Design of molecular recognition elements for environmental potentiometric sensors

Research output: Contribution to journalArticlepeer-review


The selectivity of a potentiometric sensor is generally derived from the nature of the molecular recognition element on which the sensor is based. Complex stability, orientation/preorganization, chemical composition, and steric effects all play important roles in governing the selectivity of recognition elements. Thus, a logical approach to custom design of recognition elements is imperative to achieving high sensor selectivity. Various strategies for attaining high sensor selectivity toward environmentally important species, especially anions, via rational design of molecular recognition elements are discussed.
