Soluble polydiacetylenes (CR-C=C-CR'=)n [R=R'=(CH2)9O2CCH2Ph (2a); R=(CH2)9CH3, R'= (CH2)8CO2CH2Ph (2b)] have been synthesized and reacted with Co2(CO)8 to introduce varying proportions of Co2(CO)6 groups, attached as Co2C2 tetrahedrane units, at the alkyne bonds of the conjugated ene-yne backbone. These metallated polymers have been characterised by analytical data and by IR, 13C{1H} NMR and UV-VIS spectroscopy. Reactions between polydiacetylenes 2a or 2b and [M2(CO)4(?5-C5H 5)2] (M=Mo, W) are also reported. The presence of fast optical non-linearities in these soluble polymeric materials was confirmed by fluorescence lifetime measurements and optical characterisation of the imaginary part of ?(3). These studies were conducted on a picosecond timescale to allow electronic contributions to be resolved, and the related Im ?(3) values tabulated against metal content and solution concentration.
