1,4,7-Triazacyclononane, known as "TACN" which is pronounced "tack-en," is an aza-crown ether with the formula (C 2 H 4 NH) 3. [ 1] TACN is derived, formally speaking, from cyclononane by replacing three equidistant CH 2 groups with NH groups. TACN is one of the oligomers derived from aziridine, C 2 H 4 NH. Other members of the series include ...
