title: Modifications of Structure and Intermolecular Potential of a Canonical Glassformer: Dynamics Changing with Dipole-Dipole Interaction.
abstract: By systematic modifications of the canonical propylene carbonate, a family of van der Waals glass-formers with similar chemical structures is generated for dielectric studies of the dynamics of the structural α-relaxation with the purpose of critically testing the correlation of dynamic properties with the dipole-dipole interaction contribution to the intermolecular potential. With the dielectric strengths at Tgvarying over a vast range from 4.2 to 182, the modified propylene carbonates provide strong support of the correlation by themselves and in conjunction with 88 van der Waals glassformers previously considered ( Phys. Rev. Lett. 2016 , 116 , 025702 ).
