A new class of organoboron compounds containing a boryl and an amino group at the o,o'-positions of biphenyls display bright through-space intramolecular charge transfer fluorescence owing to the close contact between the boryl and the amino groups. Binding of the fluoride ions results in the remarkable blue shift and color change of the fluorescence, enabling colorimetric and ratiometric fluoride ion sensing.
一类新型的有机硼化合物，其联苯的邻位,o,o'-位上分别含有一个硼基和一个氨基，由于硼基和氨基的紧密接触，这类化合物表现出明亮的通过空间分子内电荷转移荧光。氟离子的结合导致荧光显著蓝移和颜色变化，从而实现比色和比率型氟离子传感。
