Synthesis and Characterization of new Conjugated Fluorenyl-Porphyrin
Dendrimers for Optics
In 2004, we synthesised a porphyrin possessing four fluorenyl arms (TFP),[1] with a remarkable high quantum yield (24%), compared to the reference TPP, demonstrating the capacity of the fluorenyl units to enhance quantum yields. Then, to exploite this efficiency, a series of porphyrin dendrimers based on TPP porphyrin core and bearing fluorenyl dendrons was prepared like OOFTPP.[2,3] Different applications were exploited : as the fabrication of red Organic Light Emitting Diodes (OLEDs),[4-6] and supramolecular assemblies.[7] Then a new family of conjugated porphyrin dendrimers, still based: based on TPP, is considered like TPP6. [8] Luminescence and nonlinear optical properties will be discussed discussed.
