The absorption of light gives a pigment its colour and its reason for being, but it also creates
excited states, that is, new molecules with an energy excess that can be dissipated through …

Smart color-changing indicator films were prepared using two different types of cellulose
(CMC and CNF) and pH-sensitive dye, alizarin. pH-responsive color indicator films were …

Heritage materials are highly complex systems of unknown and intrinsically heterogeneous
compositions and unmonitored long-term modifications. In this microreview, we describe our …

An iron‐substituted tetraphenyl porphyrin bearing positively charged trimethylammonio
groups at the para position of each phenyl ring catalyzes the photoinduced conversion of …

Abstract Three novel molecules (AL-1, AL-2 and AL-3) were designed based on the
substitution of cyano group for hydrogen atoms at different positions on alizarin, and the …

Compositionally similar organic red colorants in the anthraquinone family, whose
photodegradation can cause irreversible color and stability changes, have long been used …

A simple and rapid distance paper-based analytical device (dPAD) for the detection of lead
(Pb) in foods is proposed herein. The assay principle is based on competitive binding …

Background Color change in artworks has been commented on for centuries. Fading of
watercolor pigments is a notable alteration. Pigments based on carminic acid are among …

By removing the effects of ensemble averaging and molecular aggregation, we untangle the
factors that govern the dispersive electron transfer kinetics of eosin-sensitized TiO2, focusing …

Fluorophores with controlled on–off switching properties and subcellular targeting abilities
are essential for modern super-resolution microscopy techniques. However, the effective …
