Azo compounds have long been investigated, particularly in connection with the development of new dyes. In addition, it is well known that photoisomerization (trans 【tautomer】 cis) of azobenzene occurs by irradiation of the π-π^* and n-π^* bands with UV light. Recently, research interest has focused on the photo- and thermochromic properties of metal complexes containing azo ligands, because they are applicable to optical sensors, photo-switching devices, molecular memory storage, and so on.In this work, we report synthesis, structures, and photo and thermal reactivity of new palladium(II) and platinum(II) complexes containing azo ligands.1. Complexes containing a ligand derived from 4-aminoazobenzene and 2-(diphenyl-phosphino)benzaldehyde : Photoisomerization (cis → trans) of azo moiety occurred by irradiation with UV light (330 nm).2. Complexes containing a ligand derived from l-phenylazo-2-naphthylamine and 2-(diphenylphosphino)benzaldehyde, 2-(tert-butylthio)benzaldehyde, or 2-pyridinealdehyde : Reversible ring opening and closure reactions of the didentate ligands occurred.

偶氮化合物长期以来一直被研究，特别是与新染料的开发有关。此外，偶氮苯的光异构化（反式【互变异构体】顺式）发生在紫外光照射π-π^*和n-π^*带时。含偶氮配体的金属配合物的光致变色和热致变色性能是近年来研究的热点，因为它们可以应用于光传感器、光开关器件、分子记忆存储等领域。在这项工作中，我们报道了新的含偶氮配体的钯（II）和铂（II）配合物的合成、结构和光热反应性。含4-氨基偶氮苯和2-（二苯基膦）苯甲醛配体的配合物：紫外（330 nm）照射下偶氮部分发生顺式→反式光异构化。含有由l-苯基偶氮-2-萘胺和2-（二苯基膦）苯甲醛、2-（叔丁基硫）苯甲醛或2-吡啶醛衍生的配体的配合物：双齿配体发生可逆的开环和闭环反应。
