Linear and nonlinear properties of novel materials based on DNA containing [2.2]paracyclophane moiety

Abstract

In this study, the synthesis and the characterization of new deoxyribonucleic acid (DNA) based compounds containing [2.2]paracyclophane moiety are reported. The DNA molecule was functionalized with hexadecyltrimethylammonium chloride (CTMA), [2.2]paracyclophane-4-methoxy-5-formyl [A] and [2.2]paracyclophane-4-hydroxy-5-formyl [B], respectively. These compounds were used for obtaining good optical quality thin films by spin coating method. The absorption and emission spectra of studied solutions and thin films showed that the new obtained materials are of good optical properties. The third-order nonlinear optical (NLO) properties of thin films were characterized by the optical third-harmonic generation technique at 1064.2 nm fundamental wavelength.
