During the past few decades, interest has been rapidly growing in gaining insight into the
properties and transformations of the so-called bistable compounds and molecular systems …

Photochromism is defined as a reversible transformation in a chemical species between two
forms, and in these reversible processes, at least one pathway is induced by …

Time temperature indicators (TTIs) are devices used for recording thermal history and
indicating the remaining shelf life of perishable products throughout their storage …

The second edition of this best-selling handbook is bigger, more comprehensive, and now
completely current. In addition to thorough updates to the discussions featured in the first …

Spiropyran dyes were attached to fluorescent core− shell CdSe/ZnS nanocrystals via thiol-
containing linkers. Photoisomerization of the dye to its merocyanine form by UV irradiation …

A photochromic nitrospiropyran moiety (Sp) has been covalently linked to a zinc (PZn) and
to a free-base (PH2) porphyrin. In the resulting dyads (PZn− Spc and PH2− Spc), the …

The review surveys synthetic approaches to spiro [1, 4] oxazines belonging to one of the
most promising classes of organic photochromes. The relationships between the structures …

In the present paper, a new spirobenzopyran derivative was synthesized and applied in
simultaneously colorimetric and fluorescence ratiometric detections of Cu2+. In contrast to …

Studies on the following were reviewed:(1) the structure of spiropyrans and spirooxazines
(two kinds of spiro compounds) under external stimuli and (2) the construction and …

Photochromic dyes possess unique properties that can be exploited in different domains,
including optics, biomedicine and optoelectronics. Herein, we explore the potential of …
