Molecular Weight Characterization of Conjugated Polymers Through Gel Permeation Chromatography and Static Light Scattering

Molecular weight is a key parameter of any polymer. Characterizing the molecular weight of conjugated polymers is often nontrivial due to their semiflexible backbones and poor solubilities. Perhaps the most used technique for measuring the molecular weight is gel permeation chromatography (GPC), and results are often calibrated relative to flexible polymer standards. This mismatch between chain flexibilities of samples and standards, combined...
