Two approaches to the synthesis of polyazamacrocycles containing twobiphenyl and twopolyaminemoieties are described. The first route comprises the synthesis of N,N'bis(bromobiphenyl) substituted diand poly-amines by the reactions of 2.2-3 equivalents of 4,4'or 3,3'-dibromobiphenyls with corresponding diand polyamines followed by the reaction with a second molecule of the amine. The second approach
