In this case, dual donor moieties and a single acceptor moiety are introduced to form two three-dimensional (3D) emitters, DM-BD1 and DM-BD2, which rely on spatial charge transfer (CT). Owing to the enforced face-to-face D/A/D pattern, effective CT interactions are realized, which lead to high photoluminescence quantum yields (PLQYs) of 94.2 % and 92.8 % for the two molecules, respectively. The resulting emitters exhibit small singlet-triplet energy splitting (ΔEST ) and fast reverse intersystem crossing (RISC) processes. Maximum external quantum efficiencies (EQEs) of 28.0 % and 26.6 % were realized for devices based on DM-BD1 and DM-BD2, respectively, which are higher than those of their D/A-type analogues. To determine patient knowledge of the nature of their pain management in the ED. This was a planned sub-study of data collected during a randomised, controlled trial of the nature of the informed consent process in a single ED. Patients aged ≥18 years, with a triage pain score of ≥4, were enrolled. Forty-eight hours post-ED discharge, patients were asked if they had declined analgesia or if a range of pain management options had been administered. The primary outcome was discordance between the patient report and the ED report (proportion of cases where these reports differed). Outcome data were collected on 655 patients. There was significant discordance for all variables examined (P < 0.001). Discordance for patients declining analgesia was lowest at 8.9% (95% confidence interval [CI] 6.8-11.4). Discordance for administration of pain management 'other' than analgesia was highest at 32.6% (95% CI 29.0-36.4). Discordance for the administration of oral analgesia or 'any' analge
