  摘要：

  合成了与3'-羟甲基-4-(二甲氨基)偶氮苯结构相关的20种偶氮苯衍生物，旨在研究其诱变和致癌效应。它们是3'-甲基-DAB的氧化产物、对称取代的偶氮化合物、它们的乙酰或氯衍生物及其异构体。4-(二甲氨基)偶氮苯是通过相应的重氮盐与N,N-二甲基苯胺反应制备的，而偶氮苯则通过相应的硝基苯在氢氧化钠介质中用氢化铝锂或锌还原得到。给出了这些化合物的物理特性（熔点、元素分析、红外、紫外和质谱数据）。

  The present teaching provides a fluorescent oligonucleotide probe having a high degree of design flexibility and wide applicability, as well as the use thereof. This is an oligonucleotide probe capable of forming a stem and loop, comprising at least one fluorophore located between adjacent nucleotides in the stem and is linked to a unit represented by Formula (1) and at least one quencher located at a site capable of pairing up with the at least one fluorophore located between the adjacent nucleotides in the stem and is linked to a unit represented by Formula (2). (In the formulae, X represents the fluorophore, Y represents the quencher, R1 represents an optionally substituted C 2 or C 3 alkylene chain, R2 represents an optionally substituted C 0-2 alkylene chain, and Z represents a direct bond or linker.)

  Novel thermochromic and/or photochromic compositions are described. The thermochromic compositions include a thermoset resin, cholesterol, water, and dye, while photochromic compositions include a benzene and a binder, such as silica gel. When mixed, the ingredients of the thermochromic and photochromic compositions form chromic cells with an outer shell comprised of either the thermoset resin (in the case of thermochromic compositions) or potassium nitrate (in the case of photochromic compositions). When the chromic compositions are exposed to either a heat or light stimulus, the chromic cells compress to causing the dye within the cells to no longer be visible, thereby creating a color-changing effect.

  本文描述了新型热致变色和/或光致变色组合物。热致变色组合物包括热固性树脂、胆固醇、水和染料，而光致变色组合物包括苯和粘合剂，如硅胶。热致变色组合物和光致变色组合物的成分混合后会形成铬电池，其外壳由热固性树脂（热致变色组合物）或硝酸钾（光致变色组合物）组成。当色素组合物受到热或光的刺激时，色素细胞会压缩，使细胞内的染料不再可见，从而产生变色效果。
