Optical Second-Harmonic Generation of Tetrazole Derivatives

Abstract

Second-harmonic generation (SHG) was investigated for 48 tetrazole compounds. Nine tetrazole compounds were found to generate second harmonic light upon irradiation with Nd:YAG laser light and to have an absorption edge of short wavelength below 350 nm.

Synthesis, photophysical and nonlinear optical properties of push–pull tetrazoles

“…For instance, photophysical properties of compounds containing a tetrazole scaffold have been reported. [26][27][28] In addition, several coordination polymers involving tetrazole as a ligand have shown to display NLO properties [29][30][31][32] and a few substituted tetrazoles exhibit second harmonic generation (SHG), 33 however, to the best of our knowledge no NLO properties have been reported on tetrazole based push-pull systems. This may be because tetrazoles are typically regarded as conjugation disruptors due to the presence of a tertiary amine center that is expected to interrupt ICT from donor to the acceptor.…”
