Comparing apples and oranges: A chemoresistive sensor for ethylene can be obtained simply by mixing copper complex 1 with single‐walled carbon nanotubes. The resulting devices show sub‐ppm sensitivity and high selectivity towards ethylene. The utility of the sensor was demonstrated by following ripe...
