Azobenzene is a popular choice among the chromophores. The thermodynamically favored trans isomer is rapidly converted to the cis isomer by irradiation at the wavelength of the π-π* transition, whereas the reverse process is achieved either (slowly) by thermal relaxation in the dark or () by irradiation at the wavelength of the n-π* transition. The azobenzene amino acid (aa) can be used as a photo-inducible conformational switch in polypeptides. A reversible conformational change of the peptide backbone is induced by switching between the cis and trans configurations of the azobenzene moiety by irradiation with light of suitable wavelength. Azobenzene has been the most widely used optical trigger for the synthesis of photoresponsive systems ranging from poly-a-amino acids to innovative materials with light-controlled mechanical and optical properties. Its use in form of appropriate derivatives allow to generate cyclic peptide structures of constraint conformational space and thus to exploit its reversible photoisomerization to induce well defined transitions between different conformational states. Azobenzene photoswitches can be used to drive functional changes in peptides, proteins, nucleic acids, lipids, and carbohydrates.危险品标志T - 有毒物品 N - 危害环境的物品 Xn - 有害物品 F - 易燃物品 风险术语R45 - 可能致癌。 R20/22 - 吸入及吞食有害。 R48/22 - 吞食长期接触严重危害健康。 R50/53 - 对水生生物有极高毒性，可能对水体环境产生长期不良影响。 R68 - 可能有不可逆后果的危险。 R67 - 蒸汽可能引起困倦和眩晕。 R65 - 吞食可能造成肺部损伤。 R62 - 有损害生育能力的危险。 R51/53 - 对水生生物有毒，可能对水体环境产生长期不良影响。 R38 - 刺激皮肤。 R11 - 高度易燃。 R48/20 - R39/23/24/25 - R23/24/25 - 吸入、皮肤接触及吞食有毒。 R52/53 - 安全术语S53 - 避免接触，使用前须获得特别指示说明。 S45 - 若发生事故或感不适，立即就医(可能的话，出示其标签)。 S60 - 该物质及其容器须作为危险性废料处置。 S61 - 避免释放至环境中。参考特别说明/安全数据说明书。 S62 - 若吞食，切勿催吐；立即求医，并出示其容器或标签。 S36/37 - 穿戴适当的防护服和手套。 S33 - 采取措施，预防静电发生。 S29 - 切勿倒入下水道。 S16 - 远离火源。 S9 - 保持容器置于良好通风处。 S7 - 保持容器密封。 危险品运输编号UN 3077 9/PG 3WGK Germany3RTECSCN1400000TSCAYes海关编号29270000Hazard Class6.1(b)Packing GroupIII上游原料下游产品分散橙 29 光致变色偶氮苯聚合物
