Circularly Polarized Light-Responsive Flexible Synapses Based on Supramolecular <i>n</i>-Type Chiral Organic Single Crystal/<i>p</i>-Type Polymer Heterojunctions.

ABSTRACT: Chiral neuromorphic devices that detect both circularly polarized light and digitized electrical signals are cutting-edge combinations of neuromorphic engineering and chiral optoelectronics that may advance both computing and sensing. In this work, organic electrochemical transistors (OECTs) based on n-type 2D organic single-crystal/p-type polymer heterojunctions are described. The supramolecular characteristics and molecular packing modes of the single crystals endowed the system with a high polarization selectivity. Furthermore, the integration of a p-n heterojunction facilitated modulation of charge trapping and separation at the interface, leading to improved chiroptical sensitivity. The devices emulate key features of biological synapses, including paired-pulse fa
