Problems solved by technology

However, since most organic crystals are centrosymmetric, bulk materials have no second harmonic response, limiting their application in practical processes
Therefore, obtaining low-dimensional organic frequency-doubling crystals with high conversion efficiency and easy preparation has become a new challenge.

Embodiment 1

[0041] Example 1. Controllable synthesis of low-dimensional organic frequency-doubling crystals with different structures

[0042] 0.1 mmol of p-nitroaniline and 0.1 mmol of β-cyclodextrin were sonicated into 20 ml of water to form a stable aqueous solution. The aqueous solution was vigorously stirred overnight to form an aqueous inclusion complex aqueous solution with a molar ratio of p-nitroaniline and β-cyclodextrin of 1:1. Then take out 20 microliters of the inclusion complex solution and drop it on the monocrystalline silicon substrate, put the monocrystalline silicon substrate into a beaker containing 3 milliliters of anti-solvent ethanol and seal it. To stabilize the growth of low-dimensional organic crystal materials, let the aqueous solvent evaporate slowly at room temperature for 2-3 days. The obtained low-dimensional organic crystal material was dried in a vacuum oven at 60°C for 4 hours to remove the remaining solvent, and used for future nonlinear optical tests. ...

[0047] 0.1 mmol of p-nitroaniline and 0.1 mmol of γ-cyclodextrin were sonicated into 20 ml of water to form a stable aqueous solution. The aqueous solution was vigorously stirred overnight to form an aqueous inclusion complex aqueous solution with a molar ratio of p-nitroaniline and γ-cyclodextrin of 1:1. Then take out 20 microliters of the inclusion complex solution and drop it on the monocrystalline silicon substrate, put the monocrystalline silicon substrate into a beaker containing 3 milliliters of anti-solvent ethanol and seal it.

Embodiment 3

[0051] Example 3. Test of second-order nonlinear optical properties of a single low-dimensional organic frequency-doubling crystal

[0052] For organic molecules with nonlinear optical properties, since they aggregate and assemble into centrosymmetric crystal structures, their crystal materials have no second harmonic response. By selecting suitable host molecules, the non-centrosymmetric arrangement of guest molecules can be induced using the strategy of host-guest inclusion coordination self-assembly. At the same time, choosing different anti-solvent systems can induce guest molecules to aggregate into low-dimensional organic frequency-doubling crystals with different structures. These low-dimensional organic frequency-doubling crystal materials have strong second harmonic response. image 3 Schematic diagram of the principle of second harmonic generation for low-dimensional organic crystals.

Abstract

The invention discloses a simple construction method of a low-dimensional organic frequency-doubling crystal; a host-guest inclusion coordination self-assembly strategy is utilized, guest molecules are induced to be arranged in a non-centrosymmetric structure, and inclusion complex molecules are aggregated to form the low-dimensional organic frequency-doubling crystal by an anti-solvent diffusion method. The construction method particularly comprises three steps: synthesis of the inclusion complex; controllable synthesis of the low-dimensional organic crystal material, and characterization of second-order nonlinear optical properties of the low-dimensional organic crystal material. The construction method provided by the invention is simple in process, convenient to operate, and friendly to the environment, and has universality on synthesis of similar low-dimensional organic frequency-doubling crystals. The construction strategy can greatly broaden the material selection range of the second-order nonlinear optical material. The material is expected to be used as a micro / nano light source device in an integrated nano photonic circuit.

Description

technical field [0001] The invention relates to a construction method of a low-dimensional organic frequency doubling crystal. Background technique [0002] Photonics is to explore the various functions and applications of photons as energy and information carriers on the basis of studying the interaction between photons and materials. In the 21st century, with the development of large-capacity and high-speed information processing such as optical communication and optical computing, the storage density required in information transmission is increasing, and the processing speed is getting faster and faster, which requires the size of unit devices to be as small as submicron or even nanometer class. In order to achieve the above goals, a new discipline—nanophotonics has been proposed. In the field of nanophotonics, a crucial challenge is to develop a coherent laser emission source. Nonlinear optics is a new branch of optics that develops rapidly after the appearance of la...
