Résumé : The antrip monomer, in which a central triptycene core is extended to bear three anthraceno blades, is a versatile unit for the construction of two-dimensional polymers. The parent hydrocarbon antrip polymerizes in the crystalline state to afford a two-dimensional polymer, poly(antrip), whose structure was inferred from spectroscopic measurements. The dodecakisfluoro derivative, fantrip, was polymerized in the crystalline state to give poly(fantrip), whose structure could be determined by high-resolution single-crystal X-ray diffraction analysis. Both poly(antrip) and poly(fantrip) could be exfoliated into single sheets. Amphiphilic derivatives of antrip were organized and polymerized at the air/water interface to give large (cm2) single sheets that were characterized by scanning-tunneling microscopy, optical microscopy, electron microscopy, absorbance spectroscopy, and other methods.
