These tetraphenylporphyrin-cored dendrimers present peripheral alkynyl π-conjugated dendrons with fluorenyl termini. The meso-aryl rings of these porphyrins are functionalized either in para- (TPP1, TPP2, and TPP3) or meta-positions (TPP4, TPP5, and TPP6). Their detailed luminescence properties are discussed in reference to two porphyrins lacking fluorenyl dendrons (TPP-H1,2,3 and TPP-H4,5,6 ). A strong dependence of their luminescence quantum yield and lifetime on their structures is stated, their nonlinear optical properties were also discussed %G English %L hal-01286284 %U https://univ-rennes.hal.science/hal-01286284 %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ ISCR %~ SCR_OMC2012 %~ SCR_CPM %~ STATS-UR1 %~ UR1-SPM %~ INC-CNRS %~ UR1-UFR-SPM %~ UR1-HAL %~ ISCR-CORINT %~ UR1-SDLM %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ ISCR-CORINT1 %~ UR1-MMS %~ ISCR-CORINT3 %~ TEST2-HALCNRS
