In recent years, circularly polarized luminescence (CPL) has witnessed a renaissance, due to the increased popularity of CPL as a spectroscopic technique and greater accessibility to instrumentation. New efficient CPL emitters have been designed and many applications, ranging from electronic devices to microscopy have been proposed. Most examples of CPL are within the visible range, while few cases of near infrared (NIR) CPL active complexes are available. NIR-CPL compounds may have applications in the telecommunication industry, electronic devices and bioassays. In the following, we shall give an overview of the recent developments allowing for the measurements of NIR-CPL, and describe the chiroptical properties of metal complexes which achieve this feat.
近年来,圆偏振发光(CPL)由于作为一种光谱技术的普及度增加以及对仪器的更高可及性,重新受到关注。已经设计了新的高效 CPL 发射器,并且提出了从电子设备到显微镜的许多应用。CPL 的大多数实例都在可见光范围内,而近红外(NIR)CPL 活性配合物的情况很少。NIR-CPL 化合物可能在电信行业、电子设备和生物测定中有应用。在下面,我们将概述允许测量 NIR-CPL 的最新发展,并描述实现这一壮举的金属配合物的手性光学性质。
