Circularly polarized luminescence(CPL) materials have received widespread attention due to their remarkable performance and broad applications. However, current CPL material research primarily focuses on tunable color, intensity, and *** CPL with adjustable lifetime remains a significant challenge. Herein, a series of CPL polymeric materials with tunable lifetime were obtained by employing phosphorescent terephthalic acid and chiral organic small molecule R/S-BNAF(a luminescent binaphthol derivative) to copolymerize with acrylamide in different ratios. It was verified that this performance results from the different energy transfer efficiency between luminophores with varying ratios of the monomers for copolymerization. This strategy to realize CPL with tunable lifetime by modulating the energy transfer efficiency will provide a new perspective to broaden the applications of CPL materials.

To develop efficient sensitizers for dye-sensitized solar cells(DSSCs),we recently reported doubly concerted companion(DCC)dye XW83 with a wrapped porphyrin sub-dye unit linked to an organic sub-dye unit through a flexible chain,which exhibits panchromatic absorption and excellent anti-aggregation *** further improve the absorption,we herein report XW87 and XW88 by inserting an ethynyl group into the organic sub-dye unit of XW83 near the donor and acceptor,*** the corresponding organic dyes Z3 and Z4,the introduced ethynyl group improves their absorption,but induces aggravated charge recombination,leading to lowered power conversion efficiencies(PCEs).Similar to the organic dyes,the introduced ethynyl group improves the absorption of DCC dyes XW87 and XW88 as *** addition,the ethynyl group near the acceptor of the organic sub-dye unit can be well protected by the long wrapping chains from the porphyrin *** a result,XW88 affords the highest JSC(21.84 mA/cm^(2)),V_(OC)(782 mV)and PCE(12.2%)among the DCC *** results provide an effective method for developing efficient DSSC dyes by inserting an ethynyl group at a suitable position of a DCC dye.

锡氧团簇极紫外光刻胶中的Sn–C键在曝光时发生裂解并产生自由基,导致锡氧核的连接和溶解度变化. Sn–C键的反应活性和所产生自由基在薄膜中的迁移会对图案化结果（灵敏度和分辨率）产生重大影响.在此,我们将Sn4-Me-C10（含Sn–methyl键）和Sn4-Bu-C10（含Sn–butyl）这两种锡氧团簇结合起来,利用Sn–C键裂解产生的甲基和丁基自由基之间的反馈调节来平衡光刻胶的灵敏度和分辨率. Sn4-Bu-C10在低EBL曝光剂量下产生的丁基自由基引发Sn4-Me-C10的光刻反应,从而提高了灵敏度;随后, Sn4-Me-C10产生的不稳定甲基自由基和体积较大的金刚烷自由基淬灭过量的丁基自由基,从而提高了分辨率和曝光裕度.这种利用自由基反馈调节的方法为设计具有高分辨率、高灵敏度的锡氧团簇EBL光刻胶提供了新的思路.

花菁染料的J-聚集体因其独特的红移吸收和优异的光热转换效率（PCE）而在肿瘤光热治疗（PTT）中显示出巨大的优势.然而,由于分子间相互作用的复杂性,探索新的策略来调控有机材料的聚集模式仍然具有挑战性.在本文中,我们设计了两个金属Pt配位的花菁二聚体CyRPt （R=Me,Et）,并在水溶液中自发自组装成聚集体.CyEt-Pt聚集体为疏松和无定形堆积.通过用甲基取代乙基以减少空间位阻,这一微小的变化导致在CyMe-Pt自组装中出现了紧密有序的J-聚集体.这种意外的“蝴蝶效应”使CyMe-Pt J-聚集体表现出NIR-Ⅱ吸收、优异的光稳定性以及突出的光热性能（PCE=37%）.在980 nm激光以安全功率(0.5W cm-2)照射下,CyMe-Pt J-聚集体显著抑制肿瘤生长,证明了其在肿瘤PTT中的巨大潜力.

Indium oxide(In_(2)O_(3)),as a promising candidate for CO_(2)hydrogenation to C_(1) products,often suffers from sintering and activity decline,closely related to the undesirable structural evolution under reaction *** on the comprehension of the dynamic evolution,this study presents an efficient strategy to alleviate the agglomeration of In_(2)O_(3)nanoparticles by the surface decoration with highly dispersed silica species(SiO_(x)).Various structural characterizations combined with density functional theory calculations demonstrated that the sintering resulted from the over-reduction,while the enhanced stability originated from the anchoring effect of highly stable In-OSi bonds,which hinders the substantial formation of metallic In(In^(0))and the subsequent agglomeration.0.6Si/In_(2)O_(3)exhibited CO_(2)conversion rate of10.0 mmol g^(-1)h^(-1)at steady state vs.3.5 mmol g^(-1)h^(-1)on In_(2)O_(3)in CO_(2)*** steady-state activity was also achieved on Pd-modified *** to the traditional Pd/In_(2)O_(3)catalyst,the methanol production rate of Pd catalyst supported on 0.6Si/In_(2)O_(3)was enhanced by 23%,showing the potential of In_(2)O_(3)modified by SiO_(x)in serving as a platform *** work provides a promising method to design new In_(2)O_(3)-based catalysts with improved activity and stability in CO_(2)hydrogenation.
