The morphology and the kinetic and thermal stability of the organic nanoparticles were also investigated.RSC advancesPeripherical thioester functionalization induces <i>J</i>-aggregation in bithiophene-DPP films and nanoparticles.PMC8695947PRA_2020_21Blasi DComparelli ROperamolla APunzi AFarinola GMPalazzo GfalsePeripherical thioester functionalization induces <i>J</i>-aggregation in bithiophene-DPP films and nanoparticles.In this work we demonstrated that the peripherical thioacetylation of a bithiophene-DPP molecule can greatly influence the solid-state properties triggering the formation of NIR emitting <i>J</i>-aggregates in both bithiophene-DPP films and nanoparticles.
