Vertically Oriented Propylene Carbonate Molecules and Tetraethyl Ammonium Ions in Carbon Slit Pores
We
report the vertical alignment of propylene carbonate (PC) molecules
interacting with Et<sub>4</sub>N<sup>+</sup> and BF<sub>4</sub><sup>ā</sup> which are confined in extremely narrow slit pores
(<i>w</i> ā¼ 0.7 nm) of carbide-derived carbon and
pitch-based activated carbon fiber. On the basis of X-ray diffraction
(XRD), electron radial distribution function analysis reveals that
the nearest PCāPC distance is 0.05ā0.06 nm shorter than
that in the bulk solution, indicating dense packing of PC molecules
in the pores. This confinement effect results from the vertically
aligned PC molecules, which are indicated by the reverse Monte Carlo
analysis. The ensemble structure of PC molecules in the subnanometer
carbon pores will provide better understanding the supercapacitor
function
