Improving the properties of VTP by incorporating fullerene

Abstract

In this study, fabrication of vanadyl 3,10,17,24-tetra-tert-butyl-1,8,15,22-tetrakis(dimethylamino)-29H,31H-phthalocyanine (VTP):[6,6]-phenyl C₇₁ butyric acid methyl ester (PC₇₁BM) composite nanotubes is proven to be successful. VTP:PC₇₁BM composite nanotubes were fabricated via a layer-by-layer method with the assistance of a templating technique. Field emission scanning electron microscopy (FESEM) images have shown successful infiltration of the VTP solution and the further replication of the template with different morphological properties. Infiltration of PC₇₁BM and replication of VTP nanotubes have led to the improvement of morphological, optical and structural properties. Photo-absorption analysis via a UV-vis spectrometer has shown the remarkable absorption spectra of VTP nanotubes (p-type) as well as a further enhancement after the PC₇₁BM (n-type) is introduced into the pre-synthesized nanotubes. Significant red-shifts in the Q-band and B-band region of the VTP:PC₇₁BM composite nanotubes are observed with the incorporation of PC₇₁BM. Morphological analysis of composite nanotubes with different behavior of infiltration has proven influential towards the optical behavior as well as their structural properties.
