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-mentioned trans-octadecaborane derivatives. Its preparation route is:

[0030]

[0031] The specific preparation process includes the following steps: 1) react isoquinoline and trans-octadecaborane in a solvent to obtain isoquinoline-substituted anti-B 18 h 22 Compound crude product; 2) anti-B substituted with isoquinoline 18 h 22 The crude compound is purified and obtained.

Embodiment 1

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

[0034] 1) Add isoquinoline (0.505ml, 4.297mmol) dropwise into 20ml of dry benzene solution, and stir on a magnetic stirrer for 10min to disperse evenly, and record it as solution A; then weighed trans-18-boron alkane anti-B 18 h 22 (200mg, 0.923mmol) was poured into a 100ml round bottom flask, and 60ml of dry benzene solution was added, stirred on a magnetic stirrer for about 15min until anti-B 18 h 22 Completely dissolved, recorded as B solution; slowly drop A solution into B solution, the solution immediately turned yellow, and with the continuous increase of A solution, the yellow color continued to deepen to orange yellow, and the mixture of A and B was recorded as C Solution; under the protection of nitrogen atmosphere, heat and stir the C solution to reflux the benzene solution. During this process, a yellow precipitate is formed...

Embodiment 2

[0042] This embodiment provides a preparation method of trans-octadecaborane derivatives. The difference from Example 1 is that isoquinoline and trans-octadecaborane are directly put into the dry benzene solution in sequence, and Heating and stirring the C solution under protection makes the benzene solution reflux, and 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, a preparation method and application thereof. The chemical formula of the derivative is B 18 C 18 h 34 N 2 , the molecular formula is B 18 h 20 (NC9H 7 ) 2 , the structural formula is: the route of the preparation method is: the present invention uses isoquinoline and trans-octadecaborane as raw materials to synthesize isoquinoline substituted anti‑B 18 h 22 Organoborane-like derivatives have been found to have excellent aggregation-induced luminescent properties through the analysis of their structures, absorption properties and fluorescence properties.

Description

technical field [0001] The invention relates to the technical field of luminescent materials, in particular to a trans-octadecaborane derivative and its preparation method and application. Background technique [0002] At present, the traditional commercial blue laser materials are mostly organic materials such as laser dyes, conjugated polymers, oligomers, and materials based on inorganic colloidal quantum dots (DQs), which are not only expensive, but also have low solubility and relatively high optical stability. Low. As a new borane fluorescent material with blue fluorescence, trans-octadecaborane has broken the traditional solution-processed blue laser gain material due to its good photostability, high quantum yield, and light-tunable properties. (such as organic compounds and semiconductor nanocrystals, etc.) are limited in solubility, chemical stability, photostability, and expensive, and are expected to be applied to blue laser gain materials. So far, although the r...
