Functionality complementarity

Probing the effect of functional group modification was achieved by using the compounds 27-3437,51 > for the recrystallization experiments. These compounds are expected to show functional complementarity different to 26. Table 5 summarizes the results. Inclusion compounds with protic and aprotic guest species are formed of 28, 31, and 33, respectively. All the other potential hosts are ineffective. Hence it is demonstrated that the COPh groups of 33 are not suitable for coordinative...

The ring-shaped units can be linked according to a type of crystal engineering Assembly due to synergetically induced functional complementarity of distinct surface sites (see below). 

In the last process it can be considered that the reaction is facilitated by synergetieally indueed functional complementarity. Examination of the overall strueture forms reveals the presenee of a two-dimensional layer in which the cavities of the Giant-Wheel eluster staek up on eaeh other to form nanotubes that are filled with H2O moleeules and sodium eations, see Figure 50. 

The guanidinium ion acts analogously in the process of synthesis of L25 (Eq. 1.14) [59]. Steric and functional complementarity between the guanidinium ion, ligsons and ligand product predetermine the success of the synthesis of 27-membered macrocycles L24 and L25. 

Considering functional group complementarity, other commodity monomers may also be used. Thus for templates containing acid groups, basic functional monomers are preferably chosen. The 2- or 4-vinylpyridines (VPY) are particularly well-suited for the imprinting of carboxylic acid templates and provide selectivities of the same... 

The third problem is like the confusion caused in MT by maintaining the concept of the Ether. Most practitioners of QM think about microscopic systems in terms of the principles of QM probability distributions, superposition principle, uncertainty relations, complementarity principle, correspondence principle, wave function collapse. These principles are an approximate summary of what QM really is, and following them without checking whether the Schrddinger equation actually confirms them does lead to error. 

III. Experimental observation of Quantum Mechanics. Only this final section should address the rules that govern interpretations of experiments measuring properties of QM systems with macroscopic devices. This includes probability interpretation, uncertainty relations, complementarity and correspondence. Then experiments can be discussed to show how the wave functions manipulated in section I can be used to predict the probabilistic outcome of experiments. 

The condensation reactions described above are unique in yet another sense. The conversion of an amine, a basic residue, to a neutral imide occurs with the simultaneous creation of a carboxylic acid nearby. In one synthetic event, an amine acts as the template and is converted into a structure that is the complement of an amine in size, shape and functionality. In this manner the triacid 15 shows high selectivity toward the parent triamine in binding experiments. Complementarity in binding is self-evident. Cyclodextrins for example, provide a hydrophobic inner surface complementary to structures such as benzenes, adamantanes and ferrocenes having appropriate shapes and sizes 12) (cf. 1). Complementary functionality has been harder to arrange in macrocycles the lone pairs of the oxygens of crown ethers and the 7t-surfaces of the cyclo-phanes are relatively inert13). Catalytically useful functionality such as carboxylic acids and their derivatives are available for the first time within these new molecular clefts.
