| Outline of Final Research Achievements |
Oligo(2-phenylthiazole)s with alpha-beta-connectivity were synthesized and the conformational preferences were studied by means of NMR and X-ray crystallography. The oligothiazoles with head-to-tail connectivity were found to preferentially form helical structures. Interestingly, the hexamer showed chiral crystallizaion, where the achiral hexamer crystallized into chiral crystals with an identical helical handedness. The oligomers with inversion connectivity were capable of photochromic reaction, showing the dynamic modulation of helical structure.
