exclusively formed the 8′ isomer. The same ratios were reproduced via photolytic experiments, which suggested that the condensation reaction is dominated by the product’s thermodynamic stability. The electronic influences of the substituents extends beyond isomer control, as it impacts the DHIs’ optical properties and electrocyclization (switching) rates to the spiro conformers. Our results allow us to predict
