The use of organic conjugated polymers in sensors has attracted greater attention due to their application in materials technology. In the present communication, we utilized Schiff's condensation polymerization reaction for the synthesis of a novel conjugated polymer poly(tetrahexadecyl-dihydroindacenodithiophene)-alt-(p-phenylenediimine) (PIDTPD) consisting of indacenodithiophene (IDT) and p-phenylene diamine (PDA) units for use in acid vapor sensing. Conventionally, the characteristics and applications of conjugated polymers are affected by their constituents. The imine bond between the components of organic materials has received little attention compared to their active counterparts. In order to explore the practical application of conjugated polymers in sensors, we employed PIDTPD in a paper sensor and illustrated the impact of mono- and bis-protonation on the pristine material in driving a noteworthy protonation-induced color shift toward the longer wavelength region via acidochromism.

由于其在材料技术中的应用，有机共轭聚合物在传感器中的使用引起了人们的更多关注。在当前的交流中，我们利用席夫氏缩聚反应合成了由茚并二噻吩（IDT）和p组成的新型共轭聚合物聚（四十六烷基-二氢茚并二噻吩）-alt-（对苯二胺）（PIDTPD）。-苯二胺（PDA）单元，用于酸蒸气感测。常规地，共轭聚合物的特性和应用受其成分影响。与它们的活性对应物相比，有机材料各组分之间的亚胺键很少受到关注。为了探索共轭聚合物在传感器中的实际应用，我们在纸张传感器中使用了PIDTPD，并说明了单质子化和双质子化对原始材料的影响，该质子驱动质子化引起的色移向更长的波长区域通过。酸性变色。
