  Acylhydrazones as Widely Tunable Photoswitches

  摘要：

  Molecular photoswitches have attracted much attention in biological and materials contexts. Despite the fact that existing classes of these highly interesting functional molecules have been heavily investigated and optimized, distinct obstacles and inherent limitations remain. Considerable synthetic efforts and complex structure property relationships render the development and exploitation of new photoswitch families difficult. Here, we focus our attention on acylhydrazones: a novel, yet underexploited class of photochromic molecules based on the imine structural motif. We optimized the synthesis of these potent photoswitches and prepared a library of over 40 compounds, bearing different substituents in all four crucial positions of the backbone fragment, and conducted a systematic study of their photochromic properties as a function of structural variation. This modular family of organic photoswitches offers a unique combination of properties and the compounds are easily prepared on large scales within hours, through an atom-economic synthesis, from commercially available starting materials. During our thorough spectroscopic investigations, we identified photoswitches covering a wide range of thermal half-lives of their (Z)-isomers, from short-lived T-type to thermally stable P-type derivatives. By proper substitution, excellent band separation between the absorbance maxima of (E)- and (Z)-isomers in the UV or visible region could be achieved. Our library furthermore includes notable examples of rare negative photochromic systems, and we show that acylhydrazones are highly fatigue resistant and exhibit good quantum yields.

  isonicotinoyl hydrazone (SIH) and salicylaldehyde benzoyl hydrazone (SBH) that contain an aryl boronic ester (BSIH, BSBH) or acid (BASIH) in place of an aryl hydroxide have been synthesized and characterized as masked metal ion chelators. These pro-chelators show negligible interaction with iron(III), although the boronic acid versions exhibit some interaction with copper(II), zinc(II) and nickel(II). Hydrogen

  合成了几种新的水杨醛异烟酰酰hydr（SIH）和水杨醛苯甲酰（SBH）的类似物，它们含有芳基硼酸酯（BSIH，BSBH）或酸（BASIH）代替了芳基氢氧化物，并被表征为掩蔽的金属离子螯合剂。尽管硼酸形式与铜（II），锌（II）和镍（II）有一些相互作用，但这些螯合剂与铁（III）的相互作用可忽略不计。过氧化氢将芳基硼酸酯氧化为苯酚，从而将前螯合剂转化为具有高亲和力金属结合特性的三齿配体。双连接的铁（III）配合物[Fe（SBH（m-OMe）（3））（2）] NO（3）的X射线晶体结构证实了这些配体的子午线结合模式。螯合剂芳酰基环的修饰可调节其铁亲和力，原螯合剂的含硼环上的修饰减弱了它们与过氧化氢的反应速率。因此，甲氧基衍生物前螯合剂（p-OMe）BASIH与过氧化氢的反应比氯衍生物（m-Cl）BASIH快近5倍。前螯合剂到螯合剂的转化率以及螯合剂的金属结合亲和力都影响这些分子在过氧化氢和抗
