On the interaction of triarylmethane dye crystal violet with LAPONITE® clay: using mineral nanoparticles to control the dye photophysics.

The combination of an organic dye with clays leads to very interesting hybrid materials with original properties. It is found that LAPONITE® nanoparticles have an impact on the photophysical properties of the crystal violet dye inducing a kinetic stabilization of its excited emissive state, turning this nonemissive dye into a fluorescent compound.
