- A
spiropyran is a type of
organic chemical compound,
known for
photochromic properties that
provide this
molecule with the
ability of
being used in medical...
- carbon. An
example of a
spirocyclic compound is the
photochromic switch spiropyran. In fused/condensed
bicyclic compounds, two
rings share two
adjacent atoms...
- light.
Several examples of
photochromic compounds include: azobenzene,
spiropyran, merocyanine, diarylethene, spirooxazine, fulgide, hydrazone, nobormadiene...
-
thermally and
photochemically stable chromop****s (azobenzene, diarylethene,
spiropyran, etc.) are
usually used. And for the
metal complexes, a wide
variety of...
-
solutions of
photochromic spiropyran molecules to UV radiation. The
ultraviolet light induces the
conversion of the
spiropyrans to
merocyanine molecules...
- back to the 1950s, when
Yehuda Hirshberg developed the
photochromic spiropyrans and
suggested their use in data storage. In the 1970s,
Valerii Barachevskii...
- holography, as
spatial filter or
optical switching. Azobenzenes, stilbenes,
spiropyrans, are
prominent classes of
compounds subject to photoisomerism. In the...
- pillar[5]arene,
spiropyran and
pentanenitrile (free
state and
grafted to polymer) was
constructed by Wang et al.
After UV irradiation,
spiropyran would transform...
- Similarly, ring-opening and -closing
reactions such as
those seen for
spiropyran and
diarylethene can also
produce curved shapes.
Another common mode of...
- Neutrocyanines: R2N+=CH[CH=CH]n-CN and R2N+=CH[CH=CH]n-CHO
Merocyanines including spiropyrans and quinophthalones.
Apocyanines where two
quaternary nitrogens are joined...
