Glass Transition Temperature from the Chemical Structure of Conjugated Polymers
The glass transition temperature (Tg) is a key property that dictates the applicability of conjugated polymers. The Tg demarks the transition into a brittle glassy state, making its accurate prediction for conjugated polymers crucial for the design of soft, stretchable, or ﬂexible electronics. We show that a single adjustable parameter can be used to build a relationship between the Tg and the molecular structure of 32 semiﬂexible (mostly conjugated) polymers that differ drastically in aromatic backbone and alkyl side chain chemistry.
