Side-Chain Metal-Containing Polymers

For many applications, side-chain metal-containing polymers are sufficient. However, to access the most profound alterations in polymer properties that arise from the presence of metal atoms in a polymer structure, incorporation in the main chain is required. Potential advantages of including metals in the backbone of a polymer rather than the side-group structure include the following ... 

A connectivity of 1 is given for side chain metal-containing polymers as 1 in which the metal complex is connected via one bond to the main chain [11]. Additional examples for other connectivities are (Fig. 1-8) connectivity 2 in metal(yne)s 2 [12] connectivity 3 in arsenic(III) sulfide 3 connectivity 4 in a polymeric methyl rhenium oxide of the formula Ho.5[(CH3)o.92Re03] co 4 [13] or polymeric phthalocyanines 5 [14] connectivity 8 in lanthanide complexes of bis(tetradendate) Schiff base bridging ligands 6 [15].

Block co-polymers exhibit outstanding potential for a variety of applications as a result of their self-assembly into supramolecular structures (see Section 1.2.4). However, the exploration of organometallic multi-block materials was only begun in the early 1990s. Block co-polymers derived from the living anionic polymerization of vinylferrocene have been already briefly mentioned in Section 12.06.2.2.l.(i). In this section, side-chain metal-containing block co-polymers are surveyed. Examples of block co-polymers with metals in the main chain are discussed in Section 3.X. 

The living ROMP reactions of norbomene and norbomene derivatives have been used to make a variety of polymers possessing unusual properties. Copolymerization of selected fimctionalized norbomenes with norbomene has been used to synthesize star polymers and side-chain liquid crystal polymers. This chemistry has also resulted in the preparation of phase separated block copolymers that contain uniform sized metal or semiconductor nanoparticles. The... 

This chapter reviews research published on conjugated metal-containing polymers from late 1998 to mid-2005. It includes polymers where the metal is incorporated into the backbone or the side chain of a conjugated polymer. Kingsborough and Swager wrote an excellent review of the field up to late 1998, and we do not intend to repeat any of their efforts herein.11 However,... 

Polymers containing Hf(TV) in the main chain or side chains can be prepared by any of the known processes for synthesis of metal-containing polymers. An attractive approach is the polycondensation of dicyclo-pentadienyl derivatives of hafnium(IV) with diols or oxygen-free diacetylenic hgands. An alternative approach is polymerization of the Hf(TV) monomers with (meth)acrylate and fumarate groups, synthesized for the first time in this study. We investigated the thermolysis of the synthesized...
