Control of Circularly Polarized Electroluminescence in Induced Twist Structure of Conjugate Polymer

Adv. Mater. 2017, 29, 1700907 The following errors appeared in the above-mentioned article are hereby corrected. The gEL factors of the circular polarized electroluminescence (CPEL) have to be evaluated by inversion of coordinates in the analysis of Stokes parameters for the reflected light from the cathode. In turn, the gEL values associated with the recombination zone are affected in Figure 3b and Figure 4c-e. In addition, Figure S8 in the Supporting Information file is corrected as well. In Figure 3b, the measured values of gEL as a function of the twist angle are well described by extending the recombination zone to 10 nm from the TPBi layer. These amendments do not affect the original experiments and conclusions of the article since the recombination zones of our CPEL devices are located near the cathode and all amended figures except for Figure 3b do not explain the experimental results, but give theoretical predictions for various parameters. The last three sentences in the right column on the fourth page should read: Therefore, we can assume that the recombination zone can be extended to 10 nm from the TPBi layer in our system. The solid line in Figure 3b represents the average of the gEL profiles at z = 0 and 10 nm, and well describes the abnormal behavior of the gEL values. For the calculation, we used Δn = 0.67 at λ = 546 nm, PEL = 0.875, and d = 200 nm. The averaged gEL over 10 nm from the TPBi layer of Figure 3b must also be amended and is shown below: Figure 3. The theoretical predictions for various parameters of Figure 4c–e are also corrected. The corrected Figure 4 is shown here: Figure 4 In turn, the corrected Figure S8 is also shown as follows: Figure S8 All the conclusions of the paper remain valid. The authors apologize for any inconvenience that may have been caused due to these errors.
