本論文量測水相中銅胺酸錯合物於313 nm照射下之一價銅量子產率。八種非極性胺酸配位基包括甘胺酸 (glycine, Gly)、α-丙胺酸 (alanine, Ala)、β-丙胺酸 (β-alanine, β-Ala)、2-胺基丁酸 (2-aminobutyric acid, 2-ABA)、2-胺基異丁酸 (2-aminoisobutyric acid, 2-AIBA)、4-胺基丁酸 (4-aminobutyric acid, 4-ABA)、纈胺酸 (valine, Val) 及正纈胺酸 (norvaline, Nor)。在不同條件（pH值與配位基濃度）下，利用bathocuproine之方法量測一價銅生成量並探討不同銅胺酸錯合物的一價銅量子產率關係。於313 nm光照下，一配位基的銅錯合物其一價銅量子產率 (ΦCu(I),CuL) 大小順序如下：2-AIBA ＞ β-Ala ＞ Ala，2-ABA，Nor ＞ Val ＞4-ABA ＞ Gly，範圍從0.279到0.06 (mol einstein-1)。不同實驗條件下，銅胺酸錯合物之光反應性，皆能以簡單之物種分佈模式預測。以碳為中心的自由基，其穩定性會對一價銅量子產率有重大的影響；形成六元螯合環的銅胺酸錯合物會比五元螯合環的銅胺酸錯合物有較大的一價銅量子產率，其可能原因為電子轉移效率增加。

Cu(I) quantum yields were measured at 313 nm for copper(II)-amino acid complexes with eight amino acids in aqueous solutions. Photochemical formation of copper(I) has been systematically studied for copper(II) complexes in different conditions (changing pH and ligand concentration). Bathocuproine method was used to determine copper(I) concentration. For the 1:1 Cu(II) complexes (CuL), the Cu(I) quantum yields at 313 nm (ΦCu(I),CuL) are in the sequence (25 0C, ionic strength = 0.10 M): 2-AIBA > β-ala > ala, 2-ABA, nor > val > 4-ABA > gly, ranging from 0.279 to 0.06 (mol einstein-1). Experimental data show that the photoreactivity of Cu(II)/amino-acid complexes can be predicted by Cu(II) speciation in a wide range of the solution conditions, varying in pH and the total concentration of ligand. The stability of the carbon-center radical plays an important role on the Cu(I) quantum yield. The six-membered chelate ring of Cu(II)/amino-acid complexes has larger Cu(I) quantum yields than five-membered chelate ring, probably owing to the increasing of the intra-molecular electron-transfer rate.
