The photophysics of photosensitization: A brief overview

open access: yesJournal of Photochemistry and Photobiology, 2021
The concept of photosensitization had its origins in the serendipitous discovery in the 19th century that dye molecules could enhance the spectral range of photographic emulsions.

Photosensitization and controlled photosensitization with BODIPY dyes [PDF]

open access: yesCoordination Chemistry Reviews, 2019
Abstract Highly versatile BODIPY dyes proved themselves to be very useful as photosensitizers. These dyes can be derivatized to absorb essentially anywhere in the visible the near IR region of the spectrum. As a result of their diverse reactivity, singlet oxygen generation efficiency can be modulated very precisely, leading to a number of selective ...
