Organic-inorganic hybrid perovskites allow for creating a wide variation of structures: from a 3D structure using small organic building blocks to essentially 2D layered structures using larger organic building blocks. This opens an avenue towards a quite new class of organic-inorganic nano-composites in which the inorganic perovskite sheet acts as a template for the self-assembly of organic chromophores confined between the sheets of the inorganic layer. Consequently an organization can be obtained for the organic chromophores that resemble the order observed in a single crystal. The number of inorganic sheets can easily be tuned by changing the stoichiometry of the organic small and large building blocks. In this way, a fluent transition of electro-optical properties can be achieved of the inorganic part from confined 2D structures to strongly delocalized quasi-3D structures.
