Origin of the photoinduced optical second harmonic generation arising in N-phenyl microcrystalline films
Article Abstract:
Optical second harmonic generation (SHG) and photoinduced second-order nonlinear optical effects of N-phenyls with different numbers of aromatic rings deposited on glass substrates were studied. A strong dependence of the photoinduced SHG versus the number of aromatic rings determining the degree of film crystallinity was seen and it was found that for the photoinduced first-order nonlinear optical effect the dominant contribution is an amorphous-like structure component.

Conjugated polymer/molten salt optimization
Article Abstract:
The importance of finding optimized conditions to produce the molten salt-polymer blends best suited for favoring electron and hole injection in thin layer electrochemical cells is highlighted. Electric force microscopy measurements show that increasing the salt content results in producing a reduced number of larger salt domains, so that the overall perimeter of the discotic salt domains exhibits a maximum as a function of the salt concentration in the solution.
