Abstract
Nanostructured molecular assembly provides, in many cases, peculiar properties that are not found in the individual constituents. Among three-dimensional arrangements the tubular structures are particularly appealing for chemical sensor applications for expected surface increase and cavity effects. In this paper, the sensing properties of self-assembled nanotubes of oppositely charged porphyrins are investigated by measuring the changes of their optical properties. Computer screen photoassisted technology (CSPT) is utilized as a simple and practice platform to test the optical sensitivity of sensing materials and to develop chemical sensing systems. © 2007 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
