Triphenylamine (TPA) derivatives and their radical cation counterparts have successfully demonstrated a great potential for applications in a wide range of fields including organic redox catalysis,organic semi-conductors,magnetic materials,etc.,mainly because of their excellent redox activity.The stability of TPA radical cation has significant effect on the properties of the TPA-based functional materials,especially in relation to their electronic properties.Considering the instability of parent TPA radical cation,many ef-forts have been devoted to the development of stable TPA radical cations and related materials.Among them,TPA radical cation-based macrocycles have attracted particular attention because their large de-localized structures can stabilize the TPA radicals,thus endow them with outstanding redox behaviors,multiple resonance structures,and wide application in various optoelectronic devices.In this review,we give a brief introduction of organic radicals and the documented stable TPA radicals.Subsequently,a number of TPA radical cation-based macrocycles are comprehensively surveyed.It is expected that this minireview will not only summarize the recent development of TPA radical cations and their macrocy-cles,but also shed new light on the prospect of the design of more sophisticated radical cation-based architectures and related materials.

通过一系列动三轴试验,研究了循环应力水平和围压对纤维加筋砂变形与刚度的影响,分析了不同围压和应力幅值条件下,纤维加筋砂的残余轴向应变、残余体积应变以及动态杨氏模量的动态响应规律.试验结果表明:随着循环应力水平的提高,残余轴向应变的发展呈现出塑性安定、塑性蠕变与塑性破坏3种不同的机制;应力幅值越大,残余轴向应变和残余体积应变增长越快;动态杨氏模量在小应变范围内保持恒定,一旦超过应变阈值,动态杨氏模量随着应变的增加而降低.

为研究粗骨料形状特性对粗骨料堆积状态的影响,利用PFC3 D5.0离散元分析软件,对不同级配、不同针片状含量的粗骨料进行了堆积模拟分析.将三维扫描获取的粗骨料外轮廓信息经过图像分析处理,构建仿真骨料数据库,并以此为基础完成粗骨料堆积模拟,计算堆积密实度.对比分析模拟计算结果与实验结果,二者具有较高的吻合度,说明该模拟分析方法的准确性及精度较高,不仅能对骨料进行粒形仿真构建,对骨料进行堆积模拟,而且能对级配、针片状含量对骨料堆积密实度的影响分析提供理论方法.
