Non-volatile organic transistor memory devices using the poly(4-vinylpyridine)-based supramolecular electrets†
Abstract
Supramolecular electrets consisting of poly(4-vinylpyridine) (P4VP) and conjugated molecules of phenol, 2-naphthol and 2-hydroxyanthracene were investigated for non-volatile transistor memory applications. The memory windows of these supramolecular electret devices were significantly enhanced upon increasing the π-conjugation size of the molecule. A high ON/OFF current ratio of more than 107 over 104 s was achieved on the supramolecule based memory devices.
