Linear and Third-Order Nonlinear Optical Properties of Triazobenzene-1,3,5-triazinane-2,4,6-trione (Isocyanurate) Derivatives

Pokladek, Z; Dudek, M; Mongin, O; Metivier, R; Mlynarz, P; Samoc, M; Matczyszyn, K; Paul, F, ChemPlusChem, 2017, 82, 1372-1383.

The synthesis of three new isocyanurate derivatives 2‐X (X=NO2, H, NMe2) with azobenzene arms terminated by various X substituents is reported, and their linear and nonlinear absorption properties are studied. It is shown that mixtures that contain increased contents of cis‐azo isomers can be reversibly generated upon photoirradiation at specific wavelengths from the most stable all‐trans isomers with X=NO2 and H. In addition, we show that 2‐X derivatives are two‐photon absorbers with cross‐section maxima around 120 GM for 2‐NO2, thus indicating that trans‐to‐cis isomerization might be achievable by two‐photon excitation, whereas the photoinduced structural changes should have only a modest influence on these nonlinear absorption properties.
