We report the synthesis of new 1-substituted N -(anthracen-9-ylmethyl)-1 H -benzimidazol-2-amines and 1,2,3-trisubstituted 1 H -benzimidazolium chlorides containing anthracene fluorophores. Benzimidazol-2-amine derivatives exhibited high chemosensing activity toward Н + cations, but in neutral media – toward Zn 2+ and Cd 2+ cations. The quinoline-containing benzimidazolium chloride showed fluorogenic sensor properties toward F − and CN − anions. Authors: Karina S. Tikhomirova*, Ivan E. Tolpygin, Andrey G. Starikov, Maria A.
