摘要：

Three new rigid bridging ligands for metal complexation (7 = bmb, 8 = bqb and 11 = btb) were prepared from a rigid triptycene spacer connected to two bipyridin-p ligands using a Horner-Emmons type reaction. The triptycene spacer is substituted by methoxy groups in the case of bmb and in the case of bqb by a benzoquinone substituent. The corresponding metal complexes (ruthenium and/or osmium) were synthesised and the different luminescence behaviour was tested. They show great potential for the investigation of intramolecular electron and energy transfer reactions. The dinuclear metal complex Ru-bqb-Os is an interesting system in which the bridging ligand bqb acts as a redox switch, able to tune the conductivity for energy or electrons across the bridge.
