“…3, after annealing at 85°C for 200 h, the EO coefficients can retain more than 85% of its initial r 33 value. This percentage is considerably higher than those of APC/10%DFTC-1 investigated previously, where only 75% of the initial r 33 value is kept after 200 h [23].…”

“…On the other hand, the main evidence of the decrease of the absorption band at 430 nm is the fact that this flattened and distorted spectral band drastically changes its shape (after poling) to a less pronounced band with a monotonically decreasing behavior (in both cases: Figures 6a, b) and Hence it is concluded that the mechanical stability of this polymer can be explained in terms of its inherent main-chain rigidity. Indeed, according to Huang and coworkers [32], the introduction of a biphenylene group may efficiently decrease intermolecular electrostatic interactions, stimulating the chromophore alignment.…”

Excellent quadratic non-linear optical (ONL-2) properties of the poly(2,5-bis(but-2-ynyloxy) benzoate, containing a polar diacetylene as a chromophore, were found. According with the Maker fringes method, oriented polymer films showing an order parameter of ∼0.23 can display outstanding and stable Second Harmonic Generation (SHG) effects under off-resonant conditions (SHG-532 nm). Also, the macroscopic non-linear optical (NLO)-coefficients were evaluated under the rod-like molecular approximation, obtaining: χzzz(2) and χzxx(2) in the order of 280 ± 10 and 100 ± 10 pm V−1, respectively. The mechanical and chemical properties, in addition to the large ONL-2 coefficients exhibited by this polymer, make it a promising organic material in the development of optoelectronic/photonic devices.

“…Organic NLO materials are currently attracting considerable attention because of their attractive advantages, which include low production cost, low dielectric constants, high photoelectric coefficients, ready processability, and ultrafast response . Therefore, the NLO response of the aforementioned organic electride Na@(TriPip222) was evaluated for the first time in this work.…”

Excess-electron compounds can be considered as novel candidates for nonlinear optical (NLO) materials because of their large static first hyperpolarizabilities (β ). A room-temperature-stable, excess-electron compound, that is, the organic electride Na@(TriPip222), was successfully synthesized by the Dye group (J. Am. Chem. Soc. 2005, 127, 12416). In this work, the β of this electride was first evaluated to be 1.13×10 au, which revealed its potential as a high-performance NLO material. In particular, the substituent effects of different substituents on the structure, electride character, and NLO response of this electride were systemically studied for the first time by density functional theory calculations. The results revealed that the β of Na@(TriPip222) could be further increased to 8.30×10 au by introducing a fluoro substituent, whereas its NLO response completely disappeared if one nitryl group was introduced because the nitro-group substitution deprived the material of its electride identity. Moreover, herein the dependence of the NLO properties on the number of substituents and their relative positions was also detected in multifluoro-substituted Na@(TriPip222) compounds.
