Résumé : In 2004, we synthesised a porphyrin possessing four fluorenyl arms (TFP), with a remarkable high quantum yield (24%), compared to the reference TPP, demonstrating the capacity of the fluorenyl units to enhance quantum yields. [1]- Then, to exploite this efficiency, a series of porphyrin dendrimers based on TPP porphyrin core and bearing fluorenyl dendrons was prepared like OOFTPP. [2] Different applications were exploited : as the fabrication of red Organic Light Emitting Diodes (OLEDs),- [3]- and supramolecular assemblies. [4]- Then a new family of conjugated porphyrin dendrimers, still based : based on TPP, is considered like TPP4,5,6. [5] Luminescence and non linear optical properties will be discussed.
