Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 14338-32-0, Name is 2-Chloro-1-methylpyridinium iodide, molecular formula is C6H7ClIN, belongs to pyridine-derivatives compound, is a common compound. In a patnet, author is Barick, Barun K., once mentioned the new application about 14338-32-0, Application In Synthesis of 2-Chloro-1-methylpyridinium iodide.
Tin oxide nanostructure fabrication via sequential infiltration synthesis in block copolymer thin films
Tin oxide (SnO2) nanostructures are attractive for sensing, catalysis, and optoelectronic applications. Here we investigate the fabrication of SnOx nanostructures through sequential infiltration synthesis (SIS) in block copolymer (BCP) film templates. While the growth of metal and metal oxides within polymers and BCP films via SIS has been demonstrated until now using small precursors such as trimethyl aluminum and diethyl zinc, we hypothesize that SIS can be performed using larger precursors and demonstrate SnOx SIS with tetrakis(dimethylamino)tin (TDMASn) and hydrogen peroxide. Tuning the SIS reaction and BCP chemistry resulted in highly ordered, polystyrene-block-poly(2-vinyl pyridine) (P2VP)-templated porous SnOx – AlOx and SnOx nanostructures. Detailed investigation using in-situ microbalance, high resolution electron microscopy, elemental analysis and infra-red spectroscopy shows that SnOx can directly grow within P2VP homopolymer and BCP films. Simultaneously with the growth, SnOx SIS process also contributes to the polymer etch. Performing SnOx SIS with pretreatment of a single AlOx SIS cycle increases the SnOx growth and protects the BCP template from etching. This is the first report of SnOx SIS opening a pathway for additional tetrakis-based organometallic precursors to be utilized in growth processes within polymers. (C) 2019 Elsevier Inc.
