Achieving highly efficient aggregation-induced emission, reversible and irreversible photochromism by heavy halogen-regulated photophysics and D–A molecular pattern-controlled photochemistry of through-space conjugated luminogens

Highly efficient aggregation-induced emission, reversible and irreversible photochromism are achieved by regulating heavy halogen-regulated photophysics and D–A molecular pattern-controlled photochemistry of through-space conjugated luminogens.
