Abstract
Spontaneous deposition of aggregates of a tetraphenylporphyrin derivative, possessing a cationic chiral appended functionality, straightforwardly occurs from aqueous solutions. The thickness of the layers depends on the initial macrocycle concentration. Combined UV-Vis, and CD spectroscopy studies and AFM morphological characterisation reveal that these layered films feature a peculiar fractal-type morphology. This aspect can be of great importance for the construction of solid state chemical sensors featuring interesting stereoselective properties.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
