Enhanced E → Z photoisomerisation in 2-aminoazobenzene†
Abstract
Theoretical non-adiabatic dynamics simulations at the semiempirical OM2/MRCI level reveal an enhanced E → Z photoisomerisation for 2-aminoazobenzene. The E isomer contains an intramolecular hydrogen bond which weakens the azo N–N bond and thus facilitates isomerisation.
