| Outline of Final Research Achievements |
This project aimed at the development of novel valence tautomeric (VT) complexes which can form a meso-sized molecular assembly. We synthesized two new VT complexes, [Co(3,6-DTBQ)2(nEGEspy)2](ConEGEspy, n = 2 or 4), which have been structurally and spectroscopically characterized. Interestingly, both complexes are soluble not only in non-polar solvent such as toluene but also in polar solvents such as acetone and MeCN. This is resulted from the nature of EG chain with amphiphilic properties. The two complexes unexpectedly showed VT transformation coupled with a solid-to-melt phase transition in wide temperature range. These behaviors are highly contrastive with those of the previously reported alkyl-chain functionalized VT complexes. Thus we have succeeded in making new VT complexes which can a potential to form a meso-sized assemblies with bistable functionality.
