When the metalloporphyrin bears a donor group on its periphery, it can behave as a self-complementary ditopic unit capable of metal-ligand induced dimerization. Many systems have been synthesized using different metals, ligands, and spacers. The length and geometry of the spacer groups determine the stoichiometry of the assembly process. 

Fig. 7 Linear ID infinite chains formed on self-assembly of bidentate and self-complementary modules where donor and acceptor sites axes are parallel and coaxial (A), of bidentate donor and acceptor modules where donor and acceptor sites axes are parallel and coaxial (B), or are parallel and translated from each other in the XB donor (C) or acceptor (D) module, respectively...

Extensive reviews of Diels-Alder reactions and hetero-Diels-Alder reactions in aqueous media have been presented. " " " " Micelles in the presence of catalytically active transition-metal ions catalyse the Diels-Alder reaction between 3-(/ -substituted phenyl)-l-(2-pyridyl)prop-2-en-l-ones with cyclopentadiene by a factor of 1.8 x 10 compared with the uncatalysed reaction in MeCN. " Diels-Alder reactions have been shown to be accelerated by encapsulation of both reactants by pseudospherical capsules assembled from self-complementary molecules (103). " ... 

The mixed sites species TPU would represent a self-complementary component capable of homo-self-assembly into a (TPU) supramolecular entity. 

Homo-assembly of derivatives of the self-complementary recognition group 168 can only yield a linear ribbon or tape structure 179. This is indeed the case, as shown... 

Fig. 47. X-Ray structure of the hydrogen-bonded, ribbon-like species formed by self-assembly of the self-complementary component 168. In the schematic representation (right) the two DMF molecules contained in each cavity between the octyl chains are omitted [9.122].

Fig. 23 Schematic illustration of the formation of a nanotube from a single sequence composed of four self-complementary segments (shown in different colors in (a)) the strand forms DX tiles (b) which then assemble into folded sheets (c, d). Adapted from [105]...

Figure 7-25. Hydrogen bonding between carbonyl groups and amino N-H groups is a useful structural feature for the assembly of supramolecules. Part of the hydrogen bonding network present in the solid state lattice of the zwitterionic compound anthranilic acid is shown in a). The self-complementary hydrogen bonding possible with an amide is shown in b).

Self-assembling systems do not involve hosts and guests but rather self-complementary molecules or...
