论文题目:Nanoporous Carbon Aerogels for Laser-Printed Wearable Sensors

论文作者:Xiujie Ji, Ying Zhong, Chenyue Li, Junjun Chu, Hongqiang Wang, Zheng Xing, Tingting Niu, Zhihua Zhang, Ai Du

论文摘要:Laser-induced porous carbon materials have received growing attention as electrodes in micro-supercapacitors, electronics, and biosensors. Herein, resorcinol-formaldehyde (RF) aerogel is used for laser carbonization and activation to produce a nanoporous black conductive surface with high porosity and a specific surface area of 703 m2·g–1 as well as high absorbance to infrared light (~98%). Furthermore, inspired by the photoreception behavior of octopus arms, a “thunder motif” nanoporous carbon aerogel-based resistance-type sensor is able to be laser-printed on paper-reinforced RF aerogel, which shows high integration of temperature (0.19%·°C–1), strain (gauge factor 16.7), humidity, and especially infrared light (0.12%·mW–1, which is not common for a normal on-skin sensor) sensing in one device and better performance than a serpentine layout sensor. With its good flexibility and biodegradability, this multifunctional sensor can serve as an on-skin wearable sensor that can sense gesture changes and breathing.

论文题目:Dielectric materials for electrolyte gated transistor applications

论文作者:Wei Huang, Jianhua Chen, Gang Wang, Yao Yao, Xinming Zhuang, Robert M. Pankow, Yuhua Cheng, Tobin J. Marks, Antonio Facchetti

发表日期:14 August 2021

论文摘要:In this review, we summarize the recent progress in developing dielectric materials for electrolyte gated transistors (EGTs). Semiconductors for EGTs have been extensively studied and reviewed since they dominate the key transport properties of these types of transistors. However, the electrolyte dielectric component of these devices is equally important since it provides ionic displacement dominating the device capacitance, driving voltage, and switching times, and determines how to integrate EGTs in/with other device components. Thus, the development of electrolyte dielectrics not only improves the EGT performance but also enables new features and opens up new possibilities for EGTs. Liquid electrolytes are more suitable for integration at the bio-interface and in sensing applications, while solid electrolytes can be printable and are compatible with circuit monolithic integration. Moreover, understanding the mechanism of electrolyte dielectric gating has also accelerated the expansion of emerging electrolyte-based electric double layer transistors (EDLTs) and electrochemical transistors (ECTs). In this review, we first discuss the structure and operation of EDLTs and ECTs, for the latter particularly those based on organic semiconductors (OECTs), since they are the major users of these materials. Next, different types of electrolyte dielectric materials are discussed, driven by relevant applications. We complete this paper with a summary and an outlook of this field.

论文题目:Corannulene-based donor–acceptor-type conjugated polymers with electrochromic properties

论文作者:Jing-Ju Huang, Hsing-An Lin, Chi Chen, Po-Wen Tangc, Shyh-Chyang Luo  

发表日期:07 July 2021

论文摘要:π-Conjugated polymers have received increasing attention in electrochromic material research because their color change can be altered over a wide range by introducing electron-donor (D) and electron-acceptor (A) moieties. In this study, we have synthesized curved corannulene-based monomers with D and A moieties and applied them to prepare π-conjugated polymers to drive color switching. The absorption and emission properties of our conjugated polymers can be tuned by inserting D and A moieties into the conjugated backbone. Through this study, it has been demonstrated that corannulene-based conjugated polymers exhibit stable electrochromic properties with a high optical contrast ratio. Furthermore, emissions in the solid state and reversible electrofluorescence switching are observed in these polymers. This might be due to the inhibition of aggregation-induced quenching through the incorporation of nonplanar corannulene in the π-conjugated backbone. Based on these results, we consider corannulene-embedded π-conjugated polymers as a new π-conjugated system with versatile and tunable optical properties for application in modern optoelectronic devices.

论文题目:A molecular design principle towards luminescent polymorphic organic heterostructured architectures

论文作者:Qianqian Zhou, Yilong Lei, Hongbing Fu

发表日期:14 January, 2021

论文摘要:Polymorph-selective synthesis of organic heterostructured architectures represents a tough challenge due to the diversity of organic species and the growth complexity of seed crystals with specific polymorphs as well as complicated epitaxial relationships among diverse constituent materials. Herein, we employ three polymorphic π-conjugated molecules to construct three types of binary organic heterostructures based on a molecular design principle via a solution seeded-mediated strategy, where pre-existing crystals with a specific polymorph serve as seeds to afford epitaxial growth of another organic crystal. As a consequence, the crystal form of the second growth component can be exclusively determined regardless of the synthetic procedures. Indeed, epitaxial growth of these dual-color-emitting organic heterostructures was realized depending on the small lattice mismatch between two specific polymorphs of any two constituent materials, which is determined by their structural compatibility and elaborate selection of the seed crystals. The present work offers a promising platform to understand polymorph-selective synthesis of organic heterostructured microstructures, which may be used to achieve unprecedented photonic and electronic properties.

论文题目:Fast fabrication of double-layer printed circuits using bismuth-based low-melting alloy beads

论文作者:Pengju Zhang, Yang Yu, Bowei Chen, Wei Wang, Sijian Wei, Wei Rao, Qian Wang

发表日期:June 28, 2021

论文摘要:Low-melting metals are newly emerging functional materials with rather unique physical or chemical properties. This paper introduces a novel way of fast fabricating double-layer printed circuits using bismuth-based low-melting alloy beads. BiInSn printed lines solidify immediately when deposited on a substrate at room temperature, so no additional post-treatment is required after printing. Thus, the method saves the fabrication time of the printed circuits. The implementation of a double-layer circuit based on the BiInSn alloy is rapidly executed in turn by printing, aligning, bonding, drilling, and via-filling. In particular, the via-filling process can be carried out by directly injecting a molten BiInSn alloy under differential pressure. In this way, the connection between the vias and the printed lines devastatingly fits with the same printing material. The minimum width of the printed line can achieve 33 μm, resulting in the highest resolution printing technique to date with a bismuth-based alloy. This new method offers more simplicity, practicability, and functional diversity in electronic fabrication and benefits to efficiently realize stable double-layer circuit boards with more straightforward steps. Therefore, it has the potential to promote the development and application of low-melting metals in the field of printed electronics.
