Embodiment 1

[0090] A method for synthesizing oligotriphenylene with controllable nanostructure, specifically comprising the following steps:

[0091] (1) Accurately weigh 115mg (0.5mmol) of triphenylene and dissolve in 50mL of dichloromethane to form a 0.01mol / L triphenylene monomer solution;

[0092] (2) According to the molar ratio of oxidant and triphenylene monomer of 20:1, weigh 1622 mg (10 mmol) of anhydrous ferric chloride and dissolve it in 75 mL of nitromethane to form an oxidant solution;

[0093] (3) After blending the oxidizing agent solution and the monomer solution, shake it violently for a while and then vibrate ultrasonically for 30 minutes, then place it in a water bath at a constant temperature, and react with magnetic stirring for 48 hours to obtain oligotriphenylene with a controllable nanostructure Crude reaction solution;

[0094] (4) After taking out the reaction liquid, control the rotation speed to 3000~4500r / min, centrifuge and settle for 30~60 minutes to obtain...

Embodiment 2

[0109] A method for synthesizing oligotriphenylene with controllable nanostructure, specifically comprising the following steps:

[0110] Chlorobenzene was used instead of dichloromethane, and the others were the same as in Example 1, and brown powdery oligotriphenylene with controllable nanostructure was finally obtained.

Embodiment 3

[0112] A method for synthesizing oligotriphenylene with controllable nanostructure, specifically comprising the following steps:

[0113] Nitrobenzene was substituted for dichloromethane, and the others were the same as in Example 1, finally obtaining a brown powdery oligotriphenylene with a controllable nanostructure.

[0114] The nano-morphology of the oligomerized triphenylene obtained in the above-mentioned embodiment 1, embodiment 2 and embodiment 3 is shown in Figure 6 , Figure 7 and Figure 8 . When dichloromethane, chlorobenzene and nitrobenzene are used as solvents for triphenanthrene monomers, the diameters of the obtained oligomerized triphenanthrene nanofibers are 50 nm, 80 nm and 120 nm, respectively. The use of dichloromethane as a solvent enables relatively small diameters to be formed.

Abstract

The invention discloses a nano-structure controllable oligomerized benzophenanthrene and a synthesis method thereof. The synthesis method comprises the following steps: dissolving benzophenanthrene monomer in a first solvent to form a monomer solution; dissolving oxidant anhydrous ferric chloride in a second solvent to form an oxidant solution; and evenly mixing the monomer solution and the oxidant solution, reacting under the action of ultrasonic vibration for 30 minutes, and continuing reacting under the action of magnetic stirring for 48 hours to obtain the nano-structure controllable oligomerized benzophenanthrene. The diameter and length of the nano fiber are respectively 50-300nm and 1-5 mu m, and the fluorescence intensity and fluorescence quantum efficiency are respectively 7.2 times and 5.2 times of the monomer. The invention has the advantages of simple synthesis steps, high efficiency and high controllability, and the yield of the synthesized oligomerization benzophenanthrene is up to 72%.

Description

technical field [0001] The invention belongs to the technical field of preparation of organic photoelectric conjugated molecular nanomaterials, and in particular relates to an oligomerized triphenylene with controllable nanostructure and a synthesis method thereof. Background technique [0002] Triphenylene (Triphenylene, TP), also known as triphenylene, is a planar polycyclic aromatic hydrocarbon composed of four benzene rings condensed, and its chemical formula is C 18 h 12 , with a molecular weight of 228.29 g / mol, and its chemical structure is shown below. Triphenylene is a polycyclic aromatic hydrocarbon with an all-benzene structure. Its structure can be seen as four carbon-carbon single bonds connecting three benzene rings in sequence. It consists of four triphenylene molecules and has eighteen Planar structures of delocalized π electrons. [0003] [0004] The chemical structure of triphenylene monomer [0005] Triphenylene and its derivatives have become o...
