摘要：

The translational and orientational movement of single terrylenediimide dye molecules incorporated as guests in the nanometer-sized pores of an M41S host silica film is observed simultaneously (see figure). By correlating the dynamics of position and orientation as well as orientation and emission spectra of single molecules, the nanoscaled heterogeneities of the mesoporous host are determined.
