Micropatterns of [Fe-Fe]-Hydrogenase Active-Site Model Complexes Fabricated by Electro-Oxidative Lithography

[Fe-Fe]-hydrogenase active site model complexes ([Fe(CO)3]2[(μ-SCH2)2C(CH2OH)2]) were immobilized on micropatterned n-octadecyltrichlorosilane (OTS) monolayers deposited on a Si substrate to form a microscale catalytic system. The micropatterns were generated by electro-oxidative lithography perform...

520 |a [Fe-Fe]-hydrogenase active site model complexes ([Fe(CO)3]2[(μ-SCH2)2C(CH2OH)2]) were immobilized on micropatterned n-octadecyltrichlorosilane (OTS) monolayers deposited on a Si substrate to form a microscale catalytic system. The micropatterns were generated by electro-oxidative lithography performed with a conductive TEM grid. The [Fe-Fe]-hydrogenase active-site complex molecules were selectively anchored in lithographic line areas with good coverage. Additionally, the biomimetic metal centers of the hydrogenase active-site complex molecules still maintained their catalytic activity and their redox-active properties after the immobilization process, which was proven by cyclic voltammetry
