摘要:
摘要： A new donor‐acceptor‐acceptor (D‐A‐A) type of conjugated molecule, N‐(4‐(N′,N′‐diphenyl)phenylamine)‐4‐(4′‐(2,2‐dicyanovinyl)phenyl) naphthalene‐1,8‐dicarboxylic monoimide (TPA‐NI‐DCN), consisting of triphenylamine (TPA) donors and naphthalimide (NI)/dicyanovinylene (DCN) acceptors was synthesized and characterized. In conjunction with previously reported D‐A based materials, the additional DCN moiety attached as end group in the D‐A‐A configuration can result in a stable charge transfer (CT) and charge‐separated state to maintain the ON state current. The vacuum‐deposited TPA‐NI‐DCN device fabricated as an active memory layer was demonstrated to exhibit write‐once‐read‐many (WORM) switching characteristics of organic nonvolatile memory due to the strong polarity of the TPA‐NI‐DCN moiety. The early bird catches the WORM: A donor‐acceptor‐donor (D‐A‐A) type conjugated molecule based on linear π‐bridging triphenylamine (TPA) donors and naphthalimide (NI)/dicyanovinylene (DCN) acceptors was prepared and shown to possess nonvolatile WORM (write‐once‐read‐many) memory behavior. 其他題名： Chem.
