Automation is vital to accelerating research. In recent years, the application of self-driving labs materials discovery and device optimization has highlighted many benefits challenges inherent these new technologies. Successful automated workflows offer tangible fundamental science industrial scale-up by significantly increasing productivity reproducibility all while enabling entirely types experiments. However, it's implemtation often time-consuming cost-prohibitive necessitates...
Abstract There is an increasing demand for low-cost and high-performance electronics which has stimulated a need new dielectric materials. We have developed facile synthesis of poly(2-(methacryloyloxy)ethyl trimethylammonium bis(trifluoromethylsulfonyl)azanide- ran -methyl methacrylate) (P(METATFSI-MMA)), polymeric ionic liquid that can be used as semiconducting single walled carbon nanotube (SWCNTs) thin film transistors (TFTs). The P(METATFSI-MMA) polymer was synthesized at both 35 62 mol%...
Despite the simplicity of drop-casting method to deposit films single-walled carbon nanotubes (SWNTs) for applications such as printed electronics, this technique presents many challenges and uncertainties that are yet be addressed. The coffee-ring effect is a known example, which results in an accumulation solids around edge drop. This can mitigated by increasing temperature substrate induce Marangoni flows, but it unknown what repercussions change would on dispersions conjugated...
A rise in demand for disposable consumer electronics such as smart packaging, wearable electronics, and single-use point-of-source sensors requires the development of eco-friendly compostable electronic materials. Chitosan is derived from crustacean waste offers high dielectric constant values without requiring rigorous purification, making it sustainable large-scale device manufacturing. When processed acidic media, protonated backbone chitosan pairs with counterions acid dissociation to...
The constant demands for better performance of consumer electronics has led to shorter usage lifespans, resulting in a significant increase electronic waste (e-waste). Developing which can be easily...
Carbon nanotube-based thin-film and electrolyte-gated transistors with environmentally benign dielectric materials can be fabricated on flexible substrates have potential for further development into wearable sensors.
Introduction of amidine groups within the side chains a conjugated polyfluorene was carried out using copper-catalyzed azide-alkyne cycloaddition. The resulting polymer shown to form strong supramolecular interactions with sidewalls single-walled carbon nanotubes (SWNTs), forming polymer-nanotube complexes that exhibited solubility in various organic solvents. It polymer-SWNT were responsive CO
Organic Thin Film Transistors In article number 2406105, Joseph G. Manion, Benoît H. Lessard, and co-workers summarize how their research group has adopted "hybrid automation" by using simple automatic electrical testers (autotesters) as a tool to increase productivity enhance reproducibility in OTFT research. The autotester enables acceleration through large parameter space created both diverse material roles device architectures.
In this paper, we report the design and synthesis of three naphthalene diimide- (NDI) anthraquinone- (AQ) based organic chromophores derived from direct arylation reactions; NDI-AQ, AQ-NDI-AQ NDI-AQ-NDI. Compared to classic cross-coupling reactions, method reduced number synthetic purification steps. The chemical structures, photophysical electrochemical properties these molecules were characterized using UV-vis spectroscopy, fluorescence emission spectroscopy cyclic voltammetry (CV)....
