Photoresponsive 2D polymeric Langmuir–Blodgett films of 2,3,6,7,10,11-hexaiminotriphenylene

Abstract

2,3,6,7,10,11-Hexaiminotriphenylene (HATP) was connected via aerobic oxidative coupling to form large-area polymeric 2D films using the Langmuir–Blodgett technique. These 2D polymers exhibited electronic transport properties as a p-type semiconductor with high conductivity (0.91 S cm⁻¹), a high on/off current ratio (10³), and a photo-responsivity (980 nm) up to 160 mA W⁻¹.
