Fluorescence patterning through photoinduced migration of squaraine-functionalized azo derivatives

New photochromic and fluorescent dyes are formed by covalently attaching emissive squaraine units to azo moieties. Illumination of doped matrices by light interference fringes provokes the reversible migration of the dyes and the formation of…

Ion-responsive supramolecular fluorescent systems based on multichromophoric calixarenes: A review

Calixarenes are useful building platforms in the design of multichromophoric systems in which photoinduced phenomena (electron, charge and proton transfers, excimer formation and resonance energy transfer) are controlled by ions. The applications…
