クロロフィルの化学 / Chlorophyll Chemistry

立命館大学大学院 生命科学研究科 教授 民秋 均 (たみあき ひとし)先生


Chlorophylls (Chls) are found in photosynthetic apparatuses. Chl and bacteriochlorophyll (BChl) molecules absorb sunlight and the excited energy is migrated efficiently and rapidly among these pigments in light-harvesting antenna systems. The light energy is finally transferred to (B)Chls in a reaction center, where charge separation occurs between specific (B)Chl molecules. These naturally occurring pigments have intense absorption bands in a wide range of visible regions and some of them absorb near-infrared lights intheir monomeric states as well as aggregates with J-type fashions. Their electronic absorption spectra in a solution are dependent on the peripheral substituents. Their optical properties are discussed from the viewpoint of molecular structures including composite π-skeletons.
