32_01/1993The cover picture shows the structure of a complex formed by self-association of six Cu1 ions (in red), as well as three quaterpyridine (in blue) and two hexaazatriphenylene ligand molecules (in yellow). If a suitable guest molecule were spontaneously and selectively included within the cavity of the complex during self-assembly, this would represent the close association of 12 (!) partners in an elective community (EC), a process in the spirit of 1993 alluded to by the European flag in the background. More on the synthesis and properties of the eleven-component complex may be found in the communication by J.-M. Lehn et al. on p. 69 ff.We are particularly pleased to be able to present this complex in the January issue of our 1993 volume, since the ANGEWANDTE has long considered itself a European and international chemical journal. In the past decade the proportion of English manuscripts from Europe and countries further afield has more than doubled—from 20% to 56%— and that accompanied by the increasing quality of the manuscripts. In 1992 about 70% of the manuscripts came from Western Europe, 20% from the USA, 7% from Japan, and the remainder from about ten other countries. In the year of Europe 1993 we wish to continue along this road that we have set out upon and to contribute in a small way to making borders easier to cross or even redundant. With the term borders, however, scientists do not think of a country's borders, but the borders of their disciplines. The publication of interdisciplinary research serves to ensure that these do not become more rigid and impenetrable. One example in this issue is the review of K. Eichmann (see p. 54 ff.) on Immunobiochemistry, a field that should also attract the interest of organic and analytical chemists. And finally let us not forget the borders of our knowledge. Another aim of ANGEWANDTE CHEMIE is to show that these limits can continually be extended. To highlight chemistry beyond the frontiers of our present knowledge—just that is the goal of our program in 1993.
