本研究成功合成具有冠醚結構的化學感測器,其結構已透過NMR 1H、13C、Mass、HRMS確認。在乙腈溶劑中,分別加入等當量的金屬陽離子,量測其光物理性質。其中的分子5CA、6CA更可溶解於水溶液,在不同的酸鹼度下,也分別加入等當量的金屬陽離子,量測其光物理性質。
經金屬離子辨識,在乙腈溶液中5CM只對Cu2+有辨識能力,並透過競爭實驗,不會受到其他外加金屬離子影響,可以成為專門偵測Cu2+化學感測器分子的候選者;6CM只對Pb2+、Cu2+有辨識能力,;5CA對許多金屬離子都有辨識能力,其中對Fe3+會使螢光強度淬息的程度較大;6CA也對許多金屬離子都有辨識能力,其中對Ca2+會使螢光強度增強高達840%。
由化合物5CA、6CA在不同酸鹼度的水溶液中對金屬離子的辨識實驗,其結果都沒有選擇性。但5CA、6CA在酸性環境下,最大吸收峰、放光峰波長會紅移、螢光強度淬息,此可應用於偵測在酸性環境下的酸鹼度。
In this study, the chemical sensors with crown ether structure were successfully synthesized and their structure were confirmed by NMR 1H, 13C, Mass, and HRMS. An equivalent amount of metal cations were added to measure the photophysical properties in acetonitrile. 5CA and 6CA could be dissolved in aqueous solution. They were added equal amounts of metal cations to measure their photophysical properties in aqueous solution of different pH value.
According to the identification of metal ion, 5CM only had the ability to identify Cu2+ in acetonitrile. Through the competition experiment, it would not be affected by other external metal ions. So it could become the candidate of chemical sensor molecule to be specifically detect Cu2+. 6CM only had the ability to identify Pb2+ and Cu2+ in acetonitrile. 5CA had the ability to identify Fe3+ in acetonitrile, which made the fluorescence intensity quench at most. 6CA had the ability to identify Ca2+ in acetonitrile, which made the fluorescence intensity increase up to 840%.
In acidic condition, the maximum absorption peak and the emission peak wavelength of 5CA and 6CA would be red-shift and made fluorescence intensity quench. As a result, they could be used to detect the pH value in acidic condition.
