Revealing Elusive Polymorphism in a Highly Luminescent β-Cyano-Substituted Distyrylbenzene Using MicroED

Year: 2026

Type: preprint

Abstract: The elusive dimorphic β-(outer) regioisomer of a cyano-substituted distyrylbenzene derivative (PDN-4) was characterized using MicroED. Despite having identical substituents to α-(inner) regioisomer, β-PDN-4 exhibits an exceptionally rare syn-rotamer alongside an anti-conformation, leading to distinct photophysical properties that are well supported by theoretical calculations.
