✦ Synopsis

Abstract

The cover picture shows the crystal structure of the cationic organometallic κ‐conjugated push–pull chromophore combining the mixed sandwich acceptor group [CpFe(η^6^‐p‐MeC~6~H~4~)]^+^, associated with the 2‐tert‐butyl‐4__H__‐chromen‐4‐ylidene donor through the asymmetric hydrazone spacer –NH–N=CH–. This dipolar chromophore exhibits solvatochromic properties, low‐lying intramolecular charge‐transfer transition and enhanced second‐order NLO properties (μβ), as measured with the EFISH technique at 1.907 μm. The scientific cooperation between researchers from the Southern Hemisphere (Chile) and the Northern Hemisphere (France) is symbolised not only by the Southern Cross but also by the NaCl crystals of the salt desert El Salar de Atacama. Details are discussed in the article by C. Manzur, D. Carrillo, B. Caro, J.‐R. Hamon et al. on p. 1131 ff.
