• • c-MOFs achieve electrical conductivity tunable from semiconducting to metallic regimes, with values up to 10^3 S/cm reported for 2D conjugated frameworks, enabling low-power chemiresistive sensing at room temperature, a critical advantage over traditional metal-oxide sensors that require 200–500°C operation.
• • Structural design strategies, such as the 'rotor-stator' approach, yield highly crystalline 2D c-MOFs with enhanced charge mobility, as demonstrated in potassium-ion batteries achieving high specific capacity (e.g., 500 mAh/g at 0.1 A/g), indicating potential for high-rate sensing applications.
• • Metal coordination induced planarization in metallosalphen-based 2D c-MOFs enhances NO2 sensing performance, with detection limits reaching parts-per-billion levels (e.g., 0.5 ppm) and response times under 60 seconds, outperforming conventional polymer-based sensors.
• • Heavy chalcogen substitution (e.g., S, Se) in c-MOFs increases electrical conductivity by up to two orders of magnitude (from 10^-4 to 10^-2 S/cm), directly improving signal-to-noise ratios in electrochemical sensors, as evidenced by enhanced sensitivity in ascorbic acid detection.
