New aza-BODIPY indicators which cover the pH scale from 1.5 to 13 are presented. The new indicators feature absorption/emission bands in the red/near-infrared (NIR) spectral region, exhibit high molar absorption coefficients (∼ 80,000 M(-1) cm(-1)) and show good quantum yields (∼20%). All dyes represent promising building blocks for the development of a broad-range sensor for various pH ranges. Combination of four of these pH indicators yields a pH sensor with an extended dynamic range from pH 2 to 9.
本文介绍了一系列新型氮杂硼二吡咯（aza-BODIPY）指示剂，其适用的pH范围为1.5至13。这些新型指示剂在红色/近红外（NIR）光谱区域具有吸收/发射带，具有高摩尔吸收系数（约80,000 M⁻¹ cm⁻¹），并且显示出良好的量子产率（约20%）。所有染料都是开发适用于各种pH范围的宽范围传感器的有前景的构建模块。将其中四种pH指示剂组合可得到一种pH传感器，其动态范围扩展至pH 2至9。
