Correction to “Adaptation in Constitutional Dynamic Libraries and Networks, Switching between Orthogonal Metalloselection and Photoselection Processes” Ghislaine Vantomme, Shimei Jiang, and Jean-Marie Lehn* J. Am. Chem. Soc., 2014, 136, 9509−9518. DOI: 10.1021/ja504813r depends on the pH of the solution. The additional results coming from our further studies will be published elsewhere. As a consequence of these corrections, Scheme 4 and Scheme 5 should be replaced with the revised versions shown here. We apologize to the reader for any inconvenience. We thank Dr. Guangwen Men for performing a series of complementary measurements.
Pages 9514 and 9515. In this Article we reported on the adaptation of constitutional dynamic networks of acylhydrazones by metalloselection and photoselection. Additional experiments indicated that the metalloselection described on page 9514, right column, second full paragraph (with reference to Schemes 4 and 5), could not be reproduced. The addition of zinc triflate (5 mM) to the DCL of acylhydrazones 1A1C, 1A3C, 2A1C, and 2A3C (10 mM each) in 3:2 acetonitrile/water solution followed by overnight heating at 60 °C gives the distribution 27/23/21/25% for the constituents 1A1C/1A3C/2A1C/2A3C respectively, with 4% hydrolysis, resulting in complexation of 1A3C in the form of Zn(1A3C)2 and of 1A1C in the form of both Zn(1A1C)2 (24%) and the isomer Z-1A1C (3%) with no selection. It did not change on further heating. These percentages indicate no adaptation response of the DCL to the addition of zinc triflate. The difference in these results may come from the polarizability of the N−H bond that changes upon complexation of 1A1C to zinc cation, and

The addition of metal cation is represented by the complexation to form Zn(1A3C)2 and Zn(1A1C)2 with no selection (left). The adaptation to photoirradiation, photoselection, is represented by the selection and amplification of the Z-1A1C and 2A3C diagonal (right). The diagonals and edges of the square link respectively agonistic (+) and antagonistic (−) constituents.
