Self-assembly with hydrogen bonding polymers

With the exception of l,6-naphthyridin-8-ols, nuclear hdyroxy-1,6-naphthyridines would be expected to exist as the corresponding naphthyridinones. This has been confirmed by infrared,1035 ultraviolet,1026 and nuclear magnetic resonance spectral means.639 Other physicochemical studies of these oxy-1,6-naphthyridines include IR stretching frequencies1019 and ionization constants1040 of 1,6-naphthyr-idin-8-ols the mass spectra of 1,6-naphthyridinones the effect of solvents on the UV spectrum of an 8-hydroxy-1,6-naphthyridine derivative 773 and X-ray analysis of the dilactam, 4-hexyl-3,4,4a,5-tetrahydro-l,6-naphthyridine-2,7(l//,6Z/)-dione (1), in connection with its crystallization as self-assembled hydrogen-bonded polymers.549...

Yu et. al, found that molecules containing two 2,6-diacetamido-4-pyridone groups and a nonlinear optical chromophore will self-assemble with diimides or bis(uracil) structures, to yield polymer-like hydrogen-bonded assemblies.
