Arylisoquinoline-derived organoboron dyes with a triaryl skeleton show dual fluorescence

Pais, Vania F.; Neumann, T.; Vayá Pérez, Ignacio; Jiménez Molero, María Consuelo; Ros, Abel; Pischel, Uwe (Beilstein-Institut, 2019-11-04)

[EN] Four new dyes that derive from borylated arylisoquinolines were prepared, containing a third aryl residue (naphthyl, 4-methoxynaphthyl, pyrenyl or anthryl) that is linked via an additional stereogenic axis. The triaryl ...
Azo dyes functionalized with alkoxysilyl ethers as chemodosimeters for the chromogenic detection of the fluoride anion

Agostini, Alessandro; Milani, Michele; Martínez Mañez, Ramón; Licchelli, Maurizio; Soto Camino, Juan; Sancenón Galarza, Félix (Wiley-VCH Verlag, 2012-09)

Finding fluoride: An azo dye functionalized with tert-butyldimethylsilyl ether has been synthesized and used as a selective chromogenic fluoride sensor in the acetonitrile/water mixtures. The chromogenic response arises ...
