“…There are, however, other molecules, which, despite being non-amphiphilic, can form stable Langmuir and LB films. Among them are such dyes as rhodamine B [6], pyrene [7], porphyrins [8,9], phthalocyanines [9,10], derivatives of perylene [11 -14], derivatives of fluorescein [15], and derivatives of naphthoylenebenzimidazole [16 -21]. Some years ago it was found in our laboratory that also several derivatives of 1,8-naphthalimide can create stable monolayers at interfaces [16 -20].…”

Langmuir and Langmuir-Blodgett (LB) films formed of some fluorescent dyes, derivatives of 4-aminonaphthalimide, and their binary mixtures with the liquid crystal 4-heptyl-4 -cyanobiphenyl (7CB) have been studied. Surface pressure versus mean molecular area isotherms for Langmuir films have given information about the alignment of molecules in a monomolecular layer at the air/water interface. The absorption and fluorescence spectra of LB films have revealed the occurrence of aggregates among dye molecules. In the ground electronic state some fraction of aggregates of J-type have appeared, while in the excited state the excimers have been created. The latter statement has been confirmed by additional absorption and fluorescence measurements performed for dyes dissolved in 7CB and placed in sandwich cells of 10 µm in thickness.

“…Moreover, for the newly developed technology, namely the organic solar cells of last generation, it has important significance because they have very interesting properties and many advantages [1][2], including the cell flexibility and the ability to be exploited in large areas, the low costs of materials and organic cells fabrication [3][4]. However, the improvement of efficiency and stability must be considerably compared to their current state.…”

In this paper, the characterization and modeling results of the electrical parameters of the tendem organic photovoltaic cells (infinityPV) are presented. The electrical performances of this organic cell's module (I-V and P-V) are characterized and analyzed in the weather condition of southwest Algeria (Adrar site). A program in MATLAB language is developed locally for modeling the organic cell, using artificial intelligence. The multilayer feed forward perception type ANN is used for extraction of the organic photovoltaic model performances, and the back-propagation algorithm is used for the program training. The ANN obtained results by the simulation showed a good conformity with the results obtained experimentally in the saharan climate (MAPE:0.68%, MBE:4.5018e-09 A and RMSE:1.8062e-04 A).

A self assembled films (SA) of cupper phthalocyanine (CuPh) chemisorbed on the mild steel sur face was coated by an inorganic organic sol gel hybrid coating. Hybrid sol was synthesized via acid catalyzed hydrolysis and condensation of methacryloxypropyl trimethoxysilane (TMSM) and tetraethoxysilane (TEOS) at the molar ratio of 1 : 1. The morphology of mild steel coated with TMSM/TEOS and CuPh was examined by SEM. The surface chemistry of the hybrid sol gel coatings was investigated with polarization scans and electrochemical impedance spectroscopy (EIS) in aerated 0.5 mol L -1 HCl solution. Self assem bled CuPh films coated under the hybrid coating showed a strong influence on its corrosion resistance, mainly when the samples have 24 h immersion time and 1 mM concentration.
