New non-volatile memory platform built with covalent organic frameworks
Researchers at Institute of Science Tokyo created a new material platform for non-volatile memories using covalent organic frameworks (COFs), which are crystalline solids with high thermal stability. The researchers successfully installed electric-field-responsive dipolar rotors into COFs. Owing to the unique structure of the COFs, the dipolar rotors can flip in response to an electric field without being hampered by a steric hindrance from the surroundings, and their orientation can be held at ambient temperature for a long time, which are necessary conditions for non-volatile memories.
