Abstract
Surface modification of nanoporous tin dioxide materials with fluorinated or perylene units is achieved with trialkynylorganotin compounds (see figure). Irreversible chemisorption occurs in solution at room temperature, yielding an organic layer at the oxide surface via the cleavage of the three tin–alkynide bonds of the precursor and the formation of Snbulk–O–Sn–C linkages. The dye-sensitized nanohybrids are suitable for solar-energy conversion devices.
