Abstract
A novel sensor (RD) bearing rhodamine B and 4-tert-Butyl phenol unit have been designed and synthesized using microwave irradiation. The sensor allows selective detection of Cu by forming absorptive complex and trigger the formation of highly colored ring-open spirolactam. The recognition ability of the sensor was investigated by absorbance, Job's plot, infrared (IR) and time dependent-density functional theory (TD-DFT) calculations.
摘要
一种带有罗丹明B和4-叔丁基苯酚单元的新型传感器（RD）已通过微波辐射设计并合成。该传感器通过形成吸收性络合物实现对铜的选择性检测，并引发高显色性的开环螺内酰胺的形成。通过吸光度、乔布氏图、红外（IR）光谱以及含时密度泛函理论（TD-DFT）计算对该传感器的识别能力进行了研究。
