spectra of the complexes suggest the binding of LL to platinum through their deprotonated functional groups. The infrared data further confirm the above mode of binding of LL to platinum(II). The catechol,4-tert-butylcatechol, thiosalicylic acid, 3,4-dimercaptotoluene derivatives photosensitized 3O2 to 1O2 in presence of light. The 1O2 thus produced combines with 2,2,6,6-tetramethyl-4-piperidinol molecules
摘要六种[Pt(bipy)(LL)]的配体配合物,其中bipy是2,2'-联吡啶,LL是邻苯二甲酸,水杨酸,硫代水杨酸,邻苯二酚,4-叔丁基邻苯二酚或通过[Pt(bipy)Cl2]与适当的双阴离子螯合配体的相互作用制备3,4-二巯基甲苯。二甲基甲酰胺中的电导率数据证实这些络合物是非电解质。这些配合物的紫外光谱显示了从Bipy的d-轨道到π-反键轨道的电荷转移跃迁和Bipy配体的π-π*跃迁。此外,除邻苯二甲酸酯衍生物外,所有配合物中均在16-23 kK(emax = 2000至3000 l mol-1 cm-1)之间观察到强谱带。该带是溶剂依赖性的,并被分配给配体到配体的电荷转移。配合物的1 H NMR光谱表明LL通过去质子化的官能团与铂结合。红外数据进一步证实了LL与铂(II)结合的上述模式。邻苯二酚,4-叔丁基邻苯二酚,硫代水杨酸,3,4-二巯基甲苯衍生物在光的存在下将3O2光敏化为1O2。由此产生的1O2与2
