Notes:
Fluorescence spectroscopy in highly dilute solutions has been used to study the emission from naphthyl groups attached to poly(methyl methacrylate) molecules prepared by (i) free-radical polymerization, giving an essentially random distribution of naphthyl groups along the chain, and (ii) anionic polymerization, producing polymers with naphthyl groups in terminal units only. The influence of molecular architecture on the fluorescence is discussed. In particular it is shown that it is possible to incorporate one single naphthyl group at one end of a polymer chain but that attempts to introduce a controlled greater number lead to a product with a distribution of naphthyl-group constents.
