Stable SHG from in situ grown oriented nanocrystals of [(E)-N,N-dimethylamino-N′-methylstilbazolium][p-toluenesulfonate] in a PMMA film

Cu(I) hybrid inorganic–organic materials with intriguing stimuli responsive and optoelectronic properties

“…To reach this goal various strategies have been proposed such as stepwise construction of multilayers, LangmuirBlodgett films, self-assembly in layered crystalline structures or in films, chirality to induce acentric crystalline structures, ordered inclusion in 1D or 2D host structures and electrical poling the latter being an intensively investigated field [176,177]. In the poling process, the initial random dispersion of the polar chromophores is broken to generate asymmetry by aligning their dipole 1,3,5-tris(diallylaminomethyl)-2,4,6-trimethylbenzene (TTB).…”

Growth, structural, optical and thermal properties of potential THz material: N, N-dimethylamino-N′-methylstilbazolium 4-styrenesulphonate

“…The optical absorption spectrum of DSSS dissolved in methanol was also recorded. It is well known that when the DAST and its derivatives are dissolved in methanol, it leads to dissociated state generating free cations and anions [17]. Thus, the absorption behavior of DSSS in the visible region is not different from that of DAST in the solution phase.…”

Bulk size crystal growth and physicochemical properties of ionic organic NLO crystal of DSMOS: A potential THz emitter

“…The spectrum gives two absorption peaks one at 476 and the other at 232 nm. It is well known that when DAST and its derivatives are dissolved in methanol, it leads to dissociated state generating free cations and anions [25]. This means that in order to absorb light in this region, the DSMOS molecule must contain p bonds and atoms with nonbonding orbitals.…”
