Molecular Engineering of a Conductive Metal-Organic Framework for Ultrasensitive, Rapid, Selective, and Reversible Sensing of Nitric Oxide.

ABSTRACT: The selective, sensitive, low power, and portable detection of nitric oxide (NO) is important for environmental monitoring, industrial safety, and medical diagnostics. While tremendous progress has been made in detecting NO, existing technologies exhibit significant trade-offs in sensitivity, selectivity, portability, and power requirements for broad implementation. This paper presents the first synthesis of a novel class of two-dimensional conductive tetrapyrazinoporphyrazine-based metal-organic frameworks (MOFs) interconnected with Cu (DC-100 and DC-102) and Zn ions (DC-101) with unprecedented chemiresistive performance toward NO detection. DC-100 achieves an ultralow detection limit (0.47 parts-per-trillion (ppt)), rapid response (within seconds), high select
