Diarylethene magnetic interactions

Diarylethene as a Photoswitching Unit of Intramolecular Magnetic Interaction... [Pg.329]

Table 9.1 Magnetic interaction between two nitronyl nitroxide connected by diarylethene photoswitches.

Attempts to photoswitch the intramolecular magnetic interaction based on photo-chromism of diarylethenes have been overviewed. The switching between the disjoint and non-disjoint structures caused a change in the interaction between the separated spins. Photochromic diarylethene is one of the most favorable photoswitching units for magnetic interactions. This system has the possibility to be applied to the molecular-scale information processing system [73-77]. [Pg.348]

Photochromism is the reversible, light-driven conversion of a molecule between two forms with differing absorption properties. Molecular examples are numerous and include fulgides, dihydropyridazines, spiropyrans, spirooxazines and diarylethenes. The reorganisation of the electrons involved in the transformation means that photochromism is often accompanied by the modulation of other attributes such as fluorescence intensity, redox properties, magnetic interactions and non-linear optical...
