Ultrafast proton transfer reaction is a topic of great interest particularly due to their association with the understanding of primary and elementary reaction pathways in functional electrochemical and biological systems. Although this reaction has been extensively investigated in solution for the role of interaction between the solute and the solvent-bath, but the dynamics in single molecular crystals remains elusive. Here, we study ultrafast intramolecular proton transfer reaction in hydroxyanthraquinones in crystalline form, where molecular system forms lattice. We use ultrafast transient absorption studies complemented with quantum chemistry calculations to reveal the role of spatial arrangement of the reactants within the lattice in reaction dynamics. Our work highlight the importance of intermolecular interactions guiding ultrafast dynamics in crystals.
