摘要：

Up-conversion photoluminescence in a blue-emitting polymer doped with porphyrin macrocycles has been investigated and the component distribution of this system has been optimised. Covalent binding of the porphyrins to the polymer was implemented to decrease the separation of the dopant and matrix molecules, as well as dopant aggregation. The result is an up-conversion process with highly enhanced efficiency and operational stability (see picture; I=intensity). (Graph Presented) © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
