Chemists would like to invent molecules that assemble themselves into specific, we 11-organized arrays. Recently there have been some exciting successes. Our inset is a molecular view of a self-assembled molecular wreath. This organized sfructure forms when four molecular chains weave themselves together in the presence of 12 copper cations. Self-assembling molecular systems could lead to new materials with useful properties. They may also shed light on how life originated. 

Polycyclic compounds 700-702 are examples of symmetrical molecules able to self-assemble molecular hosts capable to surround completely their guests. 

Recently, it has been found that the outcome of some cycloadditions can be altered remarkably when performed inside the cavity of cyclodextrins (288), self-assembled molecular capsules (289), or coordination cages (290). This fact intrigued us greatly and stimulated our interest in the Diels-Alder reactivity of the calixarene-like [M2(L19)(L )]+ complexes bearing unsaturated carboxylate coligands L (215).

It should be stressed that the most widely accepted models of the origin and evolution of life are based on the concept of self-assembling molecular systems. The models rooted in information theory involve [17] ... 

Porphyrin-based self-assembled molecular squares 389 can form mesoporous thin films in which the edge of a square, thus the size of the cavity, can be adjusted by appropriate choice of substituents [8]. Fibers that form coil-coiled aggregates with distinct, tunable helicity are built from crown ethers bearing porphyrins 390 [9]. In addition to the porphyrin applications discussed in Sections 6.3.2.2 and 6.4, dendrimer metalloporphyrins 391 to be applied in catalysis [10] and the water-soluble dendritic iron porphyrin 319 modelling globular heme proteins [11] can be mentioned.

In this chapter we will review some of the landmark publications in self-assembled molecular electronics. We will also review newer work from our own lab as well as others in the field. 

RECENT WORK IN SELF-ASSEMBLED MOLECULAR ELECTRONICS... 

The use of self-assembly techniques in molecular electronics has proven to be useful, as shown by the many publications cited. We expect the field to continue to develop and mature as researchers fine-tune their procedures and new methods are developed. Processes refined for the molecular electronics field will find applications in other nanotechnology areas the reverse will also be true. Thus, as it will be beneficial for those in the solid-state microelectronics field to look toward molecular electronics for solutions to their problems, it will also be beneficial for those in the field of self-assembled molecular electronics to look outside that narrow range of technology for potential solutions to their problems. The coming years will surely see many exciting developments.
