A sustainable energy future is likely to require the widespread use of renewable energy technologies. Artificial organic and inorganic light-harvesting assemblies are being intensively explored as possible components of solar cells. Combining both inorganic and organic light harvesting materials aims to create an optimal light harvesting system. The linker is a vital component of any supramolecular light-harvesting assemblies and influences its photophysical properties. We investigated the non-covalent interactions of organic soluble quantum dots (QDs) with different non-charged prophyrin chromophores. We varied the chemical type of the linkers on chromophore, the number and orientation of linkers on chromophore. We will present light absorption and energy transfer properties of differently substituted porphyrin-QD systems. We will also report the binding affinity between porphyrins and QDs as well as stability of porphyrin-QD complexes.
