The family of conjugated polymers known as polydiacetylenes (PDAs) has been extensively utilized in designing stimuli-responsive colorimetric and fluorometric sensors. In the current study, we have developed highly sensitive and rapidly responsive colorimetric chemosensors composed of PDAs bearing imidazole (PDA-Im) and triazole (PDA-Ta) head groups for the determination of pH and the detection of HCl gas. In solution, PDA-Im and PDA-Ta display distinct colorimetric changes from blue to red accordingly in response to pH changes. Also, a PDA-Im film was fabricated to detect HCl by a visibly observed blue-to-red color change.

含咪唑和三唑头基的聚二乙炔，用于比色监测pH和检测HCl气体†

被称为聚二乙炔（PDA）的共轭聚合物家族已被广泛用于设计刺激响应的比色和荧光传感器。在当前的研究中，我们已经开发了由具有咪唑（PDA-Im）和三唑（PDA-Ta）头基的PDA组成的高度灵敏和快速响应的比色化学传感器，用于测定pH和检测HCl气体。在溶液中，PDA-Im和PDA-Ta响应于pH值变化而显示出从蓝色到红色的明显比色变化。另外，制造了PDA-Im膜以通过可见的蓝到红颜色变化来检测HCl。
