文摘

A new hybrid material with dual UV/vis light-harvesting ability has been prepared based on PM546 dye confined in zeolite L nanochannels. Besides the characteristic vis green-yellow absorption of the dye in solution, a new band arises due to specific host鈥揼uest interactions, spanning the UV and blue edge of the vis. A chemical reaction takes place between the PM546 and acid protons from the zeolite, removing a fluorine atom from the BODIPY and giving rise to the new hypsochromic absorption. As result, a single dye presents light absorption at two different wavelengths, as well as a broad fluorescence emission, which covers a wide part of the vis region through a FRET process.
