Their physicochem. and photophys. properties have been studied, compared and discussed in light of the nature of their resp. donor/acceptor units. The four compds. have been used as host materials in efficient sky-blue (EQE \textgreater 10% at 10 mA cm-2) phosphorescent org. light emitting diodes. %G English %2 https://univ-rennes.hal.science/hal-01198726/document %2 https://univ-rennes.hal.science/hal-01198726/file/Properties%20modulation%20of%20organic%20semi-conductors_accepted.pdf %L hal-01198726 %U https://univ-rennes.hal.science/hal-01198726 %~ CEA %~ X %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ ENSC-RENNES %~ X-PICM %~ X-DEP %~ X-DEP-PHYS %~ LPICM %~ ISCR %~ SCR_MACSE %~ STATS-UR1 %~ PUBNIMBE %~ UR1-SPM %~ GENCI %~ INC-CNRS %~ IRAMIS-NIMBE %~ CEA-UPSAY %~ UR1-UFR-SPM %~ UR1-HAL %~ UR1-SDLM %~ UR1-SDLMJONCH %~ UNIV-PARIS-SACLAY %~ CEA-UPSAY-SACLAY %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ ANR %~ UR1-MMS %~ IRAMIS %~ GS-CHIMIE %~ GS-PHYSIQUE %~ INSTITUT-SCIENCES-LUMIERE %~ TEST2-HALCNRS
