Base-mediated condensation reaction of 2,7-dibromotropone with 3,6,12,15-tetraoxa-9-thiaheptadecane-1,17-dithiol afforded 1:1 and 2:2 condensates (4 and 5). Troponoid trithiocrown ether (4) was used as a carrier through a chloroform liquid membrane. However, the guest selectivity of 4 was lower than that of the corresponding dithiocrown ether derivative (1e).
