Zinc is an important biogenic element which is able to connect with indicators such as a spiropyran. The spiropyran is known for its fluorescent character and selectivity towards zinc ions (and some other metal ions, e.g. cadmium). ...

Kinetics of photochromic reaction of spiropyrane dissolved in a poly(phenylenevinylene) derivative MEH-PPV was studied by optical and impedance spectroscopy. Spiropyrane forms metastable, highly polar merocyanine under illumination ...

We present a new type of light responsive self-assembling structures based on a spiropyran photoswitchable unit. The spiropyran central part was modified by functional groups, which enabled the connection of two structurally differe...

Photochromic transformation of spiropyran dye leads to the formation of energetic level inside the energy gap of the surrounding matrix and therefore to the creation of switchable charge trap. Properties of such systems were investigated by ...
