N2 - The synthesis is reported of well-defined and narrow molecular weight distribution macrocyclic poly(2-vinylnaphthalene) (P2VN) and poly(9,9-dimethyl-2-vinylfluorene) (PDMVF) containing a single 1,4-benzylidene or 9,10-anthracenylidene unit. The synthesis involves the potassium naphthalide (K-Naph) initiated polymerization of 2VN or DMVF in THF at -78°C followed by end-to-end coupling of the resulting P2VN dianions under high dilution conditions (10-6-10-4 M) with 1,4-bis(bromomethyl)benzene (DBX) or 9,10-bis(chloromethyl)anthracene (BCMA). The molecular characterization was carried out by size exclusion chromatography (SEC), NMR and MALDI-TOF.
