Mp. Byrn et al., PORPHYRIN SPONGES - CONSERVATION OF HOST STRUCTURE IN OVER 200 PORPHYRIN-BASED LATTICE CLATHRATES, Journal of the American Chemical Society, 115(21), 1993, pp. 9480-9497
Analysis of the molecular packing in over 200 tetraarylporphyrin-based
lattice clathrates reveals a strong conservation of host structure. I
n most cases, formation of porphyrin-based clathrates can be viewed as
arising from intercalation of guest molecules into pure host material
s. Several modes of intercalation are detected, and characteristic of
intercalate structures, staging is observed. Intercalate formation acc
ounts for the relative insensitivity of the host structure to the natu
re and size of the guest species. The structural conservation observed
in this large class of materials facilitates rational modification of
the host lattice. Crystallographic data are provided for 75 new porph
yrin-based clathrates.
