Functional Polymers: Polymacrocycles

Functional Polymers: Polymacrocycles

Takashi Kaneko,* Takahiro Horie, Shinji Matsumoto, Masahiro Teraguchi, and Toshiki Aoki

T. Kaneko and coworkers synthesized a series of novel phenylacetylene monomers with a built-in macrocycle consisting of phenyleneethynylene repeating units. They successfully polymerized these monomers with a rhodium catalyst, [Rh(nbd)Cl]2, to give the corresponding polymacrocycles as yellow-red powders, which were soluble in common organic solvents, such as toluene, chloroform and tetrahydrofuran. In spite of their steric bulkiness a high degree of polymerization of about 500 could be reached. The polymacrocycles are expected to be suitable for providing materials with unique functions, such as tubular channels, guest-host complexes and porous organic solids.
