An important aspect of this enhancement strategy is its compatibility with current fabrication techniques, in particular polymer processing technology. The technique of micro-injection moulding was employed to produce polystyrene chips with an integrated array of cone structures intended for use in an aqueous environment.

The conformational isomers of a cahxarene with four phenol residues are shown in Fig. 2.17. The isomers vary in terms of the orientations of their phenol groups (a) has a cone structure with all of the phenols pointing to the same direction (b) has a partial cone structure with one phenol pointing in a different direction to the others (c) has a 1,3-alternate structure with neighboring phenols pointing in opposite directions. These isomeric hosts have different selectivities for metal ion inclusion in the upper cavity and the lower cavity. Of course, changing the number of phenol residues alters the guest size appropriate for effective inclusion. 

On the basis of chemical properties and physicochemical inves.tigations dibenzene chromium is considered to have the same spatial distribution of bonds as ferrocene. X-ray studies have shown that the molecule is centrosymmetric, and that all the C-C and Cr-C distances are practically equal. One may therefore decide with certainty on the double cone structure (see Fig. 9). As already mentioned, it may be concluded that the metal-carbon bonds have an approximately octahedral arrangement and that the benzene rings have threefold symmetry.

Figure 6.11b shows cone structures formed at a temperature higher than 1300°C and total pressures at 30 Torr, which corresponds to region A in Figure 6.10. In this case, large primary cones are composed of secondary cones.

The relative energies shown in Table 4.3 are in agreement with experimental data that show the cone form as the most stable conformer. Why is this Overlaying an electron density map, calculated from the initial geometry using ab initio methods, on a cone structure shows that the lower rim phenolic groups...
