摘　　要：We present a study of spectroscopic identification towards the molecular aggregates of zinc tetraphenylporphyrin （ZnTPP） illustrating how the energy states and intermolecular interactions determine the tunable properties of functional materials in condensation processes. Distinguishable fingerprints of ZnTPP nanorods and nanosheets are addressed utilizing X-ray diffraction （XRD）, Raman and UV-vis absorption spectroscopies. Although these ZnTPPs are assigned to J-aggregation at different extent, the spectral analysis reveals a significant role of the intermolecular interactions associated with varying mesoscale architectures. Energy decomposition analysis （EDA） revealed that the varied ZnTPP aggregates are stabilized by altered dispersion interactions due to the dominant ~r...zr stacking between the monomers.We present a study of spectroscopic identification towards the molecular aggregates of zinc tetraphenylporphyrin （ZnTPP） illustrating how the energy states and intermolecular interactions determine the tunable properties of functional materials in condensation processes.
