Towards the Development of a Smart Matrix — •Regina Schmidt¹, Mathis-Andreas Muth², Peter Bauer², Martti Pärs¹, Mukundan Thelakkat², and Jürgen Köhler¹ — ¹Experimental Physics IV, University of Bayreuth, 95440 Bayreuth, Germany — ²Applied Functional Polymers, University of Bayreuth, 95440 Bayreuth, Germany

In natural chromophore systems, often the protein scaffold is exploited as a smart matrix for forming the unique electrostatic environment to promote pigment-protein functionalities. A prominent example are Chlorophylls: In antenna complexes the Chlorophylls absorb sunlight and transfer the excitation energy, whereas in the reaction centre they take part in the electron transfer chain. This is in stark contrast to manmade approaches where for each function (donor / acceptor of excitation energy, charge transfer etc.) a chemically different building block is used. In our project we want to develop an active matrix that is highly doped with photochromic molecules and into which suitable chromophores will be embedded. This will allow to convert the light-harvesting ability of the entire sample between an active and inactive state, mimicking a smart matrix that reacts on the illumination conditions.
