“…Conducting polymers (CPs) are particularly interesting materials for a number of applications, ranging from batteries to molecular electronic devices [1][2][3][4][5][6][7][8]. Among CPs, polythiophenes stand out thanks to peculiar electronic, optical, and electrochemical properties.…”

Electrochemical AFM technique has been used for the in situ study of the electrogeneration-deposition process of polybithiophene at varying the polymerisation conditions, such as supporting electrolyte, i.e., LiClO 4 or tetrabutylammonium hexafluorophosphate, and polymerisation procedure, i.e., either potentiostatic or potentiodynamic method. In order to better follow the evolution of the morphology of the deposit, particularly during the early stages of the polymer film growth, a suitable home-made electrochemical cell has been used.

Source of materialAt room temperture, to as olution of 36.2 go fs -trioxane in 35.5 ml of conc. hydrochloric acid was added dropwise and with stirring 15.0 gof2,5-dimethylthiophene. The blue mixture was stirred for three hours, diluted with 100 ml of water, and extracted with 50 ml petroleume ther.T he extracts were washed successively with diluted hydrochloric acid, water, 5% sodium bisulfite, and diluted sodium hydroxide. The solid obtained by evaporation of thesolventswas recrystallized from n-hexane by coolingthe solution andyieldingcolourlessblock-shapedcrystals (14 g, 49% yield).

ExperimentaldetailsAlln on-hydrogen atoms were refined anisotropically.

DiscussionThiophenes and their derivatives have been of interest for their useinnextgenerationelectronicmaterials owingtothe ease of production, synthetic versatility, and low cost compared to traditional inorganic materials [1][2][3]. As part of our work, we report the synthesis and crystal structure of the title compound. The asymmetric unit of the crystal structure is build up of one molecule. The C7-Cl1 and C8-Cl2 bond lengths arenearly identical at 1.808(3), 1.804(3) Å, respectively. TheC -C bonds within the thiophene are significantly shorter compared to other C-C bonds. The methyl as well as the carbon atomsofthe chloromethyl substituents C5, C6, C7 and C8 are alsonearly planar with respect to the central thiophene ring. Cl1 and Cl2 are not planar and locates above or below the thiophene ring.

“…To the best of our knowledge, reactivity of the -diketones containing thienyl moieties toward diamines has been scarcely reported in the literature [15]. The incorporation of thienyl units in the structure of a compound not only opens up opportunities to the formation of polymeric [16,17] and metallopolymeric materials [18,19], either through chemical or electrochemical oxidation of the thienyl units [20][21][22], but also to the development of new drugs [4].…”
