Clathrate Compounds, Molecular Inclusion Phenomena, and Cyclodextrins

The Joint Meeting comprisIng the 3rd International Symposium on Clathrate Compounds and Molecular Inclusion Phenomena and the 2nd International Symposium on Cyclodextrins was held on 23-27 July, 1984, in Tokyo, Japan. It was organized by the Japan Association for Inclusion Chemistry together with the International Organization Committee, with the auspices of sixteen societies and associations in Japan. This event was the first joint meeting with the hope of unifying the above two symposia. The program of the symposium consisted of 142 papers, including 14 invited papers. The invited papers and some selected topics were presented verbally, and all the other 118 papers were displayed in poster sessions. The symposium was held at Hoshi University in Tokyo. Due to the multidisciplinary nature of the subjects treated, the scope and subjects were grouped into two parts. In the first group, the chemistry of cyclodextrins, synthetic organic hosts, inorganic and metal complex hosts and layered hosts were treated. In the second group applications in various fields, biomimetic aspects, physicochemical aspects, selectivity, stereo-specificity and other aspects were discussed. The scientific sessions were carried out in a really vivid atmosphere. The number of participants viz 50 from 19 overseas countries and 253 domestic partici­ pants exceeded our expectation.
