Abstract

Densely packed hybrid monolayers of amphiphilic cyclodextrins incorporating hydrophilic porphyrins are formed at the air/water interface through electrostatic interaction and can be transferred onto quartz substrates by Langmuir–Schäfer deposition. The resulting multilayers exhibit a good response to light excitation as proven by fluorescence emission, triplet–triplet absorption and singlet oxygen photogeneration.
