Spiropyran-based dynamic materials

Chem. Soc. Rev., 2014
In the past few years, spiropyran has emerged as the molecule-of-choice for the construction of novel dynamic materials. This unique molecular switch undergoes structural isomerisation in response to a variety of orthogonal stimuli, e.g. light, temperature, metal ions, redox potential, and mechanical stress.

Thermally Bistable Stiff Stilbene Photoswitches and Polymer Applications

The Chemical Record, EarlyView.
Thermally stable photoswitches offer new opportunities for controlling polymer structures and functions under nonequilibrium conditions. This Personal Account highlights stiff stilbene (SS) and sterically hindered stiff stilbene (HSS) photoswitches, which combine large structural changes with exceptional thermal bistability.

Oxygen‐Acceptor‐Driven High Photochromic Contrast Solid‐State Excited‐State Intramolecular Proton Transfer Photoswitches

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
The excited‐state intramolecular proton transfer (ESIPT) photoswitch tpmSA, which features an oxygen−acceptor, exhibits higher photochromic contrast (ΔE*Lab>74) than its nitrogen‐acceptor Schiff base analogues (ΔE*Lab<30). Theoretical calculations indicate that tpmSA effectively suppresses GSIPT, thereby enhancing the contrast.

Engineering Processing of Metal–Organic Frameworks: From Porous Crystals to Processable Composites

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
This review highlights engineering processing strategies for metal–organic frameworks (MOFs), including particle engineering, membrane fabrication, and surface coating. By correlating shaping pathways, interfacial organization, pore preservation, and scale‐up processability, it establishes a structure–interface–performance framework for transforming ...

Investigating nano-structured domains within ionic liquids: the effect of cation change on thermal equilibrium and relaxation of spiropyran and spirooxazine. [PDF]

, 2009
The established belief that ionic liquids (ILs) behave as homogenous solvents such as that observed in molecular solvents has been challenged.1, 2 Previous use of solvatochromic probe dyes has allowed for the traditional parameter of ‘polarity’ to be ...

Quantifying Dual‐Color Photopolymerization in Xolography via Raman Spectroscopy

Journal of Polymer Science, Volume 64, Issue 10, Page 1998-2008, 15 May 2026.
A dual‐wavelength Raman spectroscopy workflow is presented for the quantitative assessment of dual‐color photoinitiators. Contrast and efficiency parameters are extracted from in situ curing curves and spatial Raman mapping is used to find inhomogeneities in printed objects.
