 Title    Biomimetische Photosysteme zur sakrifiziellen Wasserreduktion Novel Biomimetic Systems for Visible Light Induced W ater Reduction  
 Abstract    Sacrificial W ater Reduction, Physical Model System for Photosynthesis, Biomimetic Systems Novel microheterogeneous systems for the direct photoreduction of water using visible light in analogy to the photochemical reaction center of Rhodopseudom onas viridis are described in detail. These physical model systems for photosynthesis feature the recently synthesized bis-heteroleptic metal complexes [Ru(bpy)2(PP)]Cl2, [Ru(bpy)2(PPB)]Cl2, [Ru(bpy)2(PPB-pCl)]Cl2 and [Ru(bpy)3]Cl2, adsorbed on a negatively charged S i0 2-T i 0 2-cofloid, the zwitterionic elec­ tron relay PVS and a long-term stable and highly efficient T i0 2-P t -"antenna" catalyst as well as TEOA as sacrificial electron donor. Evidence for the directed absorption o f the sensitizers on the S i0 2-T i 0 2-colloid is taken from UV-VIS-measurements, steady-state luminescence-spectroscopy and the quantum yields for PVS-reduction. The hydrogen production in the presence of the S i0 2-T i 0 2-colloid is clearly enhanced and proofs the validity of the underlying concept of physical model systems for photosynthesis.

 Title    Synthese von seitenkettenmodifizierten Analogen des Allergens Primin Synthesis of Side-Chain-Modified Analogues of the Allergen Primin  
 Abstract    Benzoquinones such as primin (2-methoxy-6-pentyl-l ,4-benzoquinone) from Primula ob-conica H A N C E (Primulaceae) are known to be strong sensitizers and thus the source of severe allergic contact derm atitis (cell-mediated type of allergy). In order to determine the relation­ ship between sensitizing capacity and chemical structure the synthesis of 19 side-chain-modi-fied analogues of primin was carried out. With each of these primin derivatives 10 guinea pigs were sensitized using a modified FCA-m ethod (FCA = Freund's complete adjuvant). Elicita­ tion was done open epicutaneously with 0.001 molar concentrations. In these sensitization ex­ periments 2-methoxy-6-alkyl-l ,4-benzoquinones (chain length C , -C 15) showed ascending sen­ sitizing potency with increasing number of the side chain carbon atom s reaching maximum activity at an alkyl chain of 10 to 11 carbons. Beyond this point a decrease o f the sensitizing potency in correlation with a further prolongation of the side chain was observed.
