Molecular orbital confinement effect of mesoporous silica of MCM-41 on conjugated polymer

摘要

A set of conjugated polymers with different molecular diameters was incorporated into channels of mesoporous silica of MCM-41. Study on UV-Vis and photoluminescent (PL) spectra of these composites revealed regular variation of band gap of frontier orbital along with the variation of diameter of the polymers by comparison with UV-Vis and PL spectra of the polymers in CHCl3 solution. The results showed evidence in support of the molecular orbital confinement effect in the composite of the conjugated polymer/mesoporous silica. (C) 2003 Elsevier Science B.V. All rights reserved.
