The photoreactive organic semiconductors have been studied a lot due to their interesting optical properties and can be grown in various forms depending on the manufacturing method.
1D crystalline organic microtubes have demonstrated excellent optical waveguide nature. the design and fabrication of 1D crystals exhibiting exotic functions remain a great challenge.
Herein we fabricate one-dimensional microtubes (1D-MTs) of organic semiconducting Alq3 fabricated by self-assembly methods in de-ionized (DI) water. The formation of tubular structure of the Alq3 is visually confirmed by a scanninig electron microscope and a high resolution transmission electron microscope. The optical and structural properties of the MTs are characterized using ultraviolet and visible absorption, Raman, and photoluminescence (PL) spectra where it is shown that the PL of the Alq3 materials is enhanced after the formation of tubular structures.
