A low onset voltage WORM type polymer memory based on functional PES was written by Fang, Jiyong;Zhang, Haibo;Wei, Wei;Li, Yunxi;Yue, Xigui;Jiang, Zhenhua. And the article was included in Journal of Applied Polymer Science in 2015.Application of 628-13-7 This article mentions the following:
A high-performance polymer polyethersulfone (CN-Azo-PES), with a flexible ethoxyl linkage between the azobenzene chromophore side chain and the PES backbone, was designed and successfully synthesized for an application in a WORM type memory device as an active polymer layer. CN-Azo-PES has excellent thermal properties with Tg of 151° and the degradation temperature >373°, which can contribute to a better performance of the device. The device based on CN-Azo-PES exhibits a write-once read-many (WORM) type memory performance with an onset voltage ≥-1.0 V and an ON/OFF current ratio >102 at a reading voltage of 0.4 V. Also, the data can be maintained for longer than 4 × 105 s once written and can be read for >400 cycles under a reading voltage of 0.4 V. Thus CN-Azo-PES can serve as an energy saving memory material in the data storage field of next generation. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42644. In the experiment, the researchers used many compounds, for example, Pyridinehydrochloride (cas: 628-13-7Application of 628-13-7).
Pyridinehydrochloride (cas: 628-13-7) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Application of 628-13-7
