本研究以旋轉塗佈法將六種取代型金屬酞花青(MPc)鍍於玻璃基板上，以光學感測方法進行薄膜對胺類、酸類感測行為之研究，並利用分子模擬方法探討薄膜材料之穩態結構、氣體分子最佳吸附位置及電子光譜。
在胺類感測部分，探討(oct)ZnPc薄膜吸附不同結構之胺類氣體時，對UV-vis光譜吸收特性之影響。實驗結果顯示：
(1)胺分子碳鏈越長，其推電子能力越強。
(2)級數越低之胺類分子，N原子提供電子之能力越佳。
(3)雙胺的胺基數目較多，有效碰撞頻率也較高。
(4)戊胺異構物中，正戊胺之立體障礙效應最小。
(5) Aniline因具苯環共振結構，而降低N原子之lone pair密度。
上述(1)-(4)因素都能提高氣體靈敏性；反之，(5)會降低感測之靈敏度。另外，金屬酞花青薄膜對胺類之感測特性也受中間金屬與外緣取代基的影響。
在酸類感測部分，探討(oct)MPc與取代型ZnPc薄膜吸附不同碳鏈之酸類氣體時，對UV-vis光譜吸收特性之影響。研究結果顯示中間金屬以及外緣取代基皆會影響酞花青對酸類光學感測之靈敏性與選擇性。

In this study, thin films of six substituted metallophthalocyanines were spun unto glass substrates, and the changes of their UV-Visible spectra were investigated upon exposure to amine and acid vapors. Computational chemistry methods were also employed to simulate the gas adsorption process and the accompanying changes in the electronic spectra.

Changes of absorbance in the visible region were observed as the (oct)ZnPc film was exposed to organic amine vapors. Our results show that:
Effects of structure of the amines on sensitivity were studied to elucidate the sensing mechanism. The amine sensitivity is the largest for the primary amine, less for the secondary, and the least for the tertiary amines. For primary amines, the effect is in parallel to the alkyl chain length. Diamine shows a larger effect as compared to the simple amine, and some results can be explained in terms of the steric-hindrance effect of the amine substituents.

Changes of absorbance in the visible region were observed as thin films of the (oct)MPcs and substituted ZnPc were exposed to organic acid vapors. Our results show that both central metals and substituents play an important role in their optical gas sensing.
