Quality through diversity has been a hallmark of Angewandte Chemie from the beginning, and this is no doubt also the case in the 125th year. This jubilee will be celebrated by a symposium on March 12, 2013 in Berlin, and the program is part of the current issue. The diversity of topics that appear in Angewandte Chemie is illustrated by the tag cloud in the cover picture. The diversity of countries from which manuscripts come is shown by the top-ten list of countries of the Communications accepted in 2012, which is represented by the size of the spheres in the cover picture. The various sections are also diverse: Reviews and Communications, Highlights and Essays, Author Profiles and News, Obituaries and occasionally Correspondences. The history of Angewandte Chemie is presented in this Issue by the Chairman of the Editorial Board, François Diederich, in a major Review (pp. 2714 ff.), which brings to life the development of the journal and indeed of chemistry since 1888.
In their Communication on page 2874 ff., A. J. Heeger et al. show how to insert electron-transport layers of transferable graphene oxide into bulk-heterojunction solar cells for enhanced power-conversion efficiency.
Ultralight, flexible, and fire-resistant carbon nanofiber aerogels, which can be fabricated in large scale by using bacterial cellulose as a precursor, are described by S. H. Yu and co-workers in their Communication on page 2925 ff.
