卟啉和相关家族的分子是重要的有机模块，这已经反映在1915年、1930年、1961年、1962年、1965年和1988年的诺贝尔化学奖中，以表彰卟啉相关生物功能的工作。卟啉核可以通过引入各种官能团和其他元素来合成改性，从而允许产生多种类型的卟啉衍生物。这一特征使得卟啉分子非常有用，特别是与它们其他有趣的光子，电子和磁性特性相结合，这反过来又反映在它们基于与其他分子和外部刺激相互作用的不同信号输入-输出功能中。因此，卟啉和相关的大环化合物在涉及发色团的传感应用中起着突出的作用。在这篇综述中，我们讨论了卟啉为基础的传感应用的最新进展，结合新的先进概念的nanoarchitectonics，创建功能性纳米结构的基础上深刻理解的相互作用之间的个别纳米结构和它们的任意安排。卟啉化学和物理学的基础知识的简要解释，最近的例子在相应的领域进行了讨论，根据分类的基础上的物理模式的检测，包括光学检测（吸收/光致发光光谱和能量和电子转移过程），其他光谱模式（圆二色性，等离子体和核磁共振），电子和电化学模式，和其他传感模式。
Porphyrins and related families of molecules are important organic modules as has been reflected in the award of the Nobel Prizes in Chemistry in 1915, 1930, 1961, 1962, 1965, and 1988 for work on porphyrin-related biological functionalities. The porphyrin core can be synthetically modified by introduction of various functional groups and other elements, allowing creation of numerous types of porphyrin derivatives. This feature makes porphyrins extremely useful molecules especially in combination with their other interesting photonic, electronic and magnetic properties, which in turn is reflected in their diverse signal input-output functionalities based on interactions with other molecules and external stimuli. Therefore, porphyrins and related macrocycles play a preeminent role in sensing applications involving chromophores. In this review, we discuss recent developments in porphyrin-based sensing applications in conjunction with the new advanced concept of nanoarchitectonics, which creates functional nanostructures based on a profound understanding of mutual interactions between the individual nanostructures and their arbitrary arrangements. Following a brief explanation of the basics of porphyrin chemistry and physics, recent examples in the corresponding fields are discussed according to a classification based on physical modes of detection including optical detection (absorption/photoluminescence spectroscopy and energy and electron transfer processes), other spectral modes (circular dichroism, plasmon and nuclear magnetic resonance), electronic and electrochemical modes, and other sensing modes.
