Irreversible transformation of the porphyrin supramolecular structures under a water vapor environment

Supramolecular structures formed by H4TPPS42-have been widely used for different applications.In this paper,the stability of H4TPPS42- nanorods on mica substrate is investigated by atom force microscopy （AFM） observation.An irreversible transformation of H4TPPS42-from nanorods （3.8±0.4 nm in height）...

Description
Summary:Supramolecular structures formed by H4TPPS42-have been widely used for different applications.In this paper,the stability of H4TPPS42- nanorods on mica substrate is investigated by atom force microscopy （AFM） observation.An irreversible transformation of H4TPPS42-from nanorods （3.8±0.4 nm in height） to a lower film structure （1.9±0.4 nm in height） was found with the samples incubated at various relative humidities （RH）.The transformation rate depends strongly on the RH and environment temperature.
