摘要
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.
