Outline of Final Research Achievements |
Selective cycloaromatization (SCAT) of a racemic helical poly[3,5-bis(hydroxymethyl)-4-dodecyloxyphenylacetylene] by circularly polarized light (CPL) was investigated. The racemic helical polymer, which was synthesized by polymerization of achiral monomer under achiral conditions, has equal amounts of right- and left-handed sense helical main chains. SCAT using CPL proceeded in helix-sense-selective manner and gave a preferentially one-handed helical polymer (creation of chirality). In addition, using the chirality which was a trace amount created by CPL as chiral source, helix-sense-selective polymerization of another monomer was achieved (asymmetric amplification and asymmetric transfer).
