The homoleptic zinc(II) and ruthenium(II) metal complexes of bis(tridentate) 9-acridine and 10-methyl-9-acridinium-substituted terpyridines were tested for their suitability as triplet photosensitizers (PS) using the photooxidation of 1,5-dihydroxynaphthalene (DHN) to Juglone as a model reaction. Singlet oxygen (O2(1)Δg) generation is superior or comparable to Ru(bpy)3(2+) for the acridine complexes, whereas the acridinium complexes are ineffective. The molecular structure of the bis(9-(5-([2,2':6',2''-terpyridin]-4'-yl)thien-2-yl)-10-methylacridinium)zinc(II) complex ([Zn(MeATT)2][PF6]4) is determined by X-ray structure analysis, whereas for other complexes DFT calculations were performed for structural parameters to obtain insights into their electronic properties.
用 1,5-二羟基萘（DHN）光氧化为模型反应，测试了双（三齿配体）9-吖啶和 10-甲基-9-吖啶鎓取代的三吡啶钌（II）和锌（II）配合物作为三重态光引发剂（PS）的适用性。对于吖啶配合物，单线态氧（O2(1)Δg）的生成优于或可与 Ru(bpy)3(2+)相媲美，而吖啶鎓配合物则无效。双（9-（5-（[2,2':6',2''-三联吡啶]-4'-基）噻吩-2-基）-10-甲基吖啶鎓）锌（II）配合物([Zn(MeATT)2][PF6]4)的分子结构通过 X 射线结构分析确定，而对于其他配合物，则进行了 DFT 计算以获得结构参数，从而深入了解其电子性质。
