To facilitate the generation of a relatively large number of
beaded materials, a scaled-down suspension polymerisation
procedure (20 ml reaction volume), utilising a Carousel™
reaction station, was used to generate a series of quantum dotcontaining
polymer beads (Table 1).12§ For each of the polymer
samples described in Table 1, simple visual inspection indicated
that quantum dots had indeed been incorporated successfully.
However, in the case of beads produced using ligand 5 the
extent of quantum dot incorporation, as evidenced by microanalysis,
was very low (Table 1). Thus all subsequent
investigations utilised beads constructed using ligand 2. Each
sample was further analysed by i) fluorescent emission
fingerprinting (Fig. 1), ii) photoluminescence spectroscopy
(Fig. 2) and iii) elemental microanalysis after extended periods
of Soxhlet extraction (Table 1).
