Chirality effects on energy transfer from polypyridyl Ru(II) to Os(II) complexes in Langmuir-Blodgett films
Energy transfer rate (k(2)) from optically active tris(4,7diphenyl-1,10-phenanthroline)ruthenium(I (denoted by Ru(II)) to Os(II) has been studied in Langmuir-Blodgett (LB) films; k(2) is found to be larger for Lambda-Ru(II)/Delta-Os(II) than for Lambda-Ru(II)/Lambda-Os(II) in a Y-type mixed film of Ru(II) and Os(II), while streoselectivity is reversed in an alternatively layered Y-type LB film of Ru(II) and Os(II).
