A combinatorial chemistry approach has been used to synthesize an array of Schiff bases, five of which, namely N-[(E,2E)-3-(4-methoxyphenyl)-2-propenylidene]-3-nitroaniline, C16H14N2O3, (1a), N-[(E,2E)-3-(4-methoxyphenyl)-2-propenylidene]-4-nitroaniline, C16H14N2O3, (2a), N-{(E,2E)-3-[4-(dimethylamino)phenyl]-2-propenylidene}-3-nitroaniline, C17H17N3O2, (1b), N-{(E,2E)-3-[4-(dimethylamino)phenyl]-2-propenylidene}-4-nitroaniline, C17H17N3O2, (2b), and N-{(E,2E)-3-[4-(dimethylamino)phenyl]-2-propenylidene}-2-methyl-4-nitroaniline, C18H19N3O2, (3b), have been structurally characterized. A stack structure is observed for (1a) and (1b) in the crystal phase. Experimental and calculated molecular structures are discussed for these compounds which belong to a chemical class having potential applications as non-linear optical materials.
