Bimolecular exciton annihilation reactions are one of the leading causes of molecular degradation in these devices, but are so far quantified mostly by fitting data to simplified rate equation models that crudely approximate the exciton and charge carrier densities in the recombination zone while neglecting the other layers in the device entirely. Here, we implement a rigorous drift-diffusion-based degradation model and compare its luminance fade and voltage rise to that of a corresponding rate-based model for a prototypical exciton-polaron-based degradation scenario. We find that the luminance fade predicted by the rate model yields functionally similar, but quantitatively different results than the drift-diffusion simulation, though reasonable agreement can be achieved by using effective values for the annihilation rate coefficient and hot polaron degradation probability. Importantly, the drift-diffusion model indicates that trap state defects formed in the emissive layer lead to only a minor increase in voltage, whereas those formed in the transport layers lead to a larger increase that is on par with experiment. These results suggest that OLED luminance loss and voltage rise largely originate from different sets of defect states formed in the emissive and transport layers, respectively, and that rate model degradation parameters fit from experiment should be viewed as effective values that do not directly correspond to the rate of the actual microscale processes occurring in the device.</div></div>","PeriodicalId":22245,"journal":{"name":"Synthetic Metals","volume":"311 ","pages":"Article 117797"},"PeriodicalIF":4.0,"publicationDate":"2024-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143173549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensor is based on a ZnO nanoflower/Graphene/Nafion coated glassy carbon electrode (ZnO NF/GR/Nafion/GCE) and a supercapacitor electrode with the same electrode component. The morphological characterisation of the prepared sensor and supercapacitor electrode was conducted via scanning electron microscopy (SEM), structural characterisation by X-ray diffraction spectroscopy, chemical characterisation by Fourier transform infrared spectroscopy (FT-IR) and Raman analysis. The electroactivity and selectivity of the ZnO NF/GR/Nafion sensor platform towards IBU and PAR were simultaneously investigated by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS). Electrochemical tests of the sensor were conducted in a three-electrode electrochemical system in 0.1 M B-R buffer (pH 4.0). The linear ranges of the ZnO NF/GR/Nafion sensor towards PAR and IBU were determined in the range of 1.0 and 1000.0 μM. The detection limits for PAR and IBU were calculated as 0.28 µM and 0.31 µM, respectively. In real sample analyses, the efficiency of the investigated sensor in different drug formulations was found to respond to PAR and IBU with high recovery (99.05 % and 103.35 %). The supercapacitor electrode was prepared by changing the same electrode component, amounts and ratios of the components. The performance of the supercapacitor electrode was investigated in the potential range from 0 V to 1.2 V in PVA-H₂SO₄ electrolyte. The supercapacitor electrode demonstrated a specific capacitance of 488.1 F g⁻¹ at a scan rate of 5 mV s⁻¹ and a capacitance value of 405.5 F g⁻¹ at a current density of 7 mA.cm⁻². In this study, the ZnO NF/GR/Nafion/GCE hybrid electrode produced is used as both sensor and supercapacitor electrode material and operates in dual mode. The production method is cheap and simple, and no additional modifications are needed in the production of electrode components.

While p-AQM molecules are known to be relatively unstable, it is demonstrated here that the Q-D polymers can be reversibly oxidized, indicating that p-doping does not generate highly reactive radical species on the methylene carbons of the alkoxy-substituted p-AQM units. This distinctive behavior of polymers <em>vs</em> small molecules can be attributed to a more efficient delocalization of radicals over the conjugated backbone.
