✦ Synopsis

The synthesis of a new insoluble, hydrophilic, polymeric equivalent of the Ru(bpy)3 -'+ complex is described. Sephadex is used as a hydrophilic polymeric skeleton. Its photophysical properties are similar to those of Ru(bpy) 32 + in solution. The deactivation of this polymeric excited complex by methyl viologen (oxidative quenching) and N,N-dimethylaniline (reductive quenching) is very efficient in polar solvents, making it both a powerful oxidant and reductant species in photochemical reactions accomplished in heterogeneous phase.
