Abstract
Co-crystallisation of the anionic cyanometallate chromophore [Ru(bipy)(CN)4]2- with Yb(III) provides coordination polymers or oligomers containing Ru-CN-Yb bridges; in [K(H2O)4][Yb(H2O)6][Ru(bipy)(CN)4]2.5H2O Ru-->Yb energy-transfer (k > 5 x 10(6) s(-1)) results in partial quenching of the Ru-based luminescence and sensitised near-IR luminescence from the Yb(III) unit.
摘要
阴离子氰基金属发色团[Ru(bipy)(CN)₄]²⁻与Yb(III)的共结晶提供了含有Ru-CN-Yb桥的配位聚合物或低聚物；在[K(H₂O)₄][Yb(H₂O)₆][Ru(bipy)(CN)₄]·2.5H₂O中，Ru→Yb能量转移（k > 5×10⁶ s⁻¹）导致基于Ru的发光部分猝灭，并敏化了来自Yb(III)单元的近红外发光。
