本論文主要是在架構在硫酸銅會與吡嗪(pyrazine)可形成交錯排列的一維配位錯合物(如附圖所示),而在表面或奈米尺度孔洞環境中,生長奈米尺寸的錯合物導線,以備未來的分子電子元件應用。。
第一部份是在金表面製作條紋化的8-(4-吡啶)辛烷硫醇/辛烷硫醇單層分子薄膜,再將此金片放入硫酸銅與吡嗪的混合液中,在金片上的具吡啶區塊上長出分子導線,而形成在特定區塊才能高起的區塊。另外也在金表面吸附均勻分散的8-(4-吡啶)辛烷硫醇/辛烷硫醇的混合單分子薄膜,再將此一矽晶片放入硫酸銅與吡嗪的混合液中,希望可以藉著吡啶官能基的均勻分散而使得分子導線能分開獨立生長。
第二部分是利用奈米孔徑的AAO(Anodized aluminum oxide)作為版模;以兩相的方式,讓吡嗪溶液及硫酸銅溶液擴散到AAO裡面反應,而在AAO裡面形成晶體線;以及在金奈米粒子上吸附8-(4-吡啶)辛烷硫醇來取代吡嗪,與銅離子在AAO中反應,將金奈米粒子串連形成奈米金線。
The thesis based on the observation that copper ion reacts with pyrazine to form crystals of infinite one-dimensional alternating complex. Growth of such complexes on a functional surface or nano-scale channels to give nanometer scale, isolated complex wires is studied for the potential application in molecular electronic device fabrication.
The first part involves the preparation of patterned monolayer surface of 8-(4-pyridyl)octanethiol/octanethiol. Immersion of the patterned surface into mixture of copper ion and pyrazine led to formation of complex specifically on pyridine-containing areas. Mixed monolayers of 8-(4-pyridyl)octanethiol and octanethiol were then prepared for the selective growth of complex crystals on isolated pyridine sites in order to obtain isolated wires.
The second part involves nanometer scale channels of anodized aluminum oxide (AAO) as the template for formation of complex crystals. Through a two phase approach, copper ions and pyrazine molecules were allowed to diffuse, mix and react in the channels of AAO to form nano wires of complexes. Also, the pyrazine was replaced by nanometer gold particles covered with 8-(4-pyridyl)octanethiol so that reaction with copper in the channels of AAO gave strings of gold nano particles.
