Horretarako, perileno gorria, BODIPY eta kumarina kobalenteki lotu dira talde banatzaile aproposa dela medio. Diseinu molekular honek argi bilketa handitu ez ezik, kitzikapen eremuarekiko menpekotasunik gabeko argi gorria lortzea ahalbidetzen du ere, intramolekularra den energia transferentzia prozesu eraginkorren ondorioz.The herein reported work deals about the characterization of the photophysical signatures as well as the structural and electronical properties of multichromophoric dyes by means of spectroscopic techniques and computational methods, towards the development of red-emitting tunable lasers. To this aim, perylene red, BODIPY and coumarine have been linked covalently trough suitable spacers. This molecular assembly not only improves light harvesting, but also provides solely red-edge emission regardless of the excitation spectral region owing to consecutive and efficient intramolecular energy transfer processes.Laser koloratzaileakenergia transferentziaantena molekularrak.Dye lasersenergy transfermolecular antennasFisikaKimikaintroduction
