A series of three anthracene anchored dipodal chromogenic sensors appended with hydroxyl groups with different arrangements with respect to each other i.e., ortho (1), meta (2) and para (3) have been synthesized and evaluated as F- and CN- ion sensors. These sensors show variation in their selectivity response i.e. (1) equally responds to F- and CN- ions, (2) mainly responds to F- ion with slight interference from CN- while (3) totally discriminates between the two, being highly selective to F- ions only. This selectivity has been attributed to the acid-base phenomenon which affects reactivity, sensitivity and selectivity of the sensors.
