Counting Chromophores in Conjugated Polymers

Counting Chromophores in Conjugated Polymers

The emitting species in conjugated polymers have been studied by single‐molecule spectroscopy (see picture). The number of emissive centers (chromophores) varies as a function of molecular weight and chain length. A large ladder‐type undecaphenylene was used as a molecular ruler to estimate the size...

Beschreibung
Zusammenfassung:The emitting species in conjugated polymers have been studied by single‐molecule spectroscopy (see picture). The number of emissive centers (chromophores) varies as a function of molecular weight and chain length. A large ladder‐type undecaphenylene was used as a molecular ruler to estimate the size of chromophores in the polymer and to enable a direct assessment of the polymeric conjugation length.
