Problems solved by technology

[0003] But currently anti-B 18 h 22 There are relatively few studies on the derivatives of borane. In the early borane chemistry, some metal elements (nickel, platinum, cobalt, etc.) and non-metal elements (carbon, nitrogen, sulfur, oxygen) etc. have been used to modify octadecaborane. Molecular structure to prepare novel anti-B 18 h 22 Derivatives of anti-B in borane chemistry 18 h 22 There are very few studies on the aggregation-induced luminescent properties of the derivatives

preparation example Construction

[0029] The preparation method of the above trans-octadecaborane derivative. The preparation route is:

[0030]

[0031] The specific preparation process includes the following steps: 1) The isoquinoline and trans-octadecaborane are reacted in a solvent to obtain isoquinoline-substituted anti-B 18 H 22 Crude compound; 2) anti-B substituted with isoquinoline 18 H 22 The crude compound is obtained after purification.

Embodiment 1

[0033] This embodiment provides a preparation method of trans-octadecaborane derivative, which specifically includes the following steps:

[0034] 1) Add isoquinoline (0.505ml, 4.297mmol) dropwise to 20ml of dry benzene solution, and stir on a magnetic stirrer for 10min to disperse evenly, record it as solution A; then add the weighed trans 18 Anti-B 18 H 22 (200mg, 0.923mmol) into a 100ml round bottom flask, and add 60ml of dry benzene solution, and stir on a magnetic stirrer for about 15 minutes to anti-B 18 H 22 Completely dissolve, record it as solution B; add solution A slowly to solution B, the solution immediately turns yellow, and with the increase of solution A, the yellow color continues to deepen to orange-yellow, mark the mixture of A and B as C Solution: Heat and stir C solution under the protection of nitrogen atmosphere to make the benzene solution reflux. During this process, a yellow precipitate is formed, reflux for 10 hours and stop heating.

[0035] 2) After the...

Embodiment 2

[0042] This embodiment provides a method for preparing trans-octadecaborane derivatives. The difference from Example 1 is that: isoquinoline and trans-octadecaborane are directly put into a dry benzene solution in sequence, Heat and stir the C solution under protection to make the benzene solution reflux. Other conditions are the same as in Example 1. Finally, the reaction time of step 1) is prolonged by at least 2 times.

Abstract

The invention provides a trans-octadecaborane derivative as well as a preparation method and application thereof. The chemical formula of the derivative is B18C18H34N2, the molecular formula is B18H20(NC9H7)2, and the structural formula of the derivative is shown in the specification. The route of the preparation method is as follows: isoquinoline and trans-octadecaborane are used as raw materialsto synthesize an isoquinoline substituted anti-B18H22 organic borane derivative, and the structure, the absorption characteristic and the fluorescence characteristic of the isoquinoline substituted anti-B18H22 organic borane derivative are analyzed to find that the isoquinoline substituted anti-B18H22 organic borane derivative has an excellent aggregation-induced emission characteristic.

Description

Technical field [0001] The invention relates to the technical field of luminescent materials, in particular to a trans-octadecaborane derivative and a preparation method and application thereof. Background technique [0002] At present, traditional commercial blue laser materials are mostly organic materials such as laser dyes, conjugated polymers and oligomers, as well as materials based on inorganic colloidal quantum dots (DQs), which are not only expensive, but have low solubility and optical stability. low. As a new type of borane fluorescent material with blue fluorescence, transoctadecaborane breaks the traditional solution-treated blue laser gain material due to its good light stability, high quantum yield, and light controllability. (Such as organic compounds and semiconductor nanocrystals, etc.) in terms of solubility, chemical stability, light stability, and high price, it is expected to be applied to blue laser gain materials. So far, although some results have been ...
