preparation example Construction

[0040] Wherein, the preparation method of the semiconductor layer includes the steps of dissolving the natural blue pigment in the solution, and coating the solution on the substrate by spin coating or blade coating to form the semiconductor layer. The thickness of the semiconductor layer is 10 to 300 nm. Preferably, the thickness of the semiconductor layer is 20-80 nm.

[0041]In the present invention, the preparation of natural blue pigment refers to the patent application number CN201210416265.0 "Synthetic method and extraction process of blue natural dye". Grow in LB broth (10 g / L tryptone, 5 g / L yeast extract and 10 g / L sodium chloride) at 37°C with shaking at 250 rpm. After the OD600 of the culture reached 0.4˜0.6, 200 μM IPTG was added to induce the expression of Sc-IndC (indigo structure synthetase) and subsequent production of natural blue pigment. The induced broth was maintained for another 36 hours at 18°C ​​and 250 rpm. The natural blue pigment is then harveste...

[0045] In the present invention, the film used for optical measurement, cyclic voltammetry (CV) measurement and organic field effect transistor (OFET) characterization is to adopt organic evaporation system (Vaksis R&D and Engineering) to manufacture by physical vapor deposition, so as to realize the thickness precise control. Sublimation treatment is at 230-250°C, 10 -6 Under ultra-high vacuum conditions in the ceramic crucible (Al 2 o 3 ) is carried out below. Prior to deposition, the crucible was preheated to 230 °C with a closed substrate baff...

Embodiment 2

[0046] Embodiment 2 Spectral detection

[0047] The material was analyzed by ultraviolet-visible light spectrum and fluorescence spectrum, 0.006mM, 0.02mM, 0.6mM and 0.9mM dimethyl sulfoxide solutions of natural blue pigment were prepared respectively, and the molar extinction coefficient was determined by Beer-Lambert method.

[0048] The new material measures the absorbance of ultraviolet and visible light in a certain frequency range, so as to obtain the basic data of its optical properties, such as Figure 2A . As long as the organic compound is excited by ultraviolet or visible light, the electronic energy change can be determined by absorbance measurement. The optical gap is determined by Tauc plot, as Figure 2B , through the energy distribution of monochromatic light, a linear absorption feature can be observed. Natural cyanine is a natural compound, so under its optical gap reference, the optical absorption should be cut off at around 1.7eV.

Description

technical field [0001] The invention relates to the field of semiconductors, in particular to the application of a natural blue pigment in organic semiconductor devices. Background technique [0002] In the past few decades, semiconducting organic materials have attracted special interest due to their flexibility, ease of processing, low fabrication cost, and large area fabrication. Although organic semiconductors are considered more "green" compared to traditional inorganic semiconductors due to their low processing temperature, ease of handling (e.g. and deposition techniques still require the use of toxic halogenated solvents. Biosynthetic methods offer particular advantages over traditional chemical synthesis; enzymes, used in biosynthesis, typically operate in "biofriendly" environments—aqueous media, room temperature, neutral pH, and atmospheric conditions . In general, biosynthetic methods can obtain complex molecules from inexpensive and abundant materials. [00...
