Li+ complexes of OH deprotonated calix[4]arene, caIix[6]arene, and calix[8]arene were prepared. The spectra of these complexes show that with Li+ ions the complex formation is complete. In the 1:4, 1:6, and 1:8 complexes, respectively, the Li+ ions are localized in their Li+ bonds since only a broad band was found in the FT-IR spectra. In the case of the corresponding 1:3, 1:5, and 1:7 complexes far-IR continua are observed in the region 380-150 cm(-1). These continua demonstrate that these Li+-bonded systems show large Li+ polarizability due to collective Li+ motion. This Li+ polarizability increases with the size of the Li+-bonded systems.
