TLDR
In this paper, a quantitative intramolecular energy transfer from the anthracene donor to the emitting porphyrin acceptor through the oligothiophene chain after selective UV excitation of Anthracene was demonstrated.Abstract:
In the new trichromophoric supermolecule 1, a quantitative intramolecular energy transfer (>98 %) occurs from the anthracene donor to the emitting porphyrin acceptor through the oligothiophene chain after selective UV excitation of anthracene. Energy-transfer properties and fluorescence quantum yields are independent of the oligothiophene chain length. Attachment of further anthrylquinquethienyl chromophores to the porphyrin ring results in an increase in the intensity of characteristic absorption and fluorescence bands.read more

Star-shaped π-conjugated oligomers and their applications in organic electronics and photonics
TL;DR: These structures are monodisperse, well-defined, discrete molecules with 100% synthetic reproducibility, and possess high purity and excellent solubility in common organic solvents and are therefore extremely attractive alternatives to conjugated polymers.
