発明の名称 (英語) Application of lignin derivatives to photoelectric transducer and photoelectrochemical cell
発明の概要(英語) The invention regards application of lignin derivatives to a photoelectric transducer. The photoelectric transducer of the invention includes a semiconductor film as a thin film electrode, that is photosensitized by one or multiple lignin derivatives selected from the group consisting of: (a) a lignophenol derivative or a phenol derivative of lignin that is prepared by solvating a lignin-containing material with a phenol compound and adding an acid to the solvate; (b) a secondary derivative that is prepared by one reaction of the lignophenol derivative (a) selected among acylation, carboxylation, amidation, introduction of a crosslinking group, and alkali treatment; (c) a higher-order derivative that is prepared by at least two reactions of the lignophenol derivative (a) selected among acylation, carboxylation, amidation, introduction of the crosslinking group, and alkali treatment; (d) a crosslinked secondary derivative that is prepared by crosslinking the secondary derivative (b) obtained by the introduction of the crosslinking group; and (e) a crosslinked higher-order derivative that is prepared by crosslinking the higher-order derivative (c) obtained by the introduction of the crosslinking group.
