The low statistical probability factor of the rubrene emitter (<italic>f</italic> = 15.5 ± 3%) was determined to be prime TTA-UC efficiency-limiting factor.
Solid state NIR-to-visible photon upconversion (UC) mediated by triplet-triplet annihilation (TTA) is necessitated numerous practical applications. Yet, efficient TTA-UC remains a highly challenging task. In this work palladium phthalocyanine-sensitized NIR-to-vis solid UC films based on popular rubrene emitter are thoroughly studied with the primary focus revealing impact of t-butyl substitution in performance. The solution-processed were additionally doped small amount emissive singlet...
Peripheral linking of rubrene emitters is found to deliver enhanced TTA efficiency <italic>vs.</italic> core linking. This provides valuable insight for their rational modification towards improved NIR-to-vis photon upconversion in the solid state.
