  • The chemical sensor plays an essential role in the fields of environmental conservation and monitoring, disaster and disease prevention, and industrial analysis. A typical chemical sensor is a device that transforms chemical information in a selective and reversible way, ranging from the concentration of a specific sample component to total composition analysis, into an analytically useful signal.

  • While it has been demonstrated that these materials have good sensitivity to polar VOCs, such as alcohols and acetone, 11,12 their rather poor response to nonpolar analytes has been viewed as a major drawback. In this report, we explored two ways to improve the sensor performance of regioregular polythiophene. The first approach is to add a second polymer at the end of the polythiophene chain to form a block copolymer. This second polymer interacts with the analytes in different ways, thus adding another dimensionality to the sensing response of the material.
