Langmuir and Langmuir-Blodgett films of NLO active 2-(p-N-Alkyl-N-methylamino)benzylidene-1,3-indandione-pi/A curves, UV-vis spectra, and SHG behavior

Article Abstract:

Two-(p-N-Alkyl-N-methylamino) benzylidene-1,3-indandione (1a) as model compound for the preparation of nonlinear optically (NLO) active Lanfmuir-Blodgett(LB) layers is studied. The study observed that the two main spectral bands in the LB films, and which can be deconvoluted form the solution spectra can be assigned to two nearly intrinsic molecular transitions, or to transitions associated with different conformers f the molecules.

Quinolinium-derived acentric crystals for second-order NLO applications with transparency in the blue

Article Abstract:

Research has been conducted on the quinolinium iodide derivatives in crystalline form found to exhibit nonlinear optical response. Direct correlation between second harmonic generation powder response to the beta crystallographic angle has been observed.
