摘　　要：In this study,we report the preparation and application of the AlC4Pc-magnetic silica nanotubes(AlC4Pc-MSNs),which was synthesized via alumina template membrane method.The synthesized outer-NH2-magnetic silica nanotubes(outer-NH2-MSNs)were characterized by TEM,SEM,EDS and SQUID.Besides these,UV-Vis absorption spectra and fluorescence spectra were also recorded,which further indicate that the AlC4Pc-MSNs have the similar features with free AlC4Pc.The AlC4Pc-MSNs not only have all the advantages of silica nanotubes,but also can be easily separated from the solution by external magnetic field.On the basis of the merits mentioned above,AlC4Pc-MSNs was used for the detection of pH value.Our work herein reveals that the outer-NH2-MSNs will be a promising platform for the applications of the targeting drug delivery,DNA transfection,selective separation,catalyst carriers and so on.In this study, we report the preparation and application of the AlC4 Pc-magnetic silica nanotubes （AlC4 Pc-MSNs） , which was synthesized via alumina template membrane method.
