The reaction of 2‐heteroaryl‐substituted trimethinium salts (A, B, and C) with aromatic 1,2‐diamines ( a , b , c , d , and e ) in acetonitrile/acetic acid leads to 6,13‐disubstituted 1,4,8,11‐tetraaza[14]annulene derivatives ( 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 ). The UV–vis spectral behavior of these compounds was examined in acetonitrile. Elemental analysis, IR, 1 H‐NMR, 13 C‐NMR, and mass spectra confirm the molecular structure of the newly synthesized compounds.
