Research output: Contribution to conferencePaper


Porphyrin derivatives UP1 was synthesized by condensation with N-pentyl orotic acid and bis(diaminophenyl) porphyrin derivative. Meso-UP was synthesized, and then atrop isomere (αα, αβ) were separated stably by column chromatography. The mixed benzene solution with Glu-M and UP1 was gelated at room temperature. The benzene casted film of UP1 and Glu-M showed anisotropy, which means well-defined porphyrin structure. When Glu-M was added to suspended Meso-UPαα CHCl3 solution, the clear solution was obtained, which means formation of hydrogen bonded assembly.
