Abstract

Aperiodic alkane/urea inclusion compounds (UIC) are prototype composites which exhibit complex sequences of phases that can clearly be described in the (3+d) dimension crystallographic superspace. By simply changing the length of the guest alkane molecules (C n H2n+2) which pile up in the channels of the host urea honeycomb-like framework, it is, for instance, possible to have phase-ordering phase transition from 3 to (3+1) dimension in the case of n-heptane/urea (n=7), or as in the case of n-hexadecane/urea (n=16) or n-nonadecane/urea (n=19), a generalization to higher dimensions of the phase transitions found in modulated structures. Such results are successfully obtained with the help of high resolution diffraction methods.
