1. 近數年來的研究發現氧化鉛在強鹼溶液中會形成二主要之錯合物
PbIV(OH)62-， PbII(OH)3-。受到255 nm之紫外光照射時，二者會相互進
行氧化還原反應而達於一平衡狀態，同時會產生H2O2，其可分解污染物。
此外，二種物種分解時產生OH自由基( OH‧)，亦可分解污染物。
吾人製備氧化鉛粉末電極( PbOx powder electrodes)、氧化鉛薄膜電極(
PbOx thin-filmed electrodes )、氧化鉛沸石電極( PbOx zeolite
electrodes )等三種氧化鉛( PbOx)電極，並進行一些氧化鉛基本光電化
學的研究。2. 在本實驗室曾對光誘發氫離子轉移光閥進行研究，發現
啶 酸為一優良之敏光性物質，其光電效應隨環糊精之加入而增強。本論
文則研究敏光性物質( 啶 酸)與環糊精錯合反應，發現加入環糊精約為
啶 酸之4~5當量時，其光電效應已至飽合，此乃因環糊精與 啶 酸作
用所致。 啶 酸主要以 啶環與環糊精作用，而 啶 酸之烷基側鍊增
長則降低錯合之效應。推究其原因可能為凡得瓦力與氫鍵同時降低錯合反
應之能量。

1. In recent years , research finds that PbO in strong basic
solutions may produce PbIV(OH)62-, PbII(OH)3- species . Under
255 nm UV illumination , they can proceed redox reaction and
reach an equilbrium in between . In these reactions , H2O2 , one
of the by-products which can decompose pollutants . In these
degradation reactions , OH free radical may be produced and able
to decompose the pollutes .In this study , we prepare PbOx
powder electrodes, PbOx thin-filmed electrodes , PbOx zeolite
electrodes , and conduct a series of fundamental
characterization for them .2. Rescently, our laboratory studied
the photo-induced proton transfer reactions , and found
2-pyridylcarboxylic acids ( 2PCA ,2PAA , 3PPA ) are excellant
photo-induced proton transfer reagent . The photo-electric
effect of 2-pyridylcarboxylic acids is enhanced when
cyclodextrin (CD) is added . In this study , we find that the
ratio of 2-pyridylcarboxylic acids to CD is 1:4~5 , the effect
reaches a saturated value . This effect is caused by
2-pyridylcarboxylic acid--CD complex reaction . Besides , longer
alkane side chain reduces the complex ability with 2-pyridylcar-
boxylic acids . This is attributable to the van der Waal'sforce
and hydrogen bonding effect .
