To achieve the full potential of scalable and cost-effective organic electronic devices, developments are being made in both academic and industry environments to move toward continuous solution-processing techniques that make use of safe and environmentally benign “”green”” solvents. In this work, the first example of a transistor device that is fully solution processed using only green solvents is demonstrated. This achievement is enabled through a novel multistage cleavable side chain process that provides aqueous solubility for semiconducting conjugated polymers, paired with aqueous inkjet printing of PEDOT:PSS electrodes, and a solution deposited ion gel electrolyte as the dielec. layer. The resulting organic electrochem. transistor devices operate in accumulation mode and reach maximum transconductance values of 1.1 mS at a gate voltage of – 1 V. Normalizing the transconductance value to the channel dimensions yields gm/W = 2200 S m-1 (μC* = 22 F cm-1 V-1 s-1), making these devices suitable for a range of applications requiring small signal amplification such as transistors, biosensors, and ion pumps. This new material design and device process paves the way toward scalable, safe, and efficient production of organic electronic devices. In the experiment, the researchers used many compounds, for example, Diethyl 2-methylmalonate(cas: 609-08-5Quality Control of Diethyl 2-methylmalonate)
Diethyl 2-methylmalonate(cas: 609-08-5) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.Quality Control of Diethyl 2-methylmalonate
