“…Poly(octyl methacrylate- co -vinylimidazole [ 10 ], polystyrene, polyacrylonitrile [ 11 ], and poly(arylene ether sulfone) [ 16 ] have been used in the manufacture of membranes along with MPcs; however, these membrane applications were not intended for optoelectronic devices. Therefore, the Nylon 11 offers a viable option for the manufacture of semiconductor membranes as described in our previous studies [ 17 ]. The amide linkages in the chain provide these properties, among others, through the hydrogen bonds, allowing a solid interaction between the chains.…”

“…The amide linkages in the chain provide these properties, among others, through the hydrogen bonds, allowing a solid interaction between the chains. Also, molecules that create hydrogen bonds can penetrate and interfere in the inter-chain hydrogen bonds weakening the hydrogen bond network [ 17 ]. Due to Nylon low permeability it is frequently used as a bagging material during shipping or storage.…”

It is known that one factor that affects the operation of optoelectronic devices is the effective protection of the semiconductor materials against environmental conditions. The permeation of atmospheric oxygen and water molecules into the device structure induces degradation of the electrodes and the semiconductor. As a result, in this communication we report the fabrication of semiconductor membranes consisting of Magnesium Phthalocyanine-allene (MgPc-allene) particles dispersed in Nylon 11 films. These membranes combine polymer properties with organic semiconductors properties and also provide a barrier effect for the atmospheric gas molecules. They were prepared by high vacuum evaporation and followed by thermal relaxation technique. For the characterization of the obtained membranes, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and energy dispersive spectroscopy (EDS) were used to determine the chemical and microstructural properties. UV-ViS, null ellipsometry, and visible photoluminescence (PL) at room temperature were used to characterize the optoelectronic properties. These results were compared with those obtained for the organic semiconductors: MgPc-allene thin films. Additionally, semiconductor membranes devices have been prepared, and a study of the device electronic transport properties was conducted by measuring electrical current density-voltage (J-V) characteristics by four point probes with different wavelengths. The resistance properties against different environmental molecules are enhanced, maintaining their semiconductor functionality that makes them candidates for optoelectronic applications.

“…The value of the optical activation energy, attributed to the lower energy transition that takes place by a photon absorption, is estimated by UV-vis spectroscopy. In order to calculate the energetic spacing, different methods are applied, the most common for amorphous films being the Tauc method [ 7 , 10 , 39 ]. It consists in the extrapolation of the linear stretch of the skirt of the lower energy band of the absorption coefficient (α hv ) 1/2 for indirect transitions (see Figure 5 b), up to the cutoff point with the abscissa axis corresponding to the energy of the photon ( hν ).…”

“…This involves the use of organic semiconductors with optoelectronic properties which selectively stimulate the conduction of one type of carrier [ 6 ]. Different materials have been used as organic semiconductors, such as metallophthalocyanines (MPcs), tetrathiafulvalene (TTF) [ 7 ], perovskites [ 8 ], fullerene [ 9 ] and tetracyanoquinodimethane (TCNQ) [ 10 ]. However, only a few materials such as carbazoles [ 6 ], copper phthalocyanine (CuPc) [ 11 ], pentacene [ 12 ], carbon nanotubes [ 13 ] and poly(3,4-ethylenedioxythiophene) (PEDOT) have been studied as HTLs, [ 14 ]; or as ETLs (e.g., bathocuproine (BCP) [ 15 , 16 ], naphthalic anhydride and bathophenanthroline (BPhen) [ 2 ]).…”

A new series of Fischer carbenes have been synthetized and examined as hole-transporting or electron-transporting layers (HTLs or ETLs) in the fabrication of organic solar cells (OSCs). The synthesis of three Fischer aminocarbene complexes with the general formula [Cr(CO)5{C(NHCH2)Ar}] (Ar = 2-pyridyl (3a), 3-pyridyl (3b) and 4-pyridyl (3c)) is reported. The molecular structure of complex 3b has been confirmed by X-ray analysis. In order to study the possible applications of the three Fischer aminocarbenes in OSCs, thin films of these complexes were prepared using a vacuum deposition process. These organometallic films were chemically and morphologically characterized by IR spectroscopy, SEM, AFM and XRD. According to the IR and Tauc analysis, the vacuum deposition process generates thin films free of impurities with an activation energy of 4.0, 2.7 and 2.1 eV for 3a, 3b y 3c, respectively. The UV-vis spectra of the amorphous aminocarbene films show that they are practically transparent to the visible radiation of the electromagnetic spectrum. This is due to the fact that their absorption is located mainly in the ultraviolet range. Two OSCs with bulk-heterojunction configuration were manufactured in order to prove the use of the aminocarbenes as ETL o HTL. The aminocarbene [Cr(CO)5{C(NHCH2) 4-pyridyl}] (3c) proved to be suitable as ETL with a fill factor (FF) of 0.23 and a short circuit current density (JSC) of 1.037 mA/cm2.
