Abstract Nature provides much inspiration for the design of materials capable motion upon exposure to external stimuli, and many examples such active systems have been created in laboratory. However, achieve continuous driven by an unchanging, constant stimulus has proven extremely challenging. Here we describe a liquid crystalline polymer film doped with visible light responsive fluorinated azobenzene chaotic oscillatory when exposed ambient sunlight air. The presence simultaneous...
We report a novel way to modulate the elastic modulus of azobenzene containing liquid crystal networks (LCNs) by exposure light. The can cycle between different levels controlling illumination conditions. Exposing polymer network UV light near trans absorption band gives small reduction glass transition temperature thereby lowering modulus. addition blue addressing cis surprisingly amplifies this effect. continuous oscillatory effects trans-to-cis isomerization overrule overall net...
In this work, the application of a composite film polydiacetylenes (PDAs) with poly(vinyl alcohol) (PVA) is reported as an irreversible low-temperature indicator for frozen food and pharmaceutical items. The thermochromic dyes, i.e., functionalized diacetylenes (DAs), were synthesized using Steglich esterification 10,12-pentacosadiynoic acid different aliphatic alcohols (linear branched chains). PDAs show behavior at low temperatures (above 7 °C) because lack intermolecular interactions on...
Abstract Stimuli‐responsive materials with optical adaptibility to external triggers are versatile for diverse applications. Among these, smart chromic molecular photoswitching enable real‐time absorption changes indications, crucial sensing, security, sensors, authentication, and anti‐counterfeiting This current study presents an intriguing approach develop spiropyran (SP)‐based switches rapid reversible photochromism. Three dual‐responsive functional SPs (f‐SPs) dyes varying SP moieties...
The search to unravel the origins of life on Earth pivots recognizing environments capable synthesizing and preserving prebiotic organic molecules (chemical precursors biological systems). Prebiotic chemistry plays a crucial role in understanding origin Earth, terrestrial hydrothermal systems may offer suitable environment for its emergence. In this study, we investigated travertine deposit Puga hot spring Ladakh, India- site that not only mimics early but also shares similarities with...
Abstract The remarkable adaptability of chromogenic phases found in polymers like conjugated polydiacetylene (PDA) is especially noteworthy due to their vital role durable sensing applications. This study presents the synthesis and utilization PDA‐based functionalized dyes as a visual color indicator. These are developed by modifying head groups 10,12‐tricosadiynoic acid (TC) with aromatic alcohols, employing Steglich esterification. Confirmation dye derivative achieved using various...
The formation of amylose-polystyrene inclusion complexes via a novel two-step approach is described. In the first-step, styrene was inserted inside amylose helical cavity, followed by free radical polymerization in second step. were characterized attenuated total reflection fourier transform infrared spectroscopy (ATR-FTIR), ultraviolet (UV), X-ray diffraction (XRD), atomic force microscopy (AFM), and differential scanning calorimetry (DSC). polystyrene confirmed gel permeation...
The orientation changes of perpendicular cylindrical microdomains in polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) thin films upon annealing different solvent vapors were investigated by situ grazing incidence small-angle X-ray scattering (GISAXS) and ex scanning force microscopy (SFM). swelling P4VP cylinders (C⊥) chloroform, a non-selective vapor, leads to the reorientation in-plane through disordered state particular kinetic pathway phase diagram drying. On other hand, selective...
