摘要
The synthesis, conformation, and monolayer assembly structure of a pentiptycene-derived α,ω-alkanedithiol (1) are reported. The results of MM2 modeling, the scanning tunneling microscopy (STM), and the surface plasmon resonance (SPR) suggest that 1 favors a folded conformation, corresponding to a looped monolayer assembly structure, on the Pt(111)and Au(111) surfaces. Nonetheless, the conformation of 1 in the crystals might be an extended form according to the crystal structure of an analogous compound 4. The relative interchain interactions and packing densities can account for the choice between a folded and an extended conformation for 1 in the condensed phases.
