and the DSC performance of 2 are tested and compared to those of a conventional dye of structure [Ru(4,4′-(CH2PO3TBA2)2(bpy)](PF6)2 (1) (TBA = tetrabutyl ammonium). This is the first example of a ruthenium based chromophore with a phosphonic acid silyl-ester being directly immobilized onto a NiO surface. In addition, complex 2 exhibits superior stability towards desorption in aqueous media and at the
