A luminescent steroid-based organogel: ON-OFF photoswitching by dopant interplay and templated synthesis of fluorescent nanoparticles

The modulation of the fluorescence emission of a perylene dye between ON and OFF states was achieved with high efficiency by means of a diarylethene photochromic compound in an organogel medium. Fluorescent gels were prepared from a steroidal low molecular weight organogelator doped with the perylen...
