Line 1. Multifunctional laser dyes based on BODIPY

The BODIPYs stand out for their great synthetic versatility; its chromophoric nucleus is reactive for numerous synthetic routes, which allows functionalizing selectively. Therefore, the photophysical properties of BODIPY can be modulated through the substitution pattern, which allows the development of dyes with properties on demand and with multiple applications.

Line 2.  Photosensitizers for the generation of singlet oxygen in photodynamic therapy

The BODIPYs have focused great interest as photosensitizers; through its functionalization, highly fluorescent dyes can be transformed into "dark" dyes with a high population of their triplet state. In addition, their photophysics, which are not very sensitive to environmental conditions, high lipophilicity and high resistance to photodegradation, make them ideal candidates for PDT.

2.2. Nanoparticles as hosts of the photosensitizers for their implantation in photodynamic therapy and teragnosis.

Line 3. Multifunctional photoactive materials

The confinement of fluorescent dyes in organic and inorganic supports increases its photo and thermostability. In addition, the environmental rigidity infers to the fluorophore a constricted environment in such a way that it limits its molecular movement, avoids the formation of non-fluorescent aggregates and induces a preferential orientation of the dye, giving rise to very ordered materials. Therefore, these materials stand out for a high fluorescent signal and are susceptible to be applied in various scientific fields.
