Abstract 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.
