The synthesis and study of dendrimers is a relatively new branch of macro-molecular chemistry. It began in 1985 with the publication of two landmark papers (D.A. Tomalia, H. Baker, J. Dewald, J.M. Hall, G. Kallos, R. Martin and J. Ryder, Polym. J., 1985,17,117-132 and G.R. Newkome, Z. Yao, G.R. Baker and V.K. Gupta, J. Org. Chem., 1985, 50, 2003-2004), and has grown to become a very vibrant research field. The word dendrimer comes from the Greek word dendra, meaning tree, and was applied to these compounds by Tomalia et al. in their very first paper. Newkome s team, by contrast, called their molecules arborols from the Latin word arbor, which also means a tree. The term cascade molecule has also been used, but the word dendrimer is the one that is used most widely throughout the literature, and is also used in the present chapter.

In 1992, R.M. Laine (University of Michigan, Ann Arbor) announced the development of a process that transforms sand and other forms of silica into reactive silicates that can be used to synthesize unusual silicon-based chemicals, polymers, glasses, and ceramics. The Lame procedure produces pentacoordinate silicates directly from low-cost raw materials—silicon dioxide,ethylene glycol, and an alkali base. The mixture is approximately a 60 1 ratio of silica gel, fused silica (or sand) to metal hydroxide and ethylene...

For understanding the complicated function of nucleic acids, it is desirable to gain information about the electrochemical properties of these polymers or their components. The first study about the polarography of purine derivatives was published by Heath [77] in 1946. Most new ideas for the electrochemical study of this attractive problem [78-83] were presented by Elving, (University of Michigan, Ann Arbor) and Palecek (Institute of Biophysics, Czechoslovak Academy of Sciences, Brno).

Dendrimers (sometimes called arbor, cascade, or starburst molecules) share some characteristics with polymers but also manifest critical differences. Whereas linear polymers like polystyrene are polydisperse (have a range of molecular weights and character), dendrimers, synthesized in a stepwise manner, are monodisperse (have uniform molecular mass). Unlike polymers, their growth becomes at some stage self-limiting as the molecule folds into itself. Unlike linear polymers, which present countless rapidly interconverting shapes, dendrimers are nearly spherical in shape with diameters typically between 2 and 10 nm.

G.S.Y. Yeh (University of Michigan, Ann Arbor, Michigan) Listening to you reminded me of some of the work we ve done on crystalline polymers. There appeared to be some transition above the melting point. I know how difficult it is to do some of these experiments, but you have concentrated mostly on two molecular weights, is that correct ... 

R.E. Robertson (University of Michigan, Ann Arbor, Michigan) You still could state the principal fact in the matter. Dr. Yeh, which is that the mean end-to-end distance or radius of gyration for the polymer when it s crystallized is about the same as when it s in solution.
