In the title compound, C24H15FN2O2, the dihedral angles between the central benzene ring and the oxazole rings are 10.7 (6) and 64.1 (5)°. The dihedral angles between the oxazole rings and their pendant rings are 2.0 (3) and 24.3 (2)°. The F atoms are disordered over two sites with occupancies of 0.627 (3) and 0.373 (3) in the phenylene–oxazolyl–phenyl and in oxazolyl–phenyl fragments, respectively. In the crystal structure, molecules are linked through a network of C—H⋯F and weak π–π stacking interactions.

“…Thus, the polycondensation of oxamide 138, 139) has furnished a polymer with condensed pyrazine cycles in the main chain. Poly(benzothiazole)s 144), poly(benzimidazole)s and their analogues [140][141][142][143][144], poly(pyromeUitimide)s 14s), poty(imidazopyrrolone)s [146][147][148][149], and poly(imidazopyrone)s150) have been obtained in the same type of reactions. These reactions are becoming important for making materials of specified structures by adequate processabilities due to the possibility of performing stepwise processes, i.e., by preparation of soluble prepolymers in the first stage with subsequent cyclization to PCSs.…”
