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 naphthopyr

(Chemical Equation Presented) The photochromic performance of a hybrid system connecting naphthopyran and dithienylethene was investigated, and the photochemistry of eight different isomers was explored by choosing an appropriate wavelength of light.

Detailed 1H NMR kinetic investigations of the photochemical and thermal behaviour of a recently described poly-photochromic molecule including both dithienylethene and naphthopyran groups are reported. The combination of two photochromic moieties allows the selective controlled extension of the conjugated pi-electron system and the modulation of the absorption behaviour between ～380 to ～750nm. It is shown that the two photochromic entities are coupled and do not behave independently. Copyright
