Abstract
A novel near-infrared dye of DPP-BODIPY with a diketopyrrolopyrrole (DPP) central unit and two 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) flanking units has been synthesized and characterized. Its quasi-planar structure was confirmed by X-ray diffraction and panchromatic absorption from 300 nm to 1000 nm was exhibited both in solution and in solid state. Near-infrared emission at about 804 nm and low LUMO energy level at −3.93 eV are observed. Furthermore, ambipolar charge transporting properties with hole mobility of 1.5×10-5 cm2 V-1 S-1 and electron mobility of 2×10-6 cm2 V-1 S-1 were obtained in thin films.
