Synthesis of Triptycene-Based Molecular Rotors for Langmuir-Blodgett Monolayers

Popis výsledku v původním jazyce

We describe syntheses of six triptycene-containing molecular rotors with several single-crystal X-ray diffraction analyses. These rod-shaped molecules carrying an axial rotator are designed to interleave on an aqueous surface into Langmuir-Blodgett (LB)monolayers containing a two-dimensional trigonal array of dipoles rotatable about an axis normal to the surface. Monolayer formation was verified with the simplest of the rotor structures. On an aqueous subphase containing divalent (c)ations (Mg2+, Ca2+,Zn2+, Sr2+, or Cd2+), the LB isotherm yielded an area of 53 +/- 3 angstrom(2)/molecule (monolayer of type A), compatible with the anticipated triangular packing of axes normal to the surface. On pure water, the area is 30 +/- 3 angstrom(2)/molecule, andit is proposed that in this monolayer (type B), the molecular axes are tilted by 40-45 degrees to a structure similar to those observed in single crystals of related triptycenes. After transfer to a gold surface, ellipsometry and PM IRRA
