Abstract
The introduction of fluorescent moieties in the polymeric chain permits the preparation of luminescent materials with potential applications. In this report, a number of aromatic nanosized polyamides containing both pendant acetoxynaphthamide and acetoxybenzamide were synthesized and characterized. The nanosized polymers were obtained as well-separated spherical and/or ring-shaped forms based on the pendent structure and the average diameter was 130 nm. Structure-properties correlations based on changing either the diamine and/or the pendent group demonstrated interesting connections. The polymers exhibited two major thermal decompositions attributed to the breakage of the main amide chain and the residual diacid-containing pendant moieties, respectively. Noteworthy, no significant change in the absorption spectra was noticed on phenylene / pyridine unit interchange.
