An easy and efficient solvent-free synthesis of 1-(azulen-1-yl)-2-aryl- and heteroarylethenes is described. The reaction was performed simply by melting solid mixtures of azulenic Schiff bases and arylacetic acids, the crude products being purified by column chromatography. Limitations of the method were established by study of a large range of aryl and heteroarylacetic acids and also by examination

Several novel, thermally stable azulene-containingdonor-acceptor molecules were synthesized and their second-ordernonlinear optical properties determined by the EFISH method. The βμ-values for these new compounds featuring azulene as the pi-electron donor were comparable with NLO compounds containing para-N,N-diethylaniline as the electron-donor.
