Poly(3,4-ethylenedioxythiophene) (PEDOT) and its derivatives have demonstrated potential in the development of bioelectrodes because of their superior conductivity However, developing reliable implanted bioelectrodes requires improvements in biocompatibility and the prevention of nonspecific adhesion. In this study, a six ethylene glycol (EG)-functionalized EDOTs with three different EG lengths (tri-EG, tetra-EG, and hexa-EG) and two types of end groups, hydroxyl (-OH) and methoxy (-OCH3) is synthesized and systematically investigated. By coating them on gold electrodes using electropolymerization, the surface and electrochem. properties of these functionalized PEDOT-coated electrodes are investigated. Although PEDOT with -OH groups on the surface is more hydrophilic, those with -OCH3 groups on the surface exhibit higher electrochem. activity and lower impedance. The increase in EG units and -OCH3 groups on the surface effectively reduces the adhesion between the PEDOT and at. force microscopy tips. PEDOT with longer EG lengths and -OCH3 groups exhibits relatively few adhered platelets, and the results of the anal. of hydrated states through differential scanning calorimetry are consistent with those of the platelet adhesion test. This study suggests that a tetra(EG)-functionalized PEDOT with -OCH3 groups on the surface is a promising coating for implanted bioelectrode applications. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5SDS of cas: 76-83-5).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.SDS of cas: 76-83-5
