Abstract
A family of red light-emitting star-shaped porphyrins with four monodisperse conjugated oligofluorene arms was prepared by using two key reactions: Lindsey condensation and Suzuki−Miyaura cross coupling reactions. All porphyrins exhibit high quantum yields (about 0.22) and good solubility in common organic solvents, and form high-quality solid films. Optical studies showed that the star-shaped oligomers could absorb blue light and emit saturated red light via efficient energy transfer from the fluorene segments to the porphyrin core.Keywords
