Abstract
Abstract A series of porphyrin monomers bearing four n -butyl substituted fluorenyl donor groups is presented; successively, intermediate compounds 1 (TMS protected), 2 (possessing an acetylene group) and corresponding zinc complex 3 have been synthesized. Starting from these building blocks, new extended Dimer, with in totally 9 fluorenyl groups, has been obtained and fully characterized. For the first time two highly luminescent tetrafluorenylporphyrin units ( TFP ) are connected to form a linear geometry and in addition, a rigid 2,7-fluorenyl linker was selected to connect these building blocks. The luminescence properties were compared with TFP monomer, dimer and trimer described earlier by our group.
