Influence of Binder Type on Color Characteristics of Cotton Fabric Colored with a Photochromic Colorant

Journal of Natural Fibers, 2018
Photochromic colorants change rapidly and reversibly from colorless to colored state when activated by ultraviolet radiation. They can be applied on textile substrates with use of organic binders.

Tuning the Negative Photochromism of Water-Soluble Spiropyran Polymers

, 2018
In aqueous media, negative photochromism can occur from cationic, protonated merocyanines (MCH+) to spiropyrans (SP) upon exposure to visible light. Herein, we demonstrate the uniquely simple manner in which polymers can tune the key properties of these ...

Useful Spectrokinetic Methods for the Investigation of Photochromic and Thermo-Photochromic Spiropyrans [PDF]

Molecules, 2008
This review reports on the main results of a set of kinetic elucidation methods developed by our team over the last few years. Formalisms, procedures and examples to solve all possible AB photochromic and thermophotochromic kinetics are presented. Also, discussions of the operating conditions, the continuous irradiation experiment, the spectrokinetic ...

A new approach to switchable photochromic materials by combining photochromism and piezochromism together in an AIE-active molecule

, 2017
Switchable photochromic material was achieved by combining photochromism and piezochromism together. The photochromic ON/OFF states can be easily controlled and indicated.
