Abstract

Attention is focused on the use of simple binary metal carbonyls for the nucleation, growth, and stabilization of intrazeolite semiconductor quantum nanostructures. The rationale for selecting this particular group of precursor molecules relates to their volatility, molecular dimensions, ease of purification, availability, and facile and quantitative conversion to the respective metal oxide materials with minimal contamination by carbon. In this study the intrazolite photooxidation chemistry of α-cage encapsulated hexacarbonyltungsten(0) in Na56Y and H56Y, n{W(CO)6}-Na56Y(H56Y), with O2 provides a novel synthetic pathway to α-cage-located tungsten(VI) oxide n(WO3)-Na56Y(H56Y) intrazeolite quantum dots and a zero-dimensional semiconductor quantum supralattice (where n = 0-32), which might find applications as new solid-state materials for use in quantum electronic and nonlinear optic devices. © 1990 American Chemical Society.
