Chromophores ligand sensitization

Whereas the binding of CBMs to insoluble carbohydrates can be monitored by the UV absorption of the protein, relatively large amounts are required, and in some of the early studies on CBDs they were made radioactive with to increase sensitivity. The general technical problem of monitoring the binding of soluble, non-chromophoric ligands to soluble CBMs, has, however, been solved only in the last decade, with the advent of isothermal titration microcalorimetry... 

Precedence for remote electron transfer like that observed in the Ti02-Ru (II)-L-Os(II) triads exists. In previous work, a supramolecular approach for designing a molecular sensitizer with controlled orientation of the component units on the semiconductor surfaces was reported (Fig. 9). The binuclear compound is based on a fac-Re(I)(dcbH2)(CO)3 surface anchoring unit and a —Ru(II)(bpy)2 chromophore linked through an ambidentate cyanide ligand [24]. Due to the facial...
