Self-assembly of supramolecular architectures in solution and on surfaces

Supramolecular chemistry gives powerful tools to scientists for fabrication of new functional materials. Constant studies over nature of multiple interactions in biological systems, their application in chemistry and material science, finally fabrication of new devices available for wide community, allow progress and help humanity in everyday life. The present thesis is focused on design of applied supramolecular architectures for fascinating applications in material science, synthesis of building blocks for these systems and final assembly of subunits into functional materials, when possible. Main part of thesis harvest exceptional complexation properties of tetraphosphonate cavitands towards charged organic ammonium salts. They have been employed for building hierarchical luminescent complexes on silicon (Chapter 3), synthesis of luminescent dyes aligning in liquid crystal displays (Chapter 4), sensing of charged amines in water environment (Chapter 7), and their model compound, metal bridged cavitands, have been synthesized as building blocks for metal organic frameworks (Chapter 2). Second part of thesis is focused on chemistry of phthalocyanines, synthetic macromolecules with particular optical and electronic properties, which upon proper functionalization and organization on the surfaces can find applications in organic photovoltaics as very strong light absorbents and electron donors/acceptors (Chapter 5). Sandwich complexes with terbium opened area of new applications in spintronics due to its single molecule magnet properties (Chapter 6), where rational organization on surfaces is crucial.
