Associative group

Summing up the results Depending on whether the corona of edges is treated as a configuration in two- or three-dimensional space or as a topological object, the admissible permutations form the "associated" groups Hj, respectively. 

IV. a permutation of the edge numbers is induced, and this permutation is in the associated group of each corona. 

Reading the deductions in reverse order, we conclude two planted trees are congruent to each other if and only if they have the same number of principal branches and the configurations of the principal branches are equivalent with respect to the associated subgroup. Depending on the associated groups A 4, H j, the associated subgroups are A3 H3, and respectively. These...

The use of monomers bearing more than two associating groups is a straightforward way to introduce a controlled amount of branches or crosshnks in a supramolecular polymer structure [6,58,121,123-127]. The improvement of the mechanical properties can be spectacular. For instance, trifunctional monomer 17 (Fig. 21) forms highly viscous solutions in chloroform, and is a viscoelastic material in the absence of solvent [124]. The reversibly cross-linked network displays a higher plateau modulus than a comparable covalently cross-linked model. This is explained by the fact that the reversibly cross-hnked network can reach the thermodynamically most stable conformation, whereas the covalent model, which has been cross-linked in solution and then dried, is kinetically trapped. 

Hydrogen bonding of associative groups is often characterized by a measurable shift of an absorption band. The measure of the intensity of these bands affords the equihbrium constant [90,107,185,199]. However, the use of FTIR spectroscopy is less versatile than NMR spectroscopy because solvent absorption often limits the dilution range accessible.
