Research on hybrid inorganic‐organic materials has experienced an explosive growth since
the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild …

Naphthopyran molecular switches undergo a ring-opening reaction upon external
stimulation to generate intensely colored merocyanine dyes. Their unique modularity and …

Materials exhibiting reversible changes in optical properties upon light irradiation have
shown great potential in diverse optoelectronic areas. In particular, the modulation of …

Transparent photochromic (PC) films can be used for smart window applications to partially
block the sunlight and provide comfort vision. However, for large area applications, the high …

Benzo-annulated chromenes, ie, naphthopyrans, are well-known photochromic molecules
that undergo photochemical ring-opening reactions to form two colored open-ring isomers …

Photofunctional compounds have emerged as critically important materials for both
fundamental studies and industrial applications. Control of the thermal decoloration speed to …

Exfoliation of layered porous metal-organic frameworks (MOFs) in a top-down fashion
constitutes a successful approach to 2D metal-organic nanosheets (MONs), the analogs of …

This paper reports on durable and nearly temperature-independent (at 298–328 K) T-type
photochromism of colloidal Cu-doped ZnS nanocrystals (NCs). The color of Cu-doped ZnS …

Diarylbenzo-and naphthopyrans are one of the important and well-known classses of
organic photochromic systems. Their photolysis leads to highly colored o-quinonoid …

Photochromic silica nanoparticles (SiO2@ NPT), fabricated through the covalent
immobilization of silylated naphthopyrans (NPTs) based on 2 H-naphtho [1, 2-b] pyran (S1 …
