Article Abstract
Herein, we report the design and green synthesis of stereodefined tetrasubstituted alkenes (TPA-V-S, TPA-V-SO, and TPA-V-SO2) bearing a triphenyl amine (TPA) and a sulfenyl or sulfoxide, or sulfone functional group situated in the anti-orientation and two phenyl rings anti to each other. Notably, TPA-V-S exhibited reversible vis-to-NIR electrochromism with a high optical contrast of 70.6%, suitable for transparent-to-black (TTB) smart window applications. Additionally, the electrochromic smart window effectively decreased the solar heat gain by 82% in the black state.

Buildings are increasingly being conceived as dynamic systems that interact with their surroundings to optimize energy performance and enhance occupant comfort. This evolution in architectural thinking draws inspiration from biological systems, where the building envelope functions like a thermally responsive "skin" that can autonomously adjust its optical and thermal properties in response to environmental temperature changes. Among the many approaches developed for smart building envelopes, passive thermoresponsive spectral modulation systems have attracted growing interest due to their structural simplicity and low energy demand.

This study introduces the HydroTherm-Flow Smart Window (HTF Window), the first groundbreaking integration of thermochromic windows and Fe-Cr redox flow batteries (Fe-Cr RFBs), achieving dual functionalities of dynamic solar modulation-via dual-band (visible + near-infrared, NIR) modulation-and high-efficiency energy storage in a single component. Leveraging tunable hydroxypropyl cellulose (HPC) hydrogels, it enables ultrafast optical switching and autonomous nighttime opacity, overcoming the slow response and privacy limitations of conventional thermochromic systems. By repurposing the window as a compact electrolyte reservoir, it reduces the RFB spatial footprint while enhancing ionic conductivity by 30% via hydrogel "ion highways," achieving 77% energy efficiency with a 40% reduction in the solar heat gain coefficient.

Passive daytime radiative cooling (PDRC) offers a sustainable solution to global energy challenges by dissipating heat without energy input. However, conventional PDRC materials face trade-offs between biodegradability, color integration, optical transparency, and mechanical robustness. Herein, a biomimetic, structurally colored PDRC film fabricated via evaporation-induced self-assembly of cellulose nanocrystals (CNCs), betaine, and polyvinyl alcohol was developed.

The development of "smart" polymers capable of responding to physiologically relevant stimuli is essential for engineering dynamic sensing and actuation systems that leverage biological signals under specific (patho)physiological conditions. In this study, we present a general and versatile strategy to engineer novel stimuli-responsive behaviors in temperature-responsive protein-based polymers (PBPs) site-specific conjugation with self-immolative molecules. Specifically, we developed hydrogen peroxide (HO)- and β-galactosidase (β-gal)-responsive elastin-like polypeptides (ELPs) and resilin-like polypeptides (RLPs).

Hydrogel electrolyte-based electrochromic devices (ECDs) have become a research frontier in the electrochromic community as hydrogels combine the advantages of both liquid and solid electrolytes. However, these ECDs still require external power to operate. In addition, the color change is induced by cations insertion/extraction, accompanying anions accumulation at electrode-electrolyte interface, which may reduce the lifespan of ECDs.
