Research Abstract

We found that anthracene part in the designed organogelator underwent photodimerization by UV-light to give head-to-head selectivity in the dimer product in the gel phase. This observation implies that molecules nicely align for the selective reaction in the gel phase. On the other hand, naphthalenediimide-based gelator shows thixotropy in highly diluted condition. Therefore, TEM observation revealed the thixotropic process that gelator molecules disassemble by shaking and assemble with time.
