A simple colorimetric and ratiometric fluorescent anion sensor 1, 3,6-dichloro-1,8-dinitrocarbazole, was rationally designed and synthesized on basis of the mechanism of intramolecular charge transfer (ICT). In DMSO solutions of 1, the presence of AcO(-), F(-) and H(2)PO(4)(-) gave birth to the formation of a 2:1 host-to-guest complex, which was synchronously accompanied by a 'naked-eye' color change from light yellow to purple, a red-shift of the absorption spectrum and a blue-shift of the emission spectrum.
基于分子内电荷转移（ICT）机制，合理设计并合成了一种简单的比色和比率荧光阴离子传感器1,3,6 - 二氯 - 1,8 - 二硝基咔唑。在1的二甲基亚砜溶液中，AcO(-)、F(-)和H(2)PO(4)(-)的存在导致形成2:1的主客体复合物，同时伴随着“肉眼可见”的颜色从浅黄色变为紫色、吸收光谱的红移和发射光谱的蓝移。
