[EN] The first example of a chemosensor (L) containing a selenourea moiety is described here. L is able to colorimetrically sense the presence of CN- and S2- in H2O: MeCN (75 : 25, v/v). Moreover, when L is loaded into functionalised mesoporous silica nanoparticles an increase in the selectivity towards S2- occurs via a selective fluorescence response. ; The authors thank the financial support from the Fondazione Banco di Sardegna, the Spanish Government, European FEDER funds (project MAT2015-64139-C4-1-R) and the Generalitat Valenciana (project PROMETEOII/2014/047). A. Llopis-Lorente is grateful to the "La Caixa'' Banking Foundation for his PhD fellowship. Dr Tiziana Pivetta is gratefully acknowledged for help with the interpretation of the mass spectra. ; Casula, A.; Llopis-Lorente, A.; Garau, A.; Isaia, F.; Kubicki, M.; Lippolis, V.; Sancenón Galarza, F.
