Physical understanding and determination of different analytes without the need for advanced additional equipment are highly important, which can be achieved by using stimuli-induced chromic materials. chemical incorporation responsive chromophores into polymers results in fabrication polymers. Chromic electrospun nanofibers prepared electrospinning technique, their stimuli-responsivity is improved due to high surface-to-volume ratio. This Perspective focuses on recent studies developments nanofibers. Within this Perspective, these divided classes photochromic, thermochromic, electrochromic, mechanochromic, halochromic, solvatochromic, hydrochromic, ionochromic according stimuli they respond. In addition, preparation methods, compounds, conditions, response mechanisms, applications will discussed. The main such food packaging sensors, health monitoring anticounterfeiting materials, ink-free rewritable media, smart clothing. Several new strategies also proposed future studies. multiresponsive that combine properties a single system multifunctional merge stimuli-responsive with other functionalities considered future. aims assist researchers scientists development applications, including multimode sensors packaging, shape memory-assisted dual-mode encryption important data.

An environmentally friendly smart ink was developed by incorporating fluorescein into functionalized poly(methyl methacrylate) (PMMA) nanoparticles synthesized using an emulsifier-free emulsion copolymerization approach. The functional comonomers of 2-(dimethylamino)ethyl methacrylate (DMAEMA), acrylamide, hydroxyethyl methacrylate, and glycidyl in 10 wt % with respect to methyl were used obtain the colloidal PMMA nanoparticles. Functional groups latex characterized Fourier-transform infrared spectroscopy. Field emission scanning electron microscopy results showed that all have nearly spherical morphologies variations size surface smoothness due presence different comonomers. Ultraviolet–visible fluorescence spectra indicated fluorescein-doped containing DMAEMA comonomer had highest absorbance intensity. In alkaline media, turns a dianion, showing red shift increased UV–vis addition, inductive characteristics tertiary amine result enhancing conjugation molecules increasing intensities. Therefore, formulation applications securing documents fingerprints, encrypting banknotes money, detecting latent crafting anticounterfeiting paper, eventually providing optical detection indication scratches.

Dual temperature- and photoresponsive polymer nanoparticles with sensitivity toward temperature variation through fluorescence resonance energy transfer (FRET)-assisted white light emission (WLE) were synthesized using distillation–precipitation polymerization. A chemosensor of temperature, light-emitting anticounterfeiting inks, different products for security encryption confidential documents prepared on the basis FRET mechanism due to an efficient spectral overlap between coumarin donor absorption rhodamine B (RhB) acceptor. At 150 μL RhB doping, a strong WLE was observed as consequence two complementary colors. Upon increasing in range 25–85 °C, distance affected squeezing thermoresponsive moieties response heating; thus, turned off. These stimulus-responsive fluorescent finally used sensors applications by incorporating on/off based preparation paper, silk, ink incorporation species into paper pulp, impregnation silk colloidal nanoparticles, adding poly(ethylene glycol) glycerol colloids, respectively.

Abstract Bistable electrochromic displays offer great potential due to their ability maintain both colored and colorless states while minimizing power consumption saving energy. In this research, the properties of organic small molecular leuco dyes are explored. Various fabricated using crystal violet lactone, cresol red, fluorescein, rhodamine b derivatives, based on proton‐coupled electron transfer mechanism. Considering switching time bistability, prototype devices such as anti‐counterfeiting displays, gate e‐papers, multi‐color colorful nature‐inspired flexible developed. Electrochromic bond cleavage/formation exhibit outstanding color efficiency (min: 206 cm 2 c −1 , max: 1163 ), rapid 0.1 s, dynamic responsivity), dual outputs (color emission), reversibility (150–200 cycles). The with strong memory multicolor responsiveness new possibilities for utilizing in design fabrication devices.
