It was found that nanowire-like structures can be prepared when it is anodized in an electrolyte containing F-ions under appropriate conditions and the anodically prepared nanowire-like structure consisted of ZnF2.
When carried out at 40 V, nano-porous structure appears and covers the zinc foil, as shown in Fig. 5a.
Thermal oxidation of solid Zn nanostructure to produce good quality/structure ZnO has been adopted in the literature [15, 16].
As shown in Figs.6a&b, the hexagonal micro-pores structured Zn was converted to hexagonal micro-pores structured ZnO with nanowire-like ZnO grown on the wall surfaces.

Porphyrins and metalloporphyrins are field-responsive materials [3] that can be considered as a building block in producing charge-transporting layer in an OFET because of their large size, ease of synthesis, thermal stability and diversity of their coordination and catalytic chemistry [4].
Knowledge about the relationship between molecular structure, crystal packing and device performance remains great challenges for researchers to explore [7].
