| Abstract: | Five-membered-ring fused BODIPYs and aza-BODIPY were herein prepared. X-ray crystallographic analysis revealed that the core skeleton of six-membered-ring fused BODIPY is nonplanar but twisted. Such five-membered-ring fused BODIPY/aza-BODIPY dyes have long wavelength absorptions/emissions, high extinction coefficients, peak fluorescence and narrow excitations/emissions. MO calculations well supported and explained the same absorption maxima between BODIPY bearing the five-membered ring and BODIPY bearing the six-membered ring. |
