Abstract

Two C2-symmetric meso-alkynylporphyrins, namely 5,15-bis-[(4-butyl-2,3,5,6- tetra-fluoro-phen-yl)ethyn-yl]-10,20-dipropyl-porphyrin, C50H 42F8N4, (I), and 5,15-bis-[(4-butyl-phen-yl) ethyn-yl]-10,20-dipropyl-porphyrin, C50H50N4, (II), show remarkable π-π stacking that forms columns of porphyrin centers. The tetra-fluoro-phenyl-ene moieties in (I) show inter-molecular inter-actions with each other through the F atoms, forming one-dimensional ribbons. No significant π-π inter-actions are observed in the plane of the phenyl-ene and tetra-fluoro-phenyl-ene moieties in either (I) or (II). The molecules of both compounds lie about inversion centers.
