Molecularly defined tubular J-aggregates of amphiphilic cyanine dyes [1] and soft nanoscopic slitpores from mica and graphene [2] provide versatile platforms to understand and develop optoelectronics in both natural and artificial low dimensional systems. Upon filling the nanopores, optoelectronically active organic-inorganic hybrid systems can be obtained and investigated, such as semiconducting or metallic nanowires within a molecular nanotube or monomolecular fluids within a soft inorganic slitpore. Recent results will be discussed, including the excitonic coupling between two concentric dye nanotubes as well as energy and charge transfer in the slit nanopores filled with molecules.
