The Air-Stable P-Heterocyclic Biradical for OFET Devices

GRAPHICAL ABSTRACT

Abstract

p-Type organic field-effect transistor (OFET) property of the air-stable 1,3-diphosphacyclobutane-2,4-diyl was preliminarily characterized and discussed based on the physicochemical properties and the crystal structure.

Keywords:

• Biradicals
• open-shell singlet
• crystal structure
