We have recently proposed new crystal engineering utilizing so-called
fluorophilic nature of the perfluoro compounds. Our idea is based
on the fluorine-containing hybrid compounds, RF-X-RH, consisting of
a junction group (X), perfluoroalkyl (RF) and hydrocarbon (RH) moieties.
Systematic investigation of the crystal structures of such hybrid
compounds revealed the existence of five motifs (Type I to V) in their
crystal packings and their relationships with the topology of the
molecules. Based on the topology-packing relationship, we designed
polymerizable diacetylene derivatives with the Type II packing motif
and actually obtained black polymer crystals with metallic luster
by solid-state polymerization under uv irradiations.
