University of Miami
Goal: The goal of this project was the identification of structural designs to switch fluorescence under optical control.
Results: The Laboratory of Molecular Photonics developed operating principles to switch the fluorescence of organic chromophores with either photocaged or photochromic components and characterized the spectroscopic signature of the resulting molecular constructs in liquid solutions, rigid matrices and biological samples.

The photoinduced cleavage of a diketone bridge activates anthracene fluorescence to allow energy transfer from the product to the reactant and ensure the autocatalytic generation of the former.
