摘要：

Affairs of state: Investigation of the photochromic properties of a combined naphthopyran and diarylethene biphotochromic system (1) has revealed that four different states with entirely different absorption behaviors are formed. Opening of the naphthopyran ring leads to conjugation and electronic connection of both photochromes, while closure of the open diarylethene system extends the π-electron system over the whole molecule.
