“…Despite of having highest light absorption, template with no stirring process has shown the blue-shifting at 354, 677, and 715 nm when infiltrated with VOPcPhO. This observation has proven that VOPcPhO that have been infiltrated into the various pores size (10 -100 nm) will halt the π-π* transition 28 . Postulation on the dependency between photon absorption, π-π* transition and architecture of template can be rather acceptable.…”

In this study, the fabrication of in-situ anodic alumina template (AAO) directly onto glass substrate is realized by varying the stirring speeds and molarity of phosphoric acid. Porous alumina template will then be used to infiltrate vanadyl 2, 9, 16, 23-tetraphenoxy-29H, 31H-phthalocyanine (VOPcPhO) prior to the formation of alumina:VOPcPhO nanocomposite. VOPcPhO has seen to fully infiltrate the template with the excess formation of VOPcPhO layer on top of the porous due to the lengthy immersion time of 6 hours. Uniformity and density of pore size, and available pore, can be respectively tuned by varying the stirring speeds (0 -300 rpm) and molarity of pore widening agent (0 -10 % of phosphoric acid). Roundedsphere shape of pores has been observed with higher transparency template is dominated by stirring the speed between 100 and 200 rpm. At these speeds, the template's pore size and pore density are highly homogeneous. Different molarity of phosphoric acid as a pore widening agent has an effect on the pore size and pore density. Occurrence of merging pores is observed by increasing the molarity of agent to 10% which unlikely to happen in the lower molarity of 5% phosphoric acid. Optical properties of alumina:VOPcPhO nanocomposites that identified from the characterization of UV-vis, photoluminescence (PL) and Raman spectroscopies, support the successful infiltration of VOPcPhO. Alumina:VOPcPhO nanocomposite has ability to absorb light at the longer wavelength and photon can be emitted by the nanocomposite at the respective energies.

“…As seen in UV-vis spectrum, the VOPcPhO has portrayed the significant peaks absorption between 300 and 750 nm. The peak absorption of VOPcPhO thin film is located at 348 nm which assigned as Soret band (B band) and at 677 and 713 nm of Q band [2][3][4]8,9,18]. UV-vis spectrum of VOPcPhO thin film portrayed an extensive valley between 400 and 600 nm which in the UV-vis spectrum of PC 71 BM thin film shows its main peak absorption positioned within this valley.…”

“…Metal phthalocyanine nanostructures such as nanotubes, nanoflowers, nanorods, nanowires, and nanoribbons [3][4][5][6] have shown the remarkable approaches and the emergence of versatile fabrication. A spin coating technique has been implemented in fabricating the electronic devices (such as sensors and solar cells) with the incorporation of metal phthalocyanine as bulk heterojunction structure [1,[7][8][9].…”

“…Among of numerous techniques used in fabricating the novel architecture of nanostructured materials, uncomplicated technique of template-assisted method is of considerable interest [3][4][5][10][11][12]. In contrast to the interpenetrating bulk heterojunction structure synthesized by blending the p-and n-type materials, template-assisted method of porous alumina could produce a versatile and unique heterostructured nanostructure such as composite nanorods and nanotubes by a simple layer-by-layer approach [4,13]. Via a simple layer-by-layer approach, two dissimilar materials are incorporated together at a different time.…”

“…It is considered as a macro-cyclic compound where its structure consists of four isoindole units surrounding the center metal atom. VOPcPhO also exhibits wide absorption in UV-vis spectral region between 300 and 750 nm [1][2][3][4][7][8][9]. In addition, metal phthalocyanine is capable to act as a sensitizer of photo-induced electron transfer to acceptors, which can be efficiently achieved by incorporating it with the fullerene groups such as [6,6]-phenyl C61 butyric acid methyl ester (PC 61 BM) and [6,6]-phenyl C71 butyric acid methyl ester (PC 71 BM) [15].…”

The use of templating method to synthesize the vanadyl 2,9,16,23-tetraphenoxy-29H,31H-phthalocyanine (VOPcPhO): [6,6]-phenyl C71 butyric acid methyl ester (PC 71 BM) composite nanotubes is presented here. VOPcPhO is a p-type material and PC 71 BM is an n-type material which acts as an electron donor and electron acceptor, respectively. Both materials have been studied due to their potential applications as solar energy converter and organic electronics. High-resolution transmission electron microscope (HRTEM) and field emission scanning electron microscope (FESEM) images have shown the replication of the porous template diameter of approximately 200 nm with a superior incorporation of both VOPcPhO and PC 71 BM. VOPcPhO:PC 71 BM composite nanotubes showed the significant properties improvement if compared over their bulk heterojunction counterpart. UV-vis spectra of composite nanotubes show a shift to a longer wavelength at the absorption peaks. Significant quenching has been attained by the photoluminescence spectra of VOPcPhO:PC 71 BM composite nanotubes which supports the redshift of UV-vis absorption spectra. Presumably, the photo-induced charge transfer and charge carrier dissociation can be enhanced from the VOPcPhO:PC 71 BM composite nanotubes rather than the bulk heterojunction.
