“…Porphyrins (Pors) are an all-pervading class of naturally occurring compounds with important biological representatives such as hemes, chlorophyll, and Vitamin B12. A basic structure of a Por macrocycle consists of four pyrrolic subunits linked by four methine bridges, and it is considered a related compound from Pcs. − Por synthesis has been extensively improved over the years, − and studied for a vast array of applications, including catalysis, − photomedicinal applications, − energy transfer, − and others. − …”

The control of luminous radiation has extremely important implications for modern and future technologies as well as in medicine. In this Review, we detail chemical structures and their relevant photophysical features for various groups of materials, including organic dyes such as metalloporphyrins and metallophthalocyanines (and derivatives), other common organic materials, mixed metal complexes and clusters, fullerenes, dendrimeric nanocomposites, polymeric materials (organic and/or inorganic), inorganic semiconductors, and other nanoscopic materials, utilized or potentially useful for the realization of devices able to filter in a smart way an external radiation. The concept of smart is referred to the characteristic of those materials that are capable to filter the radiation in a dynamic way without the need of an ancillary system for the activation of the required transmission change. In particular, this Review gives emphasis to the nonlinear optical properties of photoactive materials for the function of optical power limiting. All known mechanisms of optical limiting have been analyzed and discussed for the different types of materials.
