Although multiresonance thermally activated delayed fluorescence (MR-TADF) materials offer exceptional color purity, their practical use is often limited by slow reverse intersystem crossing (RISC), leading to triplet accumulation, efficiency roll-off, and device degradation. Here, we report three aggregation-induced emission TADF emitters (23PalCBP, 23PclCBP, and 32PclCBP) constructed from indolocarbazole donors and a benzophenone acceptor. Among them, 32PclCBP exhibits a very small singlet\u2212triplet energy gap (\u0394EST = 0.01 eV) and a high photoluminescence quantum yield (PLQY) of 0.88 in doped films, affording OLEDs with a maximum external quantum efficiency (EQEmax) of 29.3%. When employed as sensitizers in hyperfluorescence (HF) devices with the MR-TADF emitter BNMIPAPh, both sensitized systems deliver narrowband blue emission with a full width at half-maximum of 27 nm. The 32PclCBP-sensitized device achieves a balanced performance with an EQEmax of 28.6% and a substantially reduced efficiency roll-off of 22.7% at 1000 cd m\u22122, together with modestly improved operational stability relative to the nonsensitized MR-TADF reference. In comparison, the 23PalCBP-sensitized device affords a higher EQEmax of 30.9%, albeit with a larger efficiency roll-off of 31.1%. These results demonstrate that the synergistic optimization of multiple photophysical parameters, including high PLQY, low nonradiative decay, small \u0394EST, and moderate RISC kinetics, enables efficient, high-color-purity, and low-roll-off sky-blue HF OLEDs.<\/jats:p>","DOI":"10.1021\/acsami.6c10353","type":"journal-article","created":{"date-parts":[[2026,7,27]],"date-time":"2026-07-27T09:31:59Z","timestamp":1785144719000},"page":"41366-41374","source":"Crossref","is-referenced-by-count":0,"title":["High-Performance Sky-Blue Hyperfluorescence Organic Light-Emitting Diodes Enabled by Efficient Thermally Activated Delayed Fluorescence Sensitizers with Suppressed Efficiency Roll-Off"],"prefix":"10.1021","volume":"18","author":[{"given":"Hui","family":"Dai","sequence":"first","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Zhang","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengke","family":"Li","sequence":"additional","affiliation":[{"name":"South China University of Technology , , ,","place":["Guangzhou, China, 510641"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaohui","family":"Liang","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanlin","family":"Wu","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianyi","family":"Tang","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6880-2946","authenticated-orcid":true,"given":"Shuhang","family":"Li","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhan","family":"Yang","sequence":"additional","affiliation":[{"name":"Wuyi University , , ,","place":["Jiangmen, China, 529020"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1446-408X","authenticated-orcid":true,"given":"Bo","family":"Wu","sequence":"additional","affiliation":[{"name":"Wuyi University , , ,","place":["Jiangmen, China, 529020"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan","family":"Zhao","sequence":"additional","affiliation":[{"name":"Wuyi University , , ,","place":["Jiangmen, China, 529020"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1670-9981","authenticated-orcid":true,"given":"Zhiyong","family":"Yang","sequence":"additional","affiliation":[{"name":"Sun Yat-sen University , , ,","place":["Guangzhou, China, 510275"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6545-9002","authenticated-orcid":true,"given":"Shi-Jian","family":"Su","sequence":"additional","affiliation":[{"name":"South China University of Technology , , ,","place":["Guangzhou, China, 510641"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9772-5363","authenticated-orcid":true,"given":"Zhenguo","family":"Chi","sequence":"additional","affiliation":[{"name":"Wuyi University , , ,","place":["Jiangmen, China, 529020"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"2026080518073842600_cit1","doi-asserted-by":"crossref","first-page":"1166","DOI":"10.1039\/D2QM01241C","article-title":"Solution-processed OLEDs for printing displays","volume":"7","author":"Zeng","year":"2023","journal-title":"Mater.
