AbstractControl of the molecular configuration at the interface of an organic heterojunction is key to the development of efficient optoelectronic devices. Due to the difficulty in characterizing these buried and (probably) disordered heterointerfaces, the interfacial structure in most systems remains a mystery. Here we demonstrate a synthetic strategy to design and control model interfaces, enabling their detailed study in isolation from the bulk material.

IntroductionClick to copy section linkSection link copied!Lanthanide-doped nanoparticles (LnNPs) possess unique optical properties and their usage has been demonstrated in a wide range of optoelectronic applications, including upconversion, (1−3) imaging, (4−6) photocatalysis, (7,8) and lasing. (9−11) One of the key limitations of LnNPs is their low absorption cross-section, with molar absorption coefficients of lanthanide ions rarely exceeding 1 M–1 cm–1.

AbstractHyperfluorescence shows great promise for the next generation of commercially feasible blue organic light-emitting diodes, for which eliminating the Dexter transfer to terminal emitter triplet states is key to efficiency and stability. Current devices rely on high-gap matrices to prevent Dexter transfer, which unfortunately leads to overly complex devices from a fabrication standpoint.
