Main-Chain Polymetallocenes with Short Spacer Groups 

As described in Chapter 2, attempts to incorporate ferrocene into the side-chain structure of polymers have been very successful. In this case, a variety of high

Nevertheless, despite these breakthroughs, it is very apparent that the incorporation of metallocenes other than ferrocene into polymer structures has been developed to a much lesser extent, and for the 21st century, this still remains a substantial synthetic challenge. This is despite the fact that many other metallocenes are readily accessible, stable, and also exhibit interesting physical, redox, and catalytic properties [2, 4, 9]. The lower ease of derivatization of most other metallocenes compared to ferrocene and, in some cases (e.g. that of ruthenocene), the problem of relative expense, have clearly been important factors which have held back synthetic developments in this area. Nevertheless, it is anticipated that the development of main hain polymers based on other metallocenes is likely to be very fertile ground for future research. 

Excellent, critical reviews of the general field of main-chain metaDocene-based polymers were published as early as 1970 [10]. At this time, the authors were more than aware of the limitations in the characterization of the vast majority of
