The phenomenon of metachromasia, which is related to molecular aggregation, leads to
significant changes in the photophysical properties of dyes. This review summarizes existing …

One of the important features of polymethine (cyanine) dyes is isomerization about one of C–
C bonds of the polymethine chain. In this review, spectral properties of the isomers …

Although clay-based nanocomposite hydrogels have been widely explored, their instability
in hot water and saline solution inhibits their applications in biomedical engineering, and the …

Features such as color, brightness and fluorescence are extremely important in applications
of pigments. Hybrid materials inspired by the ancient Maya Blue pigment are a promising …

Flavylium cations are synthetic analogues of anthocyanins, the natural plant pigments that
are responsible for the majority of the red, blue, and purple colors of flowers, fruits, and …

The control over intermolecular interactions between chromophores at nanomaterial
interfaces is important for sensing and light-harvesting applications. To that aim, inorganic …

This paper investigates water sorption and dehydration of model synthetic clay (Laponite)
and highlights the large differences with natural Na-smectite clays. Measurements were …

Novel displays based on electrochemical reactions have significant potential for various
applications. In this study, a layered clay compound was used to immobilize a luminescent …

Surface-fixation induced emission is a fluorescence enhancement phenomenon, which is
expressed when dye molecules satisfy a specific adsorption condition on the anionic clay …

Interaction of organic dyes with layered silicates can cause various changes in dye
properties, such as metachromasia (color change), fluorescence quenching, resonance …
