Embodiment approach
[0055] According to one embodiment of the present invention, the method for preparing cobalt phthalocyanine nanowires comprises the following steps:
[0056] a) introducing the cobalt phthalocyanine source into the heating zone in the tube furnace,
[0057] b) In the presence of carrier gas, heating and sublimating the cobalt phthalocyanine source material up to 500°C,
[0058] c) carrying the sublimed cobalt phthalocyanine to the growth area adjacent to the heating area by means of a carrier gas,
[0059] In the growth region, cobalt phthalocyanine molecules grow into nanowires, wherein the temperature of the growth region is lower than 200°C, preferably lower than 150°C, further preferably lower than 100°C, more preferably lower than 50°C, still more preferably room temperature.
[0060] According to one embodiment, the XRD diffraction spectrum of the cobalt phthalocyanine nanowires of the present invention has the following characteristic peaks:

Embodiment 1
[0064] After cleaning the quartz tube and the quartz substrate in turn, and connecting and installing the experimental equipment, adjust the experimental conditions as follows: the gas pipeline is PU1065 hose, the pressure in the quartz tube cavity is normal pressure, and the carrier gas is N 2 , using a split-type tube furnace with independent temperature control in three temperature sections. The cobalt phthalocyanine source material is placed in the central position of the high temperature section of the tube furnace, and the other two temperature sections are not heated. Regulation N 2 The flow rate at the inlet is 0.4L / min. Pass N for a while before heating 2 , and then heat the cobalt phthalocyanine source material, first heating the cobalt phthalocyanine source material to 400°C, then stepping up the temperature to 450°C at a rate of 1-5°C / min, reaching 450°C and keeping it warm for 190 minutes. The carrier gas guides the cobalt phthalocyanine sublimation gas through...
Embodiment 2
[0067] On the basis of Example 1, the experimental conditions were changed: a programmable temperature-controlled single-temperature section open-type tube furnace was used, and the temperature was raised to 450 ° C in the above-mentioned heating method, and the temperature was kept for 220 minutes. The carrier gas guided the cobalt phthalocyanine sublimation gas to the The heating zone is adjacent to the growth zone. The growth zone and the heating zone pass through a 100mm quartz gap. A plurality of holes with a diameter of 5 mm are provided in the quartz interstitial region. After passing through the spacer, the flow rate of the carrier gas was increased to 3 L / min. After the heating, the ventilation was continued for 30 minutes, and then the ventilation was stopped, and the cobalt phthalocyanine nanowires were grown in the growth area at 50°C. Collect J-CoPc nanowires.
[0068] The cobalt phthalocyanine nanowire that obtains is tested using the XRD testing instrument (t...
