“…Gonsalves et al [38] used a convenient method for the interfacial polycondensation of 1,1 -bis(p-aminoethyl)ferrocene 11 with a variety of diisocyanates, leading to ferrocene-containing polyurea 12 in the presence of triethylamine as a proton acceptor as represented in Fig. 9.…”

The inclusion of organometallic units into polymeric structures has attracted much attention in different fields according to the nature and behaviour of the inserted metal. Moreover, the discovery of organometallic polymers and their structural characterization initiated an explosive rebirth of organometallic chemistry. Organometallic moieties are in or pendent to the polymer backbone and examine some of the uses of the emergent metallocene polymers, and new uses are still being found for these remarkable organometallic moieties. This review gives a simple introduction to variable organometallic molecules and their characteristics. This review will focus on the syntheses and characterization of organometallic polymers, including ferrocene-and phosphorus-containing polymers. A general overview on ferrocene polymers with a special attention to ferrocene-containing liquid crystalline polymers (including a ferrocene moiety in the main chain, side-chain or dendrimers) and fullerene-ferrocene liquid crystalline polymers is presented. In addition, more details for synthesis and properties of phosphorus-containing polymers are illustrated.

“…Amines 6 and 7 were obtained from 3 mmol of thiaacids 4, 1.22 g (4.5 mmol) of HgCl 2 , and 0.24 g (4.5 mmol) of NH 4 Cl in aqueous ammonia at 0 -5°C in a similar way as described above (Tables I and II). Resinous amines 10 and 11 were prepared starting from 3 mmol of dithiaacids 8 and 9, 2.44 g (9 mmol) of HgCl 2 , and 0.48 g (9 mmol) of NH 4 Cl in ammonia (Tables I and II).…”

Polyurethane polymers are a wide class of materials, ranging from surface coatings and adhesives to flexible or rigid foams. However, polyurethanes in general are very flammable and produce heavy smoke when burning. As a result of their flammability, there is a great interest in the development of materials with improved fire retardance. In this study a series of new ferrocene urethane block copolymers based on diphenylmethane-4,4Ј-diisocyanate were synthesized and their fire retardant behavior studied using thermogravimetric analysis (TGA), differential scanning calorimetry, cone calorimetry, and the oxygen index. Ferrocene-modified block copolyurethanes showed a 40 -80% reduction in peak heat release rate compared to an unmodified sample. In addition, the TGA results showed that ferrocene-modified polymers have high thermal stability and ferrocene enhances char formation in air and helium. The synergistic effect of silicone and phosphorus with ferrocene was also discussed. The solution electrochemical behavior of ferrocene-containing polymers was studied using cyclic voltammetry. These polymers showed a reversible wave at E°Ϸ 0.771-0.852 V and the electron transfer was diffusion controlled.
