Published: Aug. 18, 2022

With the rapid development of optoelectronic fields, electrochromic (EC) materials and devices have received remarkable attention shown attractive potential for use in emerging wearable portable electronics, electronic papers/billboards, see-through displays, other new-generation due to advantages low power consumption, easy viewing, flexibility, stretchability, etc. Despite continuous progress related determining how make electrochromics truly meet requirements mature displays (e.g., ideal overall performance) has been a long-term problem. Therefore, commercialization relevant high-quality products is still its infancy. In this review, we will focus on EC including two mainstream display prototypes (segmented pixel displays) their commercial applications. Among these topics, materials/devices, performance, construction approaches, processing techniques are comprehensively disscussed reviewed. We also outline current barriers with possible solutions discuss future field.

Published: Dec. 15, 2022

In this work, a series of novel multistimulus-responsive lanthanide coordination polymers {[LnL(H2O)4]Cl3·3H2O}n (Ln = Dy, Tb, Eu) constructed using dicarboxylic acid viologen derivative L (L N,N'-4,4'-bipyridiniodipropionate) and LnCl3·6H2O were prepared. All materials showed positive responses to UV light, the photochromic phenomena accompanied by significant photoquenching photoluminescence could be observed through photoelectron transfer mechanism. Strikingly, Dy analogue displayed photomagnetic behavior, as well responded positively small molecules inorganic ammonia/organic amines. Furthermore, good photoresponsive ammonia/amine vapor-responsive properties Dy-based material further fulfilled in dual-function papers involving erasable inkless printing visual amine detection applications. This work aims advance development multifunctional incorporating derivates versatile ions enriches research field.
