Although tris(4,7-diphenyl-1,10-phenanthroline)ruthenium(II) complex [Ru(DPP)3] is generally immobilized in sol-gels by doping method for the development of optical sensors, such methods cause leaching of dye molecules from the matrix during liquid-phasing sensing to result in reducing sensor lifetime. To circumvent this problem, the hydrophobic dendrimers were covalently attached to Ru(DPP)3, which was immobilized in sol-gel matrix by doping method. We have investigated the extent of the dye leaching and sensitivity of the sensing membrane in aqueous environment. |
