Kinetic and Mechanistic Investigation of Electrochemical Oxidation of Hydroquinones in the Absence and Presence of 2-acetyl-gamma-butyrolactone

Progress in Reaction Kinetics and Mechanism (2014)

Mohsen Ameri Alireza Asghari Ali Amoozadeh Davood Nematollahi Mansour Arab Chamjangali

Electrochemical oxidation of hydroquinones (1a,b) was studied in the presence of 2-acetyl-gamma-butyrolactone (3) as nucleophile in phosphate buffer solution (pH 7.0 and c = 0.15 mol L −1 ):ethanol (80: 20), using cyclic voltammetry and controlled potential coulometry. The results indicated that the p-benzoquinone derived from (1a,b) participates in 1,4-Michael addition reaction with 3 via an EC mechanism which produces the relatively new hydroquinone derivatives (5a,b). The electrochemical synthesis of (5a,b) has been successfully performed on carbon rod electrodes in an undivided cell. Furthermore, the observed homogeneous rate constants of the reaction between hydroquinones and 2-acetyl-gamma-butyrolactone were estimated by comparing the experimental cyclic voltammograms curves with those digitally simulated.

Green and Highly Efficient Synthesis of New Bis-benzofurans via Electrochemical Methods under ECECCC Mechanism

Journal of The Electrochemical Society (2014)

Mohsen Ameri Alireza Asghari Ali Amoozadeh Mohammad Bakherad Davood Nematollahi

Oxidation of hydroquinone (1a) has been studied in the presence of methyl cyanoacetate (3a) and ethyl cyanoacetate (3b) as nucleophile in phosphate buffer solution (0.2 M, pH 7) mixed with ethanol as a green solvent (80:20 v:v) using cyclic voltammetry and coulometry, under constant potential. The obtained results indicated that p-quinone derived from electro-oxidation of hydroquinone (1a), participated in 1,4-Michael addition reactions with cyanoacetate derivatives (3a-3b) via ECECCC mechanism (E:electrochemical and C: chemical). In the present study, new benzofuran derivatives were synthesized in good yields and high purity using a facial, one-pot and environmental electrochemical method by 3 carbon electrodes in an undivided cell, without any chemical reagent and hazardous solvents.

A Facile and Efficient One‐Pot Electrochemical Synthesis of Thiazole Derivatives in Aqueous Solution

Helvetica Chimica Acta (2015)

Mohsen Ameri Ali Amoozadeh Alireza Asghari Davood Nematollahi Mohammad Bakherad

Abstract In the present work, the electrooxidation of hydroquinones 1a and 1b , and catechols 1c and 1d was studied in the presence of rhodanine ( 3 ) as nucleophile in a mixture of EtOH and phosphate buffer solution as ‘green’ media using cyclic voltammetry and controlled‐potential coulometry. The results indicated that the corresponding p ‐ and o ‐quinones formed from the hydroquinones and catechols, respectively, participate in Michael addition reaction to yield new thiazole derivatives. The electrochemical syntheses of these new thiazole derivatives were performed successfully at three graphite rod electrodes in undivided cells in good‐to‐excellent yields at room temperature without any catalyst.

Organic/Organic Heterointerface Engineering to Boost Carrier Injection in OLEDs

Scientific Reports (2017)

Mohammadreza Fathollahi Mohsen Ameri Ezeddin Mohajerani Ebrahim Mehrparvar Mohammadrasoul Babaei

Abstract We investigate dynamic formation of nanosheet charge accumulations by heterointerface engineering in double injection layer (DIL) based organic light emitting diodes (OLEDs). Our experimental results show that the device performance is considerably improved for the DIL device as the result of heterointerface injection layer (HIIL) formation, in comparison to reference devices, namely, the current density is doubled and even quadrupled and the turn-on voltage is favorably halved, to 3.7 V, which is promising for simple small-molecule OLEDs. The simulation reveals the (i) formation of dynamic p-type doping (DPD) region which treats the quasi Fermi level at the organic/electrode interface, and (ii) formation of dynamic dipole layer (DDL) and the associated electric field at the organic/organic interface which accelerates the ejection of the carriers and their transference to the successive layer. HIIL formation proposes alternate scenarios for device design. For instance, no prerequisite for plasma treatment of transparent anode electrode, our freedom in varying the thicknesses of the organic layers between 10 nm and 60 nm for the first layer and between 6 nm and 24 nm for the second layer. The implications of the present work give insight into the dynamic phenomena in OLEDs and facilitates the development of their inexpensive fabrication for lighting applications.

Facile and clean electrochemical synthesis of new acetaminophen derivatives through electrochemical oxidation of acetaminophen in the presence of thiouracil derivatives

Journal of Sulfur Chemistry (2016)

Alireza Asghari Mohsen Ameri Samira Taghipour Omid Ghaderi

The electrochemical oxidation of acetaminophen (1a) is carried out in the presence of thiouracil derivatives (3a–c), as nucleophiles, in an acetate buffer solution (0.15 M, pH 5) mixed with Dimethylformamide (DMF) using cyclic voltammetry and coulometry under a constant potential. The results obtained indicate that N-acetyl-p-benzoquinone-imine derived from acetaminophen participates in a 1,4-Michael-type addition reaction with thiouracils to form the corresponding acetaminophen derivatives (4a–c) in good yields and with high purities using a facile, catalyst-free, and one-pot electrochemical method using three carbon electrodes in an undivided cell under mild conditions. The products obtained were characterized after purification by IR, 1H NMR, and 13C NMR spectroscopies, and by the elemental analysis method.

Facile realization of efficient blocking from ZnO/TiO₂mismatch interface in dye-sensitized solar cells and precise microscopic modeling adapted by circuit analysis

Journal of Physics D Applied Physics (2016)

Mohsen Ameri Feridoun Samavat Ezeddin Mohajerani Mohammadreza Fathollahi

In the present research, the effect of -based blocking layers on the operational features of -based dye-sensitized solar cells is investigated. A facile solution-based coating method is applied to prepare an interfacial highly transparent compact blocking layer (CBL) to enhance the efficiency of dye-sensitized solar cells. Different precursor molar concentration were tested to find the optimum concentration. Optical and electrical measurements were carried out to confirm the operation of the CBLs. Morphological characterizations were performed by scanning electron microscopy (SEM) and atomic force microscopy (AFM) to investigate the structure of the compact layers. We have also developed a set of modeling procedures to extract the effective electrical parameters including the parasitic resistances and charged carrier profiles to investigate the effect of CBLs on the dye-sensitized solar cell (DSSC) performance. The adopted modeling approach should establish a versatile framework for diagnosis of DSSCs and facilitates the exploration of critical factors influencing device performance.
