Synthesis of Donor-Acceptor Gridarenes with Tunable Electronic Structures for Synaptic Learning Memristor

Abstract

A series of donor-acceptor ""-shaped gridarenes were synthesized with BT units as the crossbeam and thiophene units as the π-bridge. The donor-acceptor gridization functional effects on optoelectronic properties were then studied experimentally and computationally to provide a platform to adjust the energetics of the highest occupied molecular orbital/lowest unoccupied molecular orbital levels. Finally, G-DTh-based two-terminal memristor indium tin oxide/G-DTh:TBAPF 6 /Al successfully realizes conventional learning processes, synaptic potentiation, and depression plasticity which are essential for neuromorphic computation.
