Abstract


We report the synthesis of new 1-substituted N-(anthracen-9-ylmethyl)-1H-benzimidazol-2-amines and 1,2,3-trisubstituted 1H-benzimidazolium chlorides containing anthracene fluorophores. Benzimidazol-2-amine derivatives exhibited high chemosensing activity toward Н+ cations, but in neutral media – toward Zn2+ and Cd2+ cations. The quinoline-containing benzimidazolium chloride showed fluorogenic sensor properties toward F and CN anions.
