本論文主要探討鐵鐵氫化酵素，藉由化學合成方法來模擬目前已知的氫化酵素結構，以及結合光敏劑於仿氫化酵素之結構，在此合成含有光敏劑之結構[(u,k2-bdt-X)(u-PPh2)Fe2(CO)5] (X = 4,4''-dimethyl-2,2’-bipyridyl (1)，4,4''-dimethyl-2,2’-bipyridyl-ZnCl2 (2))。但在電化學研究中發現化合物被還原後有斷鍵的情形發生，並藉由紅外線光譜儀偵測還原反應，也證實此結果。為了解此鍵結，又合成不同衍生物之結構[(u,k2-bdt-X)(u-PPh2)Fe2(CO)5] (X = benzyl (3)，hexyl (4))，經由電化學以及還原反應結果得知，化合物3還原後依舊會斷鍵，而化合物4則不會有此情形發生。由以上結果幫助了解如何修正結構，使光敏劑與仿氫化酵素結合之結構可以更加穩定，以達到光催化之目的。 The synthesis and spectroscopic characterization as well as electrochemical study of diiron carbonyl dithiolate complexes, [(u,k2-bdt-X)(u-PPh2)Fe2(CO)5] (X = 4,4''-dimethyl-2,2’-bipyridyl (1) and 4,4''-dimethyl-2,2’-bipyridyl-ZnCl2 (2), benzyl (3), hexyl (4)) have been performedin this work. Electrochemistry of complexes 1-3reveals the formation of parent complex upon one electron reduction. This is confirmed by the chemical reduction reaction of complexes 1-3. This indicates that the rupture of S-C bond occurs when the species is reduced. Such phenomenon is not observed forcomplex 4.
