Multi-Responsive Materials


1) 三取代的硼烷具有显著的路易斯酸性,可与含有氧,氮等元素的基团形成路易斯酸碱对,从而影响含硼分子的光电性质。温度,机械力等外界刺激均可影响路易斯酸碱对的形成,因此这类化合物具有对外界刺激的响应性,有望成为功能材料的构筑单元


Stimuli responsive molecules is important building block for functional materials, and has attacted numerous attention recently. Our group is conducting several research projects in the area of temperature sensitive, mechano sensitive and photo sensitive materials based on unique property of boron containing organic molecules.

1) The trisubstituted borane has a remarkable Lewis acidity and can form a Lewis acid-base pair with a group containing an element such as oxygen, nitrogen, etc., thereby affecting the photoelectric properties of the boron-containing molecule. External stimuli such as temperature and mechanical force can affect the formation of Lewis acid-base pairs. Therefore, these compounds have responsiveness to external stimuli and are expected to become building blocks for functional materials.

2)Photo-responsive materials is a hot spot in recent years. Our research group found that tetra-substituted boron compounds with C-N chelate structure tend to have good photoisomerization properties and are expected to be the building blocks of new functional materials.

Luminescent Materials as Chemical Sensors

荧光和磷光化合物作为化学传感器具有巨大的潜力,因为它们可以对分析物提供灵敏且高选择性的可视化响应。 本组中该领域的研究工作目前主要集中在:




Fluorescent and phosphorescent compounds have great potential as chemical sensors, as they can provide a sensitive and selective response to an analyte that is observable to the eye. Research effort in the our group in this area is currently directed towards:

1) the development of luminescent triarylboranes for the selective detection of fluoride ions;

2) the preparation of transition metal containing luminescent solids for the detection of oxygen.

Projects in this area involve organic and organometallic synthesis, as well as characterization of the response of new materials to the analytes of interest.

Fluorescent Materials for OLED Applicaiton

有机荧光,磷光分子是有机发光二极管(OLED)的重要组成部分。近些年来,随着OLED和PLED等器件的商品化,市场对新型发光材料的需求也越来越高,因此可用与OLED的有机发光分子具有基础研究和实际应用双重意义。本课题组基于有机硼化合物优良的发光性质,在结构中引入推电子基团如三苯胺,咔唑等,形成具有D-A体系的有机发光分子。通过改变D A之间的结构关系,可以制得具有显著TADF性质的荧光分子,有望成为构筑新型OLED器件的发光材料。

Organic fluorescence, phosphorescent molecules are an important part of organic light-emitting diodes (OLEDs). In recent years, with the commercialization of devices such as OLEDs and PLEDs, the market demand for new luminescent materials is also increasing. Therefore, organic light-emitting molecules with OLEDs can be used for basic research and practical application. Based on the excellent luminescent properties of organoboron compounds, our group introduced electron-donating groups such as triphenylamine and carbazole into the structure to form organic luminescent molecules with D-A system. By changing the structural relationship between Donor and Acceptor, fluorescent molecules with significant TADF properties can be obtained, which is expected to be a luminescent material for constructing novel OLED devices.
