摘要

利用有機無機混成材料 (OIHM) 可以將有機染色基團結合於無機的骨架中。在具有給受體的矽凝膠系統中能量轉移以及電子轉移已經被證實。在此論文中將有機分子引入到磷鋁溶膠凝膠系統。利用了含有膦酸基的共軛基團當作給受體，並與Al(lact)3 進行溶膠凝膠反應，形成有一到多個發光團的新勻相有機無機混合材料。利用核磁光譜來研究此一新材料的結構，並對此新混合材料作了許多光物理測試。發現在此新的有機無機凝膠系統中，可以藉著激發給體來進行給受體之間的能量轉移。並且在隨著給體比例增加可以發現受體的螢光強度也增加，證明了光收成的效果。我們成功了模仿大自然的光收成現象。我們也在此新凝膠系統中測試了電子轉移，我們也發現了相當好的結果

Efficient OIHM has been used to integrate organic chromophores into inorganic frameworkref. FRET and electron transfer have observed in these system. Al-P inorganic materials is isoelectronic to the silicon-based lattice. However, these might be charge separation in the Al-P materials . In this regard the framework many provide a different environment for the incorporated organic moieties. In this work, we present for the first time the synthesis, fabrication, and photophysics of oligoaryl-Al-P hybrid materials.
In this thesis, we used different kinds of oligoaryl that contain diphosphonic acid group as donor and acceptor. And reacted with Al(lact)3 to do the sol-gel process, to form a new homogeneous organic-inorganic hybrid materials. We used solid-state NMR to study the structure of this new hybrid material. We also did many photophysics studies, we discovered that when excited the donor there be energy transfer in this organic-inorganic sol-gel system. And we can see that changed the ratio of donor and acceptor accompanied the increasing of the donor emission, that prove the light harvesting in our new materials were very efficient. And we also tested the electron transfer in this new sol-gel system, also got excellent results.
