“…Furan-based biopolymers have received considerable attention in recent years because of their great potential to replace petroleum-based plastics [11]. Organic Semiconductor Single Crystals [58,71,72] are also considered to be an important research topic, given they are "ideal candidates for the construction of high-performance optoelectronic devices/circuits" [55]. In this study, we reported the topochemical polymerization of a furan-based diacetylene (Furan-DA 1).…”

Crystal structure elucidations of bio-based polymers provide invaluable data regarding structure-property relationships. In this work, we achieved synthesis and Single Crystal X-ray Diffraction (SCXRD) structural determination of a new furan-based polydiacetylene (PDA) derivative with carbamate (urethane) functionality. Firstly, diacetylene (DA) monomers were found to self-assemble in the crystalline state in such a way that the polymerization theoretically occurred in two different directions. Indeed, for both directions, geometrical parameters for the reactive alignment of DA are satisfied and closely related with the optimal geometrical parameters for DA topochemical polymerization (d(1) = 4.7-5.2 Å, d(2) ≤ 3.8 Å, θ ≈ 45 • ). However, within the axis of hydrogen bonds (HB), the self-assembling monomers display distances and angles (d(1) = 4.816 Å, d(2) = 3.822 Å, θ = 51 • ) that deviate more from the ideal values than those in the perpendicular direction (d(1) = 4.915Å, d(2) = 3.499Å, θ ≈ 45 • ). As expected from these observations, the thermal topochemical polymerization occurs in the direction perpendicular to the HB and the resulting PDA was characterized by SCXRD.

“…In contrast to other polymers such as polyethylene and polypropylene, which have soft molecular chains that form lamellar crystal structures based on the folding chain model, most conjugating polymers pack into nanofibrillar crystal forms with rigid extended molecular chains. [17] PEDOT nanofibrillar crystals tend to be disordered at a mesoscale and to self-nucleate during removal of the PSS from a PEDOT:PSS complex. In order to obtain nanofibrillar crystals of PEDOT that are ordered over a long range, a template can be used to serve as a nucleating agent to induce the conformational sequence of PEDOT molecular chains along a 1D scale.…”

Packing conjugated conducting polymer chains into long-range order can significantly boost their carrier-transport properties, allowing the design and enhancing the performance of applications in next-generation flexible electronics, energy storage, etc. However, strategies for organizing molecular chains have hitherto been challenging and have been associated with poor reprocessability. This paper discusses the development and application of highly crystalline poly(3, 4-ethylenedioxythiophene) (PEDOT) nanofibers. These highly conductive PEDOT nanofibers possess welldefined quasi-one-dimensional topology combined with highly ordered molecular chain arrangements as a result of interface-induced morphological shaping followed by recrystallization induced by Cladophora cellulose. The nanofibers are also easily dispersible and able to be reprocessed in aqueous solution. The multiple functionalities of these PEDOT nanofibers are demonstrated by using them as building blocks for applications such as 1D assembled microfibers in an ultra-sensitive strain sensor, 2D papers for electrochemical energy storage, and 3D aerogels for simultaneous solar-thermal distillation and thermoelectricity generation. The methods discussed here can be the basis of a new avenue for regulating the molecular structure of, processing, and discovering applications for conjugated conducting polymers.

“…The individual nanowire FET exhibited a remarkable hole mobility of up to 24 cm 2 V −1 s −1 (Figure 8d,e), which is the highest reported value in polymer crystal FETs. 100 In addition, the polymer nanowire FETs showed high performance in photoresponsivity and photoswitching. Xiao et al demonstrated a distinct variation of polymer orientation between two thiophene-and thiazolecontained DPP-based polymers in nanowire crystals (Figure 8f).…”
