Fluorene based polymers have been receiving much attention as promising component in luminescence devices. In this frame the related oligomers reached relevance either as polymeric models or as active layers. On these basis, three fluorenic-core tetramers have been synthetized via organosynthetic routes. The molecular, optical and electrochemical characterization of such oligomers in solution has...
We investigate relaxation processes in thiophene-based copolymers through site-selective and time-resolved photoluminescence spectroscopies. We observe a large Stokes-shift between the absorption and luminescence peaks that can be explained in terms of spectral relaxation of excitons within an inhomogeneously broadened density of states. The incoherent motion of the photoexcitations toward non radiative...
