Based on triphenylamine (TPA) and aromatic diamines, two multifunctional donor–π–acceptor (D−π–A) conjugated poly-Schiff bases (PSBs) were synthesized subsequently tested analyzed. The aforementioned PSBs exhibit electrochromic (EC) electrofluorochromic (EFC) features can be utilized as cathode electrode materials for aqueous Zn-ion batteries (AZIBs). Both polymer films, PTTB-1 PTTB-2, show good EC EFC properties, excellent dissolution processability, thermal stability, reversible yellow-to-violet color changes in the UV–vis region. Between them, better optical contrast (46%), a fast response time (2.8 s/8.2 s), high coloring efficiency (CE = 310 cm2 C–1), cycling stability (10% attenuation over 2000 s of cycling) are all displayed by PTTB-2 polymer. present properties solvatochromic effects.

Tuning Spatially Resolved Shape Memory Effects of Stimuli‐Responsive Macroporous Photonic Crystals

Advanced Engineering Materials, Год журнала: 2024, Номер 26(16)

Stimuli‐responsive photonic crystals with patterned microstructures are of great interest in developing reconfigurable nano‐optical devices. Leveraging unconventional all‐room‐temperature shape memory efforts and spatially resolved photopolymerization, herein, a facile method for micropatterning stimuli‐responsive is reported. Macroporous polymer (SMP) fabricated by colloidal templating can be deformed cold programming, triggering the disappearance their original structural colors. Exposure samples to UV light through photomask selectively disables capabilities UV‐exposed regions. Hidden micropatterns defined revealed exposing colorless SMP films ethanol vapor, which triggers recovery “memorized” ordered corresponding Extensive nanoindentation experiments indicate that exposure increases crosslinking density enhances elastic modulus toughness exposed regions factor ≈2.0 ≈5.2, respectively. Due formation these extra crosslinks configuration, they prevent normal behavior where strained chains rearrange from temporary permanent configuration when triggered an external stimulus. This simple technology enable multistimuli‐responsive nanophotonic devices chromogenic anticounterfeiting labels.
