Cover Feature: Synthesis and n‐Type Semiconducting Properties of Bis(dioxaborin) Compounds Containing a π‐Extended 2,2′‐Bithiophene Structure (Chem. Asian J. 3/2022)

Abstract

Looking at crystal structures makes us feel as if we are in a museum. Molecules are self-assembled to form beautiful crystal structures. Herein, bis(dioxaborin) compounds containing 2,2′-bithiophene derivatives were synthesized as n-type semiconductors for organic field-effect transistors (OFETs). An OFET fabricated using one of these compounds having a layer-by-layer crystal structure exhibited n-type semiconductor behavior with a low threshold voltage. This OFET performance was studied by theoretical calculations based on the crystal structure. More information can be found in the Full Paper by Katsuhiko Ono et al.
