Adsorption separated double-molecular

Fig. 4.4 Pore-filling models for protein adsorption in a mesopore channel (a) separated single-molecularadsorption (b) separated double-molecular adsorption (c) separated triple-molecular adsorption (d) interdigitated triple-molecular adsorption where adjacent layers are interdigitated by 1/4 of the protein diameter through changing the relative orientation.

Figure 1.3 Molecular models showing the two enantiomers resulting from the loss of mirror plane symmet7 on adsorption with the molecular plane parallel to the substrate. The separation of enantiomers observed by STM is identified by the relative displacement of adjacent monomers within the double chain. (Reprinted with permission from Ref. [6].

Norbornadiene. Hamers and co-workers first studied the adsorption of norbornadiene (bicyclo[2.2.l]hepta-2,5-diene) [43] on Si(100) this molecule and a sample STM image are shown in Fig. 6 along with a functionally modified norbornadiene analogue [50] containing a silyl molecular rotor, which we have also investigated. Norbornadiene was in fact the first hydrocarbon containing multiple C=C bonds to be studied in this fashion. Its two double bonds are separated by 2.4 A and are chemically independent moieties, and hence this molecule could react twice with silicon via a double...
