A composite of zinc tetraphenylporphyrin linked with beta-cyclodextrin was prepared as a convenient scaffold for a self-assembled energy-transfer complex. The energy-transfer properties of the host-guest complexes were investigated for several guest molecules (naphthalene, anthracene, 2-methylanthracene, and 9,10-dimethylanthracene) by means of fluorescence and fluorescence-excitation spectroscopies.
