Abstract
Electrodes with a gap size of 15 ∼ 80 nm could be bridged by porphyrin molecular wires with 50 ∼ 300 nm length. The porphyrin units could be coordinated with Au nano-particles having pyridinyl moiety. The device with both the porphyrin and Au nano-particles showed photo-response characteristics while those without the Au nano-particles showed no response.
