Co-Processing of [Fe(NH2trz)3](2ns)2 and UHMWPE into Materials Combining Spin Crossover and High Mechanical Strength

open access: yesSci, 2021
The coordination polymer [Fe(NH2trz)3](2ns)2 (NH2trz = 4-amino-1,2,4-triazole and 2ns− = counterion 2-naphthalene sulfonate) exhibits the rare phenomenon of spin crossover in an attractive temperature range, i.e., somewhat above room temperature.

Reversible Thermochromism and Halochromism of a Homoleptic Copper (II) Complex Containing Aminoethylethanolamine Ligand, and DFT Study [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2023
Two copper(II) complexes of general formula [CuL2]X2 where L= aminoethylethanolamine and X= ClO4- and Cl- were prepared with a relatively high yield. These complexes were characterized by elemental microanalysis, UV-Vis, and IR spectroscopy techniques ...

Thermochromic Infrared Metamaterials [PDF]

open access: yesAdvanced Materials, 2015
An infrared artificial thermochromic material composed of a metamaterial emitter and a bimaterial micro-electro-mechanical system is investigated. A differential emissivity of over 30% is achieved between 623 K and room temperature. The passive metamaterial device demonstrates the ability to independently control the peak wavelength and temperature ...

INFLUENCE OF SOLVENT HYSTERESIS IN THERMOCHROMIC OFFSET PRINTS ON THE THERMOCHROMISM EFFECT [PDF]

open access: yesCellulose Chemistry and Technology, 2023
"The colorimetric values of prints of three thermochromic offset inks on four different paper substrates – bulky, synthetic, filter (neat cellulose) and recycled in one heating-cooling cycle – were determined. Prints that are cooled are lighter than those that are heated at the same temperature. This phenomenon is a consequence of the hysteresis of the

Shutter luminous fibres based on rare-earth materials for real-time thermal response

open access: yesMaterials Research Express, 2020
Rare earth luminescent materials (RELMs) are commonly used in optics and products intended for safety and decoration. However, there is still a great challenge to alternate the emission performance after the RELMs are activated.

A Thermochromic Superhydrophobic Surface [PDF]

open access: yesScientific Reports, 2016
AbstractHighly enhanced solid-state thermochromism is observed in regioregular poly(3-hexylthiophene), P3HT, when deposited on a superhydrophobic polymer-SiO2 nanocomposite coating. The conformal P3HT coating on the nanocomposite surface does not alter or reduce superhydrophicity while maintaining its reversible enhanced thermochromism.

Optical nature of non‐substituted triphenylmethyl cation: Crystalline state emission, thermochromism, and phosphorescence

open access: yesAggregate, 2021
Since the discovery of the triphenylmethyl (trityl) cation 120 years ago, a variety of aromatic cations having various colors and luminescence properties have been rigorously studied.

Luminescent polyurethane composite with real-time thermal response via visible signal

open access: yesMaterials Research Express, 2021
Visible signals are vital to human communication. Thermal signals are often difficult to observe unless they are in physical contact with the subject or an infrared thermal imaging system is used.
