Polymorphism of a semi‐crystalline diketopyrrolopyrrole‐terthiophene polymer [PDF]
Journal of Polymer Science, 2020 AbstractFew semiconducting polymers are known that possess more than one semi‐crystalline structure. Guidelines for rationalizing or creating polymorphism in these materials do not exist. Two different semi‐crystalline polymorphs, β1 and β2, and an amorphous α phase have recently been identified for alternating diketopyrrolopyrrole‐quaterthiophene ...
