“…Yang's group fabricated a SP derivative (TDBA‐SP) doped PDMS film with reversible photochromism and mechanochromism. [ 36 ] They further added SP into hydrogen‐bonded organic frameworks (HOFs) taking advantage of solvent adsorption method and liquid‐assisted grinding method, and subsequently mixed the as‐obtained product with PDMS to form the color‐changing flexible film showing excellent fatigue resistance and mechanical strength. Under irradiation, FRET occurred between HOFs and MC isomer converted from SP, causing the change of fluorescence emission from yellow‐green to orange and then to red.…”

In the past few years, fluorescent materials have received significant attention due to their fascinating luminescent properties and wide-ranging applications. Polydimethylsiloxane (PDMS) has also attracted the interest of many researchers due to its remarkable performances. The combination of fluorescence and PDMS will undoubtedly produce abundant advanced multifunctional materials. Although numerous achievements have been made in this field, there is still no review to summarize the relevant research. This review summarizes the state-of-the-art achievements made in PDMS-based fluorescent materials (PFMs). First, the preparation of PFM is overviewed following a classification according to the fluorescent sources, including organic fluorescent molecules, perovskite, photoluminescent nanomaterials, and metal complexes. Their applications in sensors, fluorescent probes, multifunctional coatings, and anticounterfeiting are then introduced. Finally, the challenges and development trends in the field of PFMs are presented.

“…PDMS has been widely used as a typical elastomer in aerospace, smart skin, electronic devices, special coatings, and medical devices due to the excellent biocompatibility, high- and low-temperature resistance, solvent resistance, weather resistance, and low dielectric constant. − The fluorescent elastomers formed by introducing a fluorescent chromophore into PDMS show some interesting fluorescence changes under strain: e.g., luminescence intensity and fluorescence color. − Therefore, these fluorescent PDMS materials hold promising application potentials as strain sensors and in encryption devices. In view of the substantial practical utility of elastomers including PDMS, chiral and CPL-active elastomers deserve much more attention.…”

Chiral and circularly polarized luminescence (CPL) materials with multiple stimuli responses have become a focus of attention. Meanwhile, elastomers have found substantial applications in a wide variety of fields. However, how to design and construct chiral elastomers, in particular CPL-active elastomers, still remains an academic challenge. In the present study, chiral helical substituted polyacetylene is chemically bonded with polydimethylsiloxane (PDMS) by hydrosilylation to form a chiroptically active elastomer. A CPL-active film was further fabricated by adding achiral fluorophores. Compared with the corresponding chiral helical polymer, the chiral films show much enhanced thermal stability in terms of chiroptical properties. The films also demonstrate reversible tunability in optical activity and CPL property when being subjected to a stretching−restoring process and exposed to a solvent like toluene. Further, noticeable chiral amplification is observed when the chiral PDMS film is superimposed with a pure PDMS film. This interesting finding is proposed to be due to the photoreflectivity of PDMS. This study provides an alternative strategy to exploit novel CPL-active elastomer materials with multiple stimuli responsivity and tunability, which may open up new opportunities for developing novel chiroptical devices.

“…In the past two decades, many organic units, including diarylethenes, azobenzenes, spiropyrans, and stilbene, have been developed as core skeletons to construct photosensitive materials. [9][10][11][12][13][14][15][16] The important photochemical reactions, including Z/E isomerization, photocyclization, and photodimerization, are identified as promising entry points for developing organic photoresponsive molecules. [17][18][19][20][21][22][23] However, most of the reported organic materials show only one responsible photosensitive feature under irradiation, which greatly limits their practical application.…”

Dual-stimuli response of spiropyran derivative modified by long-chains: high-contrast photochromism and mechanochromism

Abstract: In solid state, due to insufficient conformational freedom in the process of isomerization, spiropyrans exhibit reversible photochromism and mechanochromism are quite rare. Herein, a spiropyran derivative (TDBA-SP), which combines high...
