The first Observation of high mass distribution of Polyrotaxane using MALDI-TOFMS and a high mass detector
Polyrotaxane (PR) is consisted with a linear polymer and slidable cyclic molecules, which are threaded on the polymer. Polyrotaxane gel is interlocked at ring components so that the polymer has a relative motion between the sliding rings along the main chain. Unique physical properties attributable to the relative motion of PR are greatly expected as a new industrial material. Whereas some successful studies of PR at low mass region have been reported with high resolving power of MS, an analysis of PR at high mass region is still difficult. We will report the first observation of PR at more than m/z 100,000 using MALDI-TOFMS equipped with a high mass detector, and discuss a structure of the polymer.
