bpy配体的顺序置换（bpy = 2，2 '-联吡啶）通过dpb配体[Ru（bpy）（3-n）（dpb）（n）]（2+）（n = 1-3）中的dpb = 2，3-双（2-吡啶基）苯并喹喔啉导致激发态寿命、（1）O（2）量子产率和与dsDNA的结合亲和力显著增加，使[Ru（bpy）（dpb）（2）]（2+）和[Ru（dpb）（3）]（2+）在红光照射（>或=600 nm）时具有有效的DNA光切割活性。
The sequential replacement of a bpy ligand (bpy = 2,2'-bipyridine) by a dpb ligand (dpb = 2,3-bis(2-pyridyl) benzoquinoxaline) in the series [Ru(bpy)(3-n)(dpb)(n)](2+) (n = 1-3) leads to a remarkable increase of the excited state lifetime, the (1)O(2) quantum yield, and the binding affinity toward dsDNA, rendering both [Ru(bpy)(dpb)(2)](2+) and [Ru(dpb)(3)](2+) efficient DNA photocleavage activities upon red light irradiation (>or=600 nm).
