A novel 1D Cd(ii) based coordination polymer (complex 1) has been synthesized involving an 8-aminoquinoline based Schiff base ligand and cyanate ion. It has been characterized by elemental analysis, different spectroscopy methods and X-ray single crystal diffraction technique. Most interestingly it exhibits unique properties like electrical conductivity and photosensitivity which shows its potential in optoelectronic device application. We prove both experimentally and theoretically that electrical conduction under irradiation of visible light increases many fold in comparison with that under dark condition. Our synthesized material based device shows some paramount behaviour under irradiance of light which is obvious in light sensing Schottky devices. The rectification ratio of our complex based device was found to be 12.44 and 27.74 under dark and photoirradiation conditions respectively. The discovery of such type of coordination polymer advances the area of optoelectronic devices.
一种基于一维镉（II）的新型配位聚合物（配合物1）已通过一种基于8-氨基喹啉的席夫碱配体和氰酸根离子合成。它已通过元素分析、不同的光谱方法和X射线单晶衍射技术进行了表征。最有趣的是，它表现出独特的性质，如导电性和光敏性，这表明其在光电器件应用中的潜力。我们通过实验和理论证明，与黑暗条件下相比，可见光照射下的电导率增加了许多倍。我们合成材料制成的器件在光照下表现出一些至关重要的行为，这在光传感肖特基器件中很明显。我们基于配合物的器件在黑暗和光辐照条件下的整流比分别为12.44和27.74。这种类型配位聚合物的发现推动了光电器件领域的发展。
