초록/요약
Macrocycles were synthesized from monomers which are already conformationally pre-oriented for the coupling reaction to form macrocycles in high yield. We designed monomers that have two phenyl acetylene units within a 5,5-dibenzyl Meldrum’s acid unit which has a specific and rigid three-dimensional arrangement the two phenyl rings surrounding the Meldrum’s acid unit in both sides with high rigidity. Triple bond contributes to the rigidity of pre-oriented structure of the monomer and additional unique photophysical and electrical properties of the conjugated macrocycle. High rigidity of monomers improved the efficiency of cyclization to form macrocycles. The solubility of macrocycles was enhanced by introducing alkyl branches to macrocycles. Synthesis of macrocycles was confirmed by various analyzing methods.
