Characterization of ZnE (E=S, Se, or Te) materials synthesized using silylated chalcogen reagents in mesoporous MCM-41

Article Abstract:

The binary materials ZnS, ZnSe, and ZnTe are prepared within the mesoporous framework of MCM-41 at room temperature through the use of silylated chalogen reagents. The ZnE-MCM-41 materials are characterized and the observed blue shift in the absorption maximum has agreed well with the expected quantum confinement of these materials given the nanometer dimensions of the mesoporous architecture of the silicate host.

Triplet energy migration in layer-by-layer deposited ultrathin polymer films bearing tris(2,2'-bipyridine)ruthenium(II) moieties

Article Abstract:

Ultrathin polymer films bearing tris(2,2'-bipyridine)ruthenium(II) moieties are fabricated by the layer-by-layer deposition technique. The triplet energy migration among the Ru moieties is examined by emission spectroscopy for quenching of the phosphorescence of the Ru moiety by a ferrocence moiety in heterostructured layer-by-layer films.
