Résumé
Fluorescent conjugated polymers formulated in nanoparticles show attractive properties to be used as bioimaging probes. However, their fluorescence brightness is generally limited by quenching phenomena due to interchain aggregation in the confined nanoparticle space. In this work, branched conjugated polymer networks are investigated as a way to enhance the photoluminescence quantum yield of the resulting conjugated polymer nanoparticles (CPNs). 1,3,5-Tribromobenzene and 2,2',7,7'-tetrabromo-9,9'-spirobifluorene are chosen as branching moieties and are added in 3 or 5 mol % to the poly(
