| Outline of Final Research Achievements |
Multichromophore arrays of bis(2-thienyl)diketopyrrolopyrrole (DPP) and naphthalenediimide (NDI) with two ZnII-cyclens were constructed using thymidine DNAs as a scaffold via the binding of the ZnII-cyclens with thymine bases. We demonstrate photocurrent generation in a donor/acceptor heterojunction configuration consisting of the DPP (donor) and NDI (acceptor) arrays co-immobilized on an Au electrode. The co-immobilized electrode exhibited good photocurrent responses because of the efficient charge separation between the DPP and NDI arrays. In contrast, an immobilized electrode consisting of randomly assembled DPP-NDI arrays generated no photocurrent response because DPP formed ground-state charge-transfer complexes with NDI in the randomly assembled arrays. Therefore, our approach to generate donor/accepter heterojunctions based on DNA-multichromophore arrays is a useful method to efficiently generate photocurrent.
