Distance-dependent energy transfer occurs from the Metal-to-Ligand Charge Transfer (MLCT) excited state Ru(bpy)3(2+) to an anthracene-acrylate derivative (Acr-An) incorporated into the polymer network of a semirigid poly(ethyleneglycol)dimethacrylate monolith. Following excitation, Ru(bpy)3(2+) to Acr-An triplet energy transfer occurs followed by long-range, Acr-(3)An-Acr-An → Acr-An-Acr-(3)An, energy migration. With methyl viologen dication (MV(2+)) added as a trap, Acr-(3)An + MV(2+) → Acr-An(+) + MV(+) electron transfer results in sensitized electron transfer quenching over a distance of approximately 90 Å.
从金属到配体电荷转移（MLCT）激发态 Ru(bpy)3(2+)到掺入聚合物网络中的蒽丙烯酸酯衍生物（Acr-An）的能量转移发生在半刚性聚乙二醇二甲基丙烯酸酯单体中。激发后，Ru(bpy)3(2+)到 Acr-An 三重态能量转移发生，随后是长程能量迁移，Acr-(3)An-Acr-An → Acr-An-Acr-(3)An。加入二价甲紫阳离子（MV(2+))作为陷阱，Acr-(3)An + MV(2+) → Acr-An(+) + MV(+)电子转移导致敏化电子转移猝灭，距离约为 90 Å。
