研究了双（四甲基胍）丙烷、碘化亚铜（I）和[Cu（btmgp）I]的乙腈溶液的荧光性质，并研究了后者在室温下与O2的化学反应.通过O2气体的实际猝灭过程进行了研究，并观察到相对于复杂的浓度的荧光强度的指数依赖。此外，还对[Cu（btmgp）I]溶液在较宽浓度范围内的时间分辨荧光性质进行了深入的研究。通过共聚焦荧光测量证明了该复合物在微反应器系统内用于O2传感的适用性。结果表明，该体系可用于铜浓度在10 - 2 ~ 10 - 9 mol/l范围内的氧传感。
A fluorescence study of acetonitrile solutions of bis(tetramethylguanidine)propane, copper(I)-iodide and [Cu(btmgp)I] was performed and the chemical reaction of the latter species with O2was investigated at room temperature. The actual quenching process via O2gassing was studied and an exponential dependence of the fluorescence intensity with respect to the complex concentration was observed. Furthermore the survey was deepened on time resolved fluorescence properties of solved [Cu(btmgp)I] in a wider concentration range. The applicability of this complex for O2sensing inside a microreactor system was proven by confocal fluorescence measurements. It was shown that the investigated system can be used for oxygen sensing in the copper concentration range from 10−2to 10−9mol/l.
