Abstract
The syntheses of two new pyrene‐containing monomers—2‐(1‐pyrenyl)methyl‐2‐oxazoline (6) and methyl 2‐(1‐pyrenyl)acetamidopropenoate (12)—and their polymerization are described. Cationic isomerization polymerization of 6 with ethylene glycol ditosylate initiator gave poly[N‐(1‐pyrenyl)acetyl ethylenimine] (7) and free‐radical polymerization of 12 with AIBN initiator gave poly[methyl 2‐(1‐pyrenyl)acetamidopropenoate] (15). The monomer model compounds of the two polymers, namely, N,N‐diethyl(1‐pyrenyl)acetamide (9) and methyl 2‐methyl‐2‐(1‐pyrenyl)acetamidopropanoate (14), were also synthesized. The polymers were characterized by elemental analysis, IR spectroscopy, and a comparison of their ^1^H‐NMR spectra with those of the respective monomer model compounds.
