摘要：
Hybrids possessing both oligomeric ethylene oxide chains and Ti-O-P networks were prepared from TiCl4 and organodiphosphonic acid [(HO)(2)OP(C2H4O)(3)C2H4PO(OH)(2)] via a nonhydrolytic sol gel process and subsequently treated with a LiClO4 solution. The P/Ti ratio was fixed at 2 and the ethylene oxide unit/Li+ ratio was changed from 5 to 20. Li+ ions are likely to be solvated by ether oxygen atoms. Li+ ion transport in the hybrids with ionic conductivity values in the 10(-5) S cm(-1) range was observed at ambient temperatures.
