水藻素是海洋光合作用中的主要光收集色素，其向叶绿素a的能量传递效率异常高。这种能量传递效率被认为与水藻素复杂的结构有关，水藻素在多烯主链中具有烯烯和酰基丁烯内酯的功能。但是，目前还没有关于橄榄素的结构特征与其超强能量传递能力之间关系的研究。然后，我们重点研究了为什么橄榄素具有独特的烯基，以及烯基功能如何在异常高的能量转移中发挥作用。为了阐明这种烯功能的确切作用，我们现在描述了三种相对不稳定的烯修饰的橄榄素衍生物的合成，以及橄榄素的Stark光谱结果和合成的橄榄素衍生物。
Peridinin is known as the main light-harvesting pigment in photosynthesis in the sea and exhibits exceptionally high energy transfer efficiencies to chlorophyll a. This energy transfer efficiency is thought to be related to the intricate structure of peridinin, which possesses allene and ylidenbutenolide functions in the polyene backbone. There are, however, no studies on the relationship between the structural features of peridinin and its super ability for energy transfer. We then focused on the subjects of why peridinin possesses a unique allene group and how the allene function plays a role in the exceptionally high energy transfer. Toward elucidation of the exact role of the allene function, we now describe the syntheses of three relatively unstable allene-modified derivatives of peridinin along with the results of the Stark spectroscopy of peridinin and the synthesized peridinin derivatives.
