto a solid surfaces (such as glass, quartz and various electrode substrates) while maintaining predictable nanoarchitectures and function. In this presentation, we will provide strategies developed in our group to fabricate multi-chromophore (in particular, using perylene diimides, and porphyrins) containing multilayer layer thin films on glass substrate. Importantly, our LBL fabrication technique uses sustainable aqueous media as the immersion solvent and harnesses cyclodextrin–based host-guest interactions. We will also discuss the photo-physical properties of these well-organized thin films.
