Synthesis and study of novel coumarin derivatives potentially utilizable as memory media

Molecules. 2009 Nov 25;14(12):4838-48. doi: 10.3390/molecules14124838.

Abstract

Novel coumarin derivatives, 2-oxo-2H-chromenecarbaldehyde hydrazones were prepared by reaction of substituted 2-oxo-2H-chromenecarbaldehydes with N-aminoimides in ethanol in the presence of 4-toluenesulfonic acid as catalyst. The photochromic and thermochromic properties of the prepared compounds were investigated.
