Shape-persistent phenyl ethynylene macrocycles with intraanular flexible oligooxylethylene chains were synthesized by intramolecular Glaser coupling reaction of half rings. The structures of target phenyl ethynylene macrocycles were identified by 1H NMR, 13C NMR, HRMS, UV and PL (photduminescence), The purity of the target macrocycles was determined by GPC. All the macrocycles are nomesogens as indicated by polarized optical microscopy (POM) and differential scanning calorimetry (DSC), the reason is analyzed as the streric hindrance of the intrannular flexible chains which led to the anordered aggregation of the macrocycles.

Key words: phenyl ethynylene macrocycle, synthesis, intrannular, oligooxylethylene chain
