  A Non-Covalent Strategy for the Assembly of Supramolecular Photocurrent-Generating Systems

  摘要：

  Three photocurrent-generating thin films were assembled on gold surfaces. SAM I was constructed from molecules consisting of an alkyl disulfide group linked covalently to a 12-residue helical peptide and terminated with an alanine residue containing a pyrene chromophore. SAM I served as a benchmark for multilayered films II and III in photocurrent generation experiments. Films II and III were assembled from several components that were linked noncovalently by metal-ligand complexation. Cyclic voltammetry and contact angle measurements suggest that the films consist of ordered layers with relatively few defects. Photoexcitation of SAM I by the output of a 350 nm lamp ( approximately 0.2 mW power incident on the sample) results in current generation in the range 5-10 nA/cm2. Photoexcitation of II and III yields higher current in the range 10-30 nA/cm2, representing a quantum efficiency of approximately 1%. The observation of comparable or higher current from noncovalently assembled multicomponent films indicates that this method of assembly may obviate the problems associated with the covalent assembly of devices from large molecules.

  Self-assembled monolayers and multilayer thin film structures were assembled from multiple components that were linked non-covalently by metal-ligand complexation. Non-covalently assembled multicomponent films assembly my the present method obviate problems associated with the covalent assembly of SAMs and multilayer thin film structures from large molecules. In one preferred embodiment, the disclosed film structures comprise 2,6 pyridinedicarboxylate ligands attached to an alkanethiol, which form a self-assembled monolayer on gold. The SAM is subsequently functionalized by sequential deposition of metal ions and ligands, allowing incorporation of one or more chromophores, photooxiding compounds or photoreducing to form multilayer film structures. Transition metals, lanthanide metals and other metals of varying charge may be employed in complexing with with 2,6 pyridinedicarboxylate ligands to form stable ordered structures. The non-covalent assembly method provides for multilayer film formation from mixtures of metal ions and a varying number of film layers. Multilayer thin film structures exhibit stable cathodic photocurrent generation in the presence of methyl viologen or EDTA in solution.

  自组装单分子层和多层薄膜结构是由多个组分非共价地通过金属配体络合连接而组装而成的。通过本方法非共价组装的多组分薄膜组装消除了由大分子的共价组装形成的SAMs和多层薄膜结构所带来的问题。在一个优选实施例中，所公开的薄膜结构包括连接到烷硫醇的2,6-吡啶二甲酸配体，其在金上形成自组装单分子层。随后，通过金属离子和配体的顺序沉积来功能化SAM，从而允许将一个或多个发色团、光氧化化合物或光还原化合物并入其中，形成多层膜结构。过渡金属、镧系金属和其他带电金属可以用于与2,6-吡啶二甲酸配体形成稳定有序结构的络合。非共价组装方法提供了从金属离子和不同数量的薄膜层混合物中形成多层薄膜的方法。多层薄膜结构在存在甲基紫或EDTA的溶液中表现出稳定的阴极光电流产生。
