Our group has shown that fluorescence emission from photoswitchable rhodamine B dye molecules can be used to generate 3-dimensional images and animations in a volumetric light photoactivatable display. The 3D light structures are formed by cross-projecting UV and visible light beams simultaneously through a solution of photoswitchable fluorescent dye. The first generation of our 3D light PAD utilized photoactivatable red-emitting N-phenyl spirolactam rhodamine B derivatives. We have since built upon this to include multi-color display through synthesis of a fluorescent photoswitchable dyes with green emission. However, practical application of our 3D light PAD is limited by reaction kinetics. This talk will highlight the synthesis and characterization of various derivatives of both the red and green-emitting N-phenyl spirolactam rhodamine B derivatives in order to optimize reaction kinetics and quantum yields of the molecules.
