“…The optoelectronic effects in semicrystalline conjugated polymers depend sensitively on chain order and the way crystalline domains are interconnected and oriented . 1D nanostructures such as nanowires, nanotubes, nanofibers, nanowire shish‐kebab (NWSK) structures, micro/nano conductive–dielectric channels, needle‐like lamellae, and sandwiched conductive–dielectric–conductive structures have attracted particular attentions due to their unique electronic and optical properties.…”

Highly uniform and conductive single crystals of poly(3‐hexylthiophene) (P3HT)‐based homo and block copolymers with the end coily blocks of polystyrene, poly(methyl methacrylate), and poly(ethylene glycol) are developed using self‐seeding method from varied quality solvents. Edge‐on and flat‐on orientations are detected depending on the thickness and width of single crystals. Coily blocks are excluded from the P3HT crystalline structures, leading to brush‐like or hairy regions on surface of grown single crystals in the longitude of P3HT chains. The larger single crystals possessing flat‐on orientation are obtained from weaker solvents at higher seeding temperatures. The longer P3HT chains are folded, however, the shorter backbones are laminated on each other. The highest backbone lamination occurs for homo‐P3HT7150 (Mn of P3HT = 7150 g mol−1) single crystals grown at 20 °C from anisole, the weakest employed solvent. In contract, highly ordered and folded hairy single crystals are acquired from better solvents and high molecular weight P3HTs. In these conditions, the crystallographic features of the hairy block copolymer single crystals are similar to those of nonhairy homo‐P3HT ones. The coily brush‐covered P3HT48 800 single crystals have more foldings compared to the homo‐P3HT48 800 ones, whereas only two laminated backbones in shorter P3HT blocks are detected.

“…Figure 1 a shows a schematic diagram of the electrospining process for the continuous fiber. Since the precursor concentration is known to strongly influence electrospinnability of the compounds [ 24 , 36 ], various polymer concentrations were tested to determine an optimized viscoelastic behavior of the solution, while the morphology and fiber diameter of electrospun fibers were also influenced by voltage, distance between the needle and target, as well as the solvent. In all of the experiments, by using a high voltage supply, the applied voltage to the metal needle tip is 15 kV.…”

“…The exploitation of suitable deposition methods is crucial to exploit the potentiality of metallopolymers. Electrostatic or electro-spinning can be used to reduce polymer fiber diameters [ 20 , 21 ], and has been used to process fibers for various applications in fields such as energy, healthcare, and environmental engineering [ 22 , 23 , 24 ]. In fact, electrospun fibers also have become a promising versatile technology for the separation of emulsified oil/water mixtures because of the high specific surface areas, interconnected open pore structure, and the potential to incorporate active chemistry on nanosurfaces [ 25 , 26 ].…”

Electrospun fibers possessing π-conjugated backbones and π-conjugated semiconductor polymers are expected to offer potential utility in developing photoluminescent materials and functional fabrics for smart textiles, opto- and nanoelectronic, as well as piezo- and thermoelectric generators [ 24 , 27 , 28 , 29 ]. In this study, we discuss the synthesis of electrospun nanofibers composed of cobalt-containing polysilazane with a large diameter and a continuous-fiber electrostatic spinning method.…”

Emission in the nanostructured materials is important in micro/nanoelectronic devices. We report here a strategy for the processing of micron and submicron fibers from a cobalt-containing hyperbranched polysilazane by electrospinning. The electrospun nanofibers have uniform average diameters of~600 nm and lengths of~10 µm. The photophysical properties of polycobaltsilazane (PCSN) are studied using UV-VIS and photoluminescence spectroscopies. PCSN fibers display a series of emission peaks between 490 and 615 nm. The Co(II) doping into polysilazane leads to the emission from 465 to 415 nm. The emission wavelength shift of Co(III)-containing polysilazane is specific under 340 and 470 nm excitation wavelengths, respectively, while it is not observed with metal-free polysilazane. Thermogravimetric analysis-Differentical thermal analysis (TGA-DTA) profiles also show good thermostability of the PCSN fibers at 800 • C under Ar atmosphere. The use of PCSN offers both enhanced ceramic yields against~5 wt % starting material and the fluorescence intensity of polymeric fibers.

“…Co-solvent utilization improved the highly ordered homogenous fibers with a smoother morphology. Addition of low vapor pressure co-solvent effectively retards the thermodynamic driving force for liquid-liquid phase separation that modifies the solidification of the nanofibrous membranes (NFMs) [51]. Furthermore, temperature and relative humidity % can have an adverse effect on the spun nanofibers.…”

Conjugated copolymers (CCPs) are a class of polymers with excellent optical luminescent and electrical conducting properties because of their extensive π conjugation. CCPs have several advantages such as facile synthesis, structural tailorability, processability, and ease of device fabrication by compatible solvents. Electrospinning (ES) is a versatile technique that produces continuous high throughput nanofibers or microfibers and its appropriate synchronization with CCPs can aid in harvesting an ideal sensory nanofiber. The ES-based nanofibrous membrane enables sensors to accomplish ultrahigh sensitivity and response time with the aid of a greater surface-to-volume ratio. This review covers the crucial aspects of designing highly responsive optical sensors that includes synthetic strategies, sensor fabrication, mechanistic aspects, sensing modes, and recent sensing trends in monitoring environmental toxicants, pH, temperature, and humidity. In particular, considerable attention is being paid on classifying the ES-based optical sensor fabrication to overcome remaining challenges such as sensitivity, selectivity, dye leaching, instability, and reversibility.
