✦ Synopsis

A novel tripodal hexadentate ligand, consisting of three catechol units, three isobutenyl ether arms, and one aromatic core, was synthesized through four steps, in which the Claisen rearrangement was included as the key step. The hexadentate ligand formed a 1:1 complex with iron(III) trichloride hexahydrate with an equilibrium constant (conditional) of 6.3 x 104 M-1 in acetonitrile in the presence of 2,4,6-trimethylpyridine.

Tripodal hexadentate ligands, having three 8-hydroxyquinolyl or 2-methyl-8-hydroxyquinolyl groups as binding sites, were successfully prepared from the corresponding tris(isobutenyl 8-quinolyl ether) via the Claisen rearrangement. The 2-methyl-8-hydroxyquinolyl derivative exhibited binding ability f

A polymer having dibenzothiophenium salt moieties [poly(sulfonium salt), 2] was prepared by the reaction of poly(2-vinyldibenzothiophene) (1) with CH 3 I and AgBF 4 in CH 2 ClCH 2 Cl at room temperature for 24 h. The obtained polymer 2 was found to contain 71% of the methyldibenzothiophenium tetrafl
