Real-time and real-space analysis of heavy and transition metal ions employing fluorescent sensor molecules has received much attention over the past few years. Since many of these cations possess intrinsic properties that usually quench the fluorescence of organic dye molecules, a lot of research has lately been devoted to designing fluorescent probes that show complexation-induced fluorescence enhancement. Such an analytical reaction would be highly desirable in terms of increased sensitivity and selectivity. However, in this particular field of sensor research, the photophysical and photochemical mechanisms involved as well as the chemical constitutions of the sensor molecules employed are rather diverse and up to now, very few attempts have been made to establish some general concepts for rational probe design. By analyzing various systems published by other researchers as well as own work, this contribution aims at an elucidation of some of the underlying principles of heavy and transition metal ion-enhanced emission.
在过去几年中，利用荧光传感器分子对重金属和过渡金属离子进行实时和实空间分析受到了广泛关注。由于这些阳离子中的许多具有通常会淬灭有机染料分子荧光的固有特性，近来很多研究致力于设计显示络合诱导荧光增强的荧光探针。就提高灵敏度和选择性而言，这样的分析反应将是非常可取的。然而，在传感器研究的这个特定领域中，所涉及的光物理和光化学机制以及所使用的传感器分子的化学组成相当多样，到目前为止，很少有人尝试为合理的探针设计建立一些通用概念。通过分析其他研究人员发表的各种系统以及自己的工作，本论文旨在阐明重金属和过渡金属离子增强发射的一些潜在原理。
