Photochemistry of hypocrellin derivatives under anaerobic conditions被引量:2
《Chinese Science Bulletin》2000年第7期597-603,共7页Yuying He An Jingyi Lijin Jiang 
To improve the red absorption and solubility of hypocrellin, we have synthesized a series of hypocrellin B derivatives. The pnotochemistry of these new compounds in anaerobic media has been investigated by using elect...
