Substrate-Binding Behavior of Octopus Azaparacyclophane, APC (C2Lys2C] 4)4... 

The microscopic environment for the substrate-binding site was evaluated from the fluorescence maximum of a selected probe. For guests such as PNA and ANS, whose molecular shapes are similar to each other, capped-APC provides a microenvironment nearly identical in polarity with those provided by THF and the octopus azaparacyclophane [APC(C2Lys2Ci4)4l Et(30) = 37 (see Figure 2). However, capped-APC provides a microenvironment with higher polarity for more slender molecules such as TNS E p(30)... 

Dowd et al. found that no rearranged product was obtained for the Bi2 derivative Co—CH2CH(C02H)CH(C02-)(NH3+) under thermal or photochemical decomposition. However, Murakami et al. observed substantial rearrangement in the organic products with the same and several related species when photolysis is done while the complex is bound to an anionic surfactant (octopus azaparacyclophane). They proposed that the surfactant is acting in a way analogous to the enzyme...
