Cover: Langmuir-Blodgett films of the cellulose derivativecontaining porphyrins, porphyrin-cellulose, were fabri-cated to construct the cellulose-based molecular photo-current generation system. On visible light illumination ofthe LB monolayer film deposited on an ITO electrode,anodic photocurrents were observed. This is becauseporphyrins are located at a distance of approximately1.03 nm along the cellulose backbone. Further details canbe found in the article by K. Sakakibara,* Y. Ogawa,H. Kamitakahara, T. Takano, and F. Nakatsubo onpage 1270.
