摘　　要：针对有机光致变色材料应用中存在的抗疲劳性差、记录信息在读取后遭到破坏等问题,设计并合成了4-(3-吡啶基偶氮)苯酚与钴四苯基卟啉轴向配合物。光致变色研究结果表明,该配合物在365 nm的紫外光和515 nm的可见光交替照射下可发生可逆的光致变色反应,且重复光照多次后展示出良好的抗疲劳性。在415 nm激发光波长的作用下,化合物中4-(3-吡啶基偶氮)苯酚转变为顺式结构时比反式结构具有较高的荧光强度,2种状态下明显的荧光对比度可实现数据的无损读取功能。Organic photochromic materials have problems in practical application,such as poor fatigue resistance and the destruction of recorded information after read-out.Herein,the axial complex between 4-(3-pyridylazo)phenol and cobalt tetraporphyrin is designed and synthesized.It is indicated from photochromic research that this axial complex possesses good photochromic conversion behavior and fatigue resistance upon alternating irradiation with 365 nm UV light and 515 nm visible light.It has a prominent fluorescence contrast under the light(λ=415 nm)during the transformation of cis to trans states,which can realize the nondestructive readout in the field of data writing and reading.
