Single-Crystalline, Size, and Orientation Controllable Nanowires and Ultralong Microwires of Organic Semiconductor with Strong Photoswitching Property was written by Jiang, Lang;Fu, Yanyan;Li, Hongxiang;Hu, Wenping. And the article was included in Journal of the American Chemical Society in 2008.COA of Formula: C18H10N2 This article mentions the following:
Single-crystalline, precise size-controlled nanowires and ultralong microwires with lengths reaching several millimeters of 2-anthracen-9-ylmethylenemalonitrile were prepared in large scale by cast assembly. The size and d. of the nanowires and microwires could be controlled by simply adjusting the concentration of the compound in casting solutions More importantly, the formation of these nanowires and microwires showed no substrate and solvent dependence and was orientation controllable. Highly reproducible and sensitive photoresponse characteristics were observed in these nanowires and microwires. Fast and reversible photoswitchers based on multiple or individual single-crystal microwires were fabricated via “multi times gold wire mask moving” technique with switch ratio over 100. In the experiment, the researchers used many compounds, for example, 2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4COA of Formula: C18H10N2).
2-(Anthracen-9-ylmethylene)malononitrile (cas: 55490-87-4) belongs to nitriles. Nitrile function is a very important functional group because it can be manipulated to other functional groups such as carboxylic acid by hydrolysis or amine by reduction, respectively. In addition, Nitriles can react with alkynes, which leads to an increase in carbon chain length (carbocyanation).COA of Formula: C18H10N2
