| Research Abstract |
For the purpose of development of molecular integration method of sophisticated molecular elements on common polymers, we investigated the development of interlocked cross-linking method by using an ambident agent and the evaluation of characteristic properties of the resulting cross-linked polymer. As a result, we developed ambident agents possessing both stable nitrile N-oxide and electrophilic site and demonstrated the usefulness of the ambident agent as a chemical ligation tool. In addition, we achieved the synthesis of polymeric stable nitrile N-oxide. We also investigated the synthetic method of supramolecular polymers with rotaxane connecting points. Through considerable efforts, we developed a chemical recycle system exploiting a size-complementary[ 3] rotaxane element. In addition, we constructed a new synthetic method of various supramolecular architectures with rotaxane connecting points. Moreover, we found an unprecedented[ 3] rotaxane-cross-linker as a ligation tool between common polymer and interlocked cross-linking point. The relationships between nano-scale dynamic behaviors of the elements and macroscopic phenomena of the resulting materials were also investigated in detail.
