Peridinin, a nor-carotenoid, exhibits an exceptionally high energy transfer efficiency to chlorophyll a in photosynthesis in the sea. This efficiency would be related to the unique structure of peridinin. To answer the question of why peridinin possesses the irregular C37 skeleton, we have achieved the synthesis of three peridinin derivatives. Their ultrafast time-resolved optical absorption and Stark spectra measurements have shown the presence of the characteristic intramolecular charge transfer state and the featured electrostatic properties of peridinin.
多甲藻素是一种去甲类胡萝卜素，在海洋光合作用中，它对叶绿素a的能量转移效率极高。这种效率可能与多甲藻素独特的结构有关。为了回答多甲藻素为何具有不规则C37骨架这一问题，我们合成了三种多甲藻素衍生物。它们的超快时间分辨光吸收和斯塔克光谱测量结果表明，存在特征性的分子内电荷转移态以及多甲藻素特有的静电性质。
