Organic-inorganic hybrid covalent superlattice for temperature-compensated ratiometric gas sensing.

ABSTRACT: Room-temperature chemiresistive sensors are valued for their low power consumption, ease of operation, and real-time monitoring capabilities, making them highly advantageous for various applications. However, the challenge of inaccurate detection due to variations in operating temperature is a significant hurdle for their practical use. To address this, we develop a ratiometric-gas sensing method that leverages the exceptional photoelectric and chemiresistive gas sensing sensitivity of organic-inorganic hybrid superlattice materials AgBDT (BDT = 1,4-benzenedithiol). This approach can effectively detect nitrogen dioxide molecules, with a detection limit of 3.06 ppb. Crucially, the ratiometric-gas sensing technique offers robust diminution to temperature interference, with the coefficient of
