A series of sulfobetaine N ‐chloramines, covalently combining an N ‐chloramine unit and a sulfobetaine unit with varied intercharge linkers, were chemically synthesized. Preliminary antibacterial tests showed that the antibacterial activity decreased as the methylene linker increases from ‐(CH 2 ) 2 ‐ to ‐(CH 2 ) 8 ‐ except the linker of ‐(CH 2 ) 6 ‐, which exerted remarkable bactericidal efficacy unusually. In addition, the analogue with the linker of ‐(CH 2 ) 10 ‐ displayed the highest bactericidal efficacy among all synthetic N ‐chloramines, probably due to its neutral zwitterionic characteristic on structure. Our research provided highly efficacious antibacterial agents together with the vital references to design novel ionic N ‐chloramine biocides.
