New lanthanide cryptates [LnL]（ClO4）3 （Ln=Eu 3+, Ce 3+, Pr 3+, Sm 3+, Gd 3+, Tb 3+; L=1, 4, 12, 15, 18, 26, 31, 39, 42, 43, 44-undecaazapentacyclo-[13.13.13.1 6, 10.1 20, 24.1 33, 37]-tetratetraconta-4, 6, 8, 10（44）, 11, 18, 20, 22, 24（43）, 25, 31, 33, 35, 37（42）, 38-penta decaene） were synthesized by transmetalation reaction of lanthanide perchlorates with its barium cryptate which was obtained by [2+3] template condensation of tren with 2,6-diformylpyridine in the presence of barium perchlorate, and characterized by elemental analysis, IR and electrospray mass spectrum.
