一般說明

六甲基二硅烷(HMDS)是稳定有效的氢不稳定类物质的三甲基硅烷化反应试剂,如醇、胺和脂肪酸。常用于在化学合成时保护敏感的官能基团。因其低成本、高蒸气压和安全性,广泛用作化学气相沉积(CVD)反应前体。

應用

六甲基二硅烷(HMDS)可用于:
  • 作为硅烷化剂,用于近中性条件下醇类的三甲基硅烷化反应。
  • 在α-氨基酸N-羧基酸酐的开环聚合反应中控制多肽分子量。
  • 通过等离子体增强化学气相沉积(CVD)制备碳氮化硅薄膜。
  • 用于扫描电镜的标本制备,以及羟基化合物制备三甲基硅醚。

特點和優勢

  • 强化学稳定性和低分子量
  • 无毒性的实惠试剂
  • 硅烷化反应的唯一副产物只有氨
  • HDMS硅烷化反应近中性,无需采取任何特别措施

A hard disk drive (HDD) is a data storage device that stores digital information by magnetizing nanosized magnets on flat disks and retrieves data by sensing the resulting magnetic field.

Spin-based electronic (spintronic) devices offer significant improvement to the limits of conventional charge-based memory and logic devices which suffer from high power usage, leakage current, performance saturation, and device complexity.
