By analyzing TPP-C8OH in various solvents—both non-chiral and chiral—we find that chiral solvents significantly enhance the molecule's symmetry breaking and chiroptical properties. Specially, alcohol solvents, particularly dodecyl alcohol, facilitate the formation of helical structures with both left-handed (M) and right-handed (P) helices within single twisted nanoribbons. This observation contrasts with previously reported symmetry breaking phenomena in assembly systems. Chiral solvents induce assemblies with distinct helical orientations, resulting in notable circularly polarized luminescence (CPL) and circular dichroism (CD) signals.

Despite Eu3+ doped phosphors are widely used in white-LEDs, phosphors with high temperature sensitivity remain rare. Herein, NaLnTe2O7:Eu3+ (Ln = Y and Gd) phosphors were synthesized using a rapid microwave-assisted solid-state (MASS) method to fulfill these applications. Under 395 nm excitation, NaLnTe2O7:Eu3+ exhibit the characteristic 5D0→7FJ (J = 1–4) transitions of Eu3+. Substituting Gd3+ for Y3+ enhances the luminescence by approximately 2.42 times. Structural analyses reveal that the improved luminescent properties are attributed to the more distorted and appropriate coordination environment in NaGdTe2O7:Eu3+. Finally, white-LEDs using NaGdTe2O7:Eu3+ as the red-component produce white light with high Ra of 89. Furthermore, the distinct thermal responses of the 5D0 → 7FJ transitions enable NaLnTe2O7:Eu3+ to function as temperature sensors via fluorescence intensity ratio (FIR) strategy. NaYTe2O7:Eu3+ possesses the maximum relative/absolute sensitivity of 1.45%/15.93% K−1, whereas NaGdTe2O7:Eu3+ achieves the maximum relative/absolute sensitivity of 1.53%/30.24% K−1.

Traditionally, strategies for designing high-performance birefringent crystals have focused on modifying the parent structure. However, there are limited examples demonstrating how changing functional groups can effectively enhance birefringence (Δn), as such changes often significantly alter the crystal structure. In this study, we propose a “functional group implantation” strategy aiming at significantly improving birefringent performance within the chalcogenide system. This involves replacing the isotropic [S]2– ions with anisotropic π-conjugated [CO3]2– groups. We validated this approach through comprehensive comparisons between the chalcogenide [Ba3S][GeS4] and oxychalcogenide [Ba3CO3][MS4] (M = Ge and Sn), both of which adopt the same space group and feature the same arrangements of functional groups. Experimental characterization and theoretical calculations confirm that the [CO3]2– groups exhibit significantly greater polarization anisotropy than the [S]2– groups. This difference leads to a marked increase in Δn in [Ba3CO3][MS4] (ranging from 0.088 to 0.112 at 546 nm) compared to [Ba3S][GeS4] (0.021 at 546 nm). This finding not only broadens the structural chemistry of π-conjugated chalcogenides but also illustrates the potential of functional group implantation for designing infrared birefringent crystals with enhanced optical anisotropy.</div></div>","PeriodicalId":10151,"journal":{"name":"结构化学","volume":"44 1","pages":"Article 100455"},"PeriodicalIF":5.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
