Cover: The figure shows the formation of a block‐selective polyrotaxane composed of PEI‐b‐PEG‐b‐PEI copolymer by pH‐controlled threading of cyclodextrins (CDs) onto the copolymer. While the CD threads indiscriminately at high pH onto the entire block copolymer, lowering the pH to 4.4 in the presence of 9‐anthraldehyde results in expulsion of the macrocycles from the PEI blocks and capping of the rotaxane by a one‐pot sequence. Further details can be found in the article by H. S. Choi, T. Ooya, and N. Yui * on page 420.
