Abstract

Nonlinear optical materials are getting attention in the field of optical data storage, telecommunication, second harmonic generation (SHG) and optical signal processing, etc. In the present work, Ethyl 3-nitronaphtho[2,1-b]furan-2-carboxylate 2 has been synthesized from ethyl naphtho[2,1-b]furan-2carboxylate (1). This product on reaction with hydrazine hydrate formed 3-nitronaphtho[2,1-b]furan-2carbohydrazide (3). By treatment of hydrazide 3 with different aromatic aldehydes various Schiff’s bases,i.e., 3-nitro-N1 (aryl-methylene)-substituted-naphtho[2,1-b]furan-2-carbohydrazides 4(a-g) were obtained .
