The energetics of silver alkanethiolates with various long-chain lengths, formed through stepwise hierarchical assembly involving primary directional interactions between Ag and S forming the inorganic core and secondary stacking facilitating the formation of the three-dimensional structure, were directly assessed by in situ synthesis calorimetry. The thermal evolution of the materials is discussed in terms of confinement and synergy between enthalpy and entropy factors.
