Description

We report the measurement of the degenerate fourth-wave mixing (DFWM) of adininium dinitrate in aqueuse aqueous solutions at λ= 532 nm in ps regime with different numbers of π-conjugated bonds. From these measurements, we evaluated the values of the second order hyperpolarizabilities γ, which are about 103 larger than the γ value of CS2. The influence of π-conjugated bonds on the third-order susceptibilities and appropriate figures of merits is discussed. The more important seems to be the possibility of a simultaneous increase of the third-order susceptibilities, together with the decrease of the absorption coefficients that open a possibility of their use as promising materials for laser wavelengths mixing. In the

asymmetric unit of the title compound, C5H7N5 2+, 2NO3, the adenine base is diprotonated and cocrystallizes with two nitrate anions. The structure is a layered one, and in each layer all H atoms …
