Page 7797. We have discovered that the UV–vis spectrophotometer used in this paper was incorrectly calibrated. All wavelengths were too high by 20.0 nm. For example, in Figure 9, the correct wavelength range for all traces should have been 450–780 nm, not 470–800 nm. This error was discovered because we noticed that spectra recorded in our laboratory were shifted compared to those recorded in a colleague’s laboratory in our department. After we discovered the error, we determined the correct calibration for our spectrophotometer by using the Dα and Dβ spectral lines produced by the instrument’s deuterium arc lamp. These are at 656.1 and 486.0 nm, respectively. (1,2) In the present correction, we include corrected versions of Figure 9 from the main text and Figures S3 and S4 in the Supporting Information. In the corrected spectra, the absorption maxima for C₆₀ and C₇₀ agree well with the literature values. (3,4) Also, we realized that the maxima and extinction coefficients for Cu₄(m-pbhx)₄ in Figures S3 and S4 are difficult to read because its absorption bands are much weaker than those of the fullerene guests and the host–guest adducts. Therefore, we have also included Figure S5, which shows the spectra of Cu₄(m-pbhx)₄ by itself in toluene and 1,2-dichlorobenzene. Figure 9. Portions of the electronic absorption spectra of solutions of Cu₄(m-pbhx)₄ and C₆₀ in 1,2-dichlorobenzene. All solutions contain 0.167 mM C₆₀. Concentrations of added Cu₄(m-pbhx)₄ increase in order from the bottom spectrum upward: 0, 0.0922, 0.184, 0.461, 0.738, 1.01, 1.29, and 1.57 mM. The absorption maxima (λ_max) for these spectra are not mentioned in the text or the Supporting Information of the original paper. Also, calculations of the binding constants (Table 2) depend only on the absorbances, not the λ_max values. Thus, this correction does not require any other changes in the paper. In the corrected Supporting Information, the only changes made were to correct the x (wavelength) axes for the electronic spectra in Figures S3 and S4. A new Figure S5 was added, showing just the wavelength-corrected spectrum of Cu₄(m-pbhx)₄, because it is difficult to see on the larger vertical scales of Figures S3 and S4. All other text, figures, and tables in the Supporting Information are unchanged.

更正为“外部和内部功能化铜 （II） β-二酮酸盐分子方块”


第 7797 页。我们发现本文中使用的紫外-可见分光光度计校准不正确。所有波长都太高了 20.0 nm。例如，在图 9 中，所有迹线的正确波长范围应为 450-780 nm，而不是 470-800 nm。发现此错误的原因是我们注意到，与我们部门同事实验室记录的光谱相比，我们实验室记录的光谱发生了偏移。发现错误后，我们通过使用仪器氘弧灯产生的 Dα 和 Dβ 光谱线确定了分光光度计的正确校准。它们分别位于 656.1 和 486.0 nm。（1,2） 在本更正中，我们在支持信息中包括了正文中图 9 和图 S3 和 S4 的更正版本。在校正后的光谱中，C₆₀ 和 C₇₀ 的最大吸收值与文献值非常吻合。（3,4） 此外，我们意识到图 S3 和 S4 中 Cu₄（m-pbhx）₄ 的最大值和消光系数难以读取，因为它的吸收带比富勒烯客体和主客体加合物的吸收带弱得多。因此，我们还包括了图 S5，它显示了 Cu₄（m-pbhx）₄ 本身在甲苯和 1,2-二氯苯中的光谱。图 9.Cu₄（m-pbhx）₄ 和 C₆₀ 在 1,2-二氯苯中的溶液的部分电子吸收光谱。所有溶液均含有 0.167 mM C₆₀。添加的 Cu₄ （m-pbhx）₄ 的浓度从底部光谱开始依次增加：0、0.0922、0.184、0.461、0.738、1.01、1.29 和 1.57 mM。 这些光谱的吸收最大值 （λ_max） 在原始论文的正文或支持信息中未提及。此外，结合常数的计算（表 2）仅取决于吸光度，而不取决于 λ_最大值。因此，此更正不需要对论文进行任何其他更改。在更正后的支持信息中，所做的唯一更改是校正图 S3 和 S4 中电子光谱的 x（波长）轴。添加了一个新的图 S5，仅显示了 Cu₄（m-pbhx）₄ 的波长校正光谱，因为在图 S3 和 S4 的较大垂直尺度上很难看到。支持信息中的所有其他文本、图形和表格保持不变。该文件完整提供，包括所有图表、文本和表格，因此读者无需查阅原始支持信息。支持信息可在 https://pubs.acs.org/doi/10.1021/acs.inorgchem.4c04736 免费获取。 Cu₄（m-pbhx）₄（μbpa）（CH₃OH）₂ （24） 的晶体结构图和 [Cu₄（m-pbhx）₄（μ-C₇₀）] 中所有四个 C₇₀ 客体分子的取向图 （27），Cu₄（m-pbhx）₄、Cu₄（m-pbhx）₄（μ-C₆₀） 和 Cu_{4 的光谱数据}（m-pbhx）₄（μ-C₇₀） 和 10、11、13、23、24、25、26 和 27 的 X 射线晶体学数据，以汇总表和 CIF 格式 （PDF）更正“外部和内部功能化铜 （II） β-二酮酸盐分子方块” 1 次浏览 0 分享 0 下载 大多数电子支持信息文件无需订阅 ACS Web 版本即可获得。此类文件可以按文章下载用于研究用途（如果有链接到相关文章的公共使用许可证，则该许可证可能允许其他用途）。可以通过 RightsLink 权限系统（http://pubs.acs.org/page/copyright/permissions.html）请求，从 ACS 获得用于其他用途的权限。我们感谢 Isiah M.
