A combinatorial chemistry approach to new materials for non-linear optics. I. Five schiff bases
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, C(16)H(14)N(2)O(3), (1a), N-[(E, 2E)-3-(4-methoxyphenyl)-2-propenylidene]-4-nitroaniline, C(16)H(14)N(2)O(3), (2a), N-(E, 2E)-3-[4-(dimethylamino)phenyl]-2-propenylidene-3-nitroaniline, C(17)H(17)N(3)O(2), (1b), N-(E, 2E)-3-[4-(dimethylamino)phenyl]-2-propenylidene-4-nitroaniline, C(17)H(17)N(3)O(2), (2b), and N-(E, 2E)-3-[4-(dimethylamino)phenyl]-2-propenylidene-2-methyl-4-nitroanil ine, C(18)H(19)N(3)O(2), (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.
