  Dibenzoborole-Containing π-Electron Systems:  Remarkable Fluorescence Change Based on the “On/Off” Control of the p_π−π* Conjugation

  摘要：

  A series of dibenzoborole derivatives with various groups such as (N,N-diphenylamino)phenyl, thienyl, and bithienyl groups at the 3,7-positions have been synthesized and their photophysical properties studied. These new pi-electron systems show significant solvatochromism in the fluorescence spectra. Thus, about 100-140 nm blue shifts in the emission maxima and 20-30-fold increments in the quantum yields are observed upon changing the solvent from THF to DMF. Similar fluorescence changes are observed upon the addition of n-Bu4NF to their THF solutions, demonstrating their sensing abilities toward a fluoride ion. These fluorescence changes result from the "on/off" control of the ppi-pi* conjugation in their LUMO by the coordination of donor solvents or fluoride ion to the boron atom in the dibenzoborole skeleton.

  Various types of main group element-containing π-electron systems have been synthesized using silole, dibenzoborole, or bis-silicon-bridged stilbene as the key building units. In these π-electron systems, the orbital interaction between the main group element moiety and the π-conjugated framework, such as p π -π* and σ*-π* conjugation, plays a crucial role in determining their characteristic electronic

  已经使用silole、dibenzoborole或bis-silicon-bridged stilbene作为关键构建单元合成了各种类型的含主族元素的π-电子系统。在这些 π 电子系统中，主族元素部分与 π 共轭骨架之间的轨道相互作用，如 p π -π* 和 σ*-π* 共轭，在决定它们的特征电子结构方面起着至关重要的作用，并使得它们是用于有机电子和光电子应用的有前途的材料。
