Cyclometalated platinum(II) 4,6-diphenyl-2,2′-bipyridine complex is supported on a commercially available cationic ion-exchange resin (amberlite IRA-200). Photophysical and ESR determinations indicate that the combined photosensitized system is able to generate singlet oxygen with high quantum yield upon irradiation of light in the visible region. The platinum(II) complex loaded on IRA-200 resin is
环金属化的铂(II)4,6-二苯基-2,2'-联吡啶配合物负载在市售的阳离子交换树脂(Amberlite IRA-200)上。光物理和ESR的测定表明,组合的光敏体系能够在可见光区域照射光时以高量子产率产生单线态氧。负载在IRA-200树脂上的铂(II)络合物是稳定的,并且以环境友好的方式发生光氧化。只需要简单的过滤就可以回收昂贵的金属催化剂。
