A series of podands bearing phenyl, naphthyl and anthryl end groups were prepared and characterized. UV-visible spectrophotometry was used to investigate the host-guest chemistry of the podands in complexation with tropylium tetrafluoroborate in 1,2-dichloroethane. The results, are discussed and compared with those for previously studied systems containing crown ethers. The stability constants for these open-chain polyethers are in the range 5,1-8,4 dm3 mol-1, except for the podand having anthryl end groups [1,12 bis(anthryl-9)-2,5,8,11-tetraoxadodecane], which gives a 10-fold increase in the stability constant.
