WebA novel thermally stable fluorescent molecular switch with [2 + 2] photocycloaddication and cycloreversion and its application in 2D and 3D optical data storage were demonstrated. The reversibility of the photochemical reaction in the solid state was effectively improved by introducing a dipole into the molecular system. WebThe photocycloreversion reaction of a diarylethene polymer in the vicinity of silver nanoparticles was enhanced by 2–6 times relative to the reaction without the nanoparticles. The promotion of the photocycloreversion reaction is due to enhancement of the electromagnetic field near the surface of the silver core.

The former yields in the crystalline phase were twice as large as those in solution. This can be attributed to only photoreactive antiparallel conformers being packed in the crystals, while in solution both …
