Orthogonal Bodipy Trimers as Photosensitizers for Photodynamic Action

Orthogonally linked BODIPY units shale exceptional intersystem crossing efficiencies. We now report orthogonal BODIPY trimers with strong absorption in the visible region and high singlet oxygen generation capability. The X-ray diffraction structure confirms that the two peripheral BODIPY units are at a perpendicular angle to the core structure.
