Nonetheless, the current strategies still face some pressing issues. Herein, we demonstrate a novel synergistic strategy of carbon nitride (C₃N₃) as a buried modified layer and a perovskite antisolvent additive to reduce energy loss resulting from nonradiative recombination. C₃N₃ functions serve as an interfacial modification layer that enhances electron mobility, improves interface contacts, and matches energy levels between SnO₂ and perovskite. Meanwhile, C₃N₃ acts as an antisolvent additive in the perovskite layer, reducing defect density and modulating the energy level, which boosts both the efficiency and moisture stability of PSCs. Consequently, the target devices achieve a remarkable power conversion efficiency of 21.43%, with unencapsulated devices retaining 90% of their initial value after operating 1000 h. These integrated strategies provide a promising method for simultaneously reducing interfacial and bulk defects, with potential application in other photoelectronic devices.","PeriodicalId":5,"journal":{"name":"ACS Applied Materials & Interfaces","volume":"216 1","pages":""},"PeriodicalIF":9.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these interactions often lack robustness in the presence of blood proteins due to the competitive binding of blood proteins, which results from strong π-π-stacking interactions with aromatic protein residues. This can lead to premature drug release and diminished therapeutic efficacy. To address this challenge, we developed a robust 2D delivery/therapeutic biomimetic nanoplatform that enhances the adsorption affinity and targeted delivery efficiency of the chemotherapeutic drug doxorubicin (DOX) by utilizing Cu²⁺-modified black phosphorus nanosheets (BP@Cu²⁺) through metal ion-assisted π-π interactions. The synergistic interactions between the π-electrons of BP and DOX, mediated by Cu²⁺ coordination, form a stable sandwiched π-cation-π stacking complex (BP@Cu²⁺/DOX). This metal-ion-bridged architecture significantly enhances the DOX loading capacity and minimizes premature release in serum. In the acidic tumor microenvironment, this interaction is disrupted, enabling controlled release of both DOX and Cu²⁺ ions. Furthermore, the encapsulation of the complex within tumor cell membranes significantly enhances the efficiency of tumor targeting, resulting in a biomimetic nanoplatform (BP@Cu²⁺/DOX-CMs). Combined with near-infrared laser irradiation, this nanoplatform achieves synergistic multimodal therapy by integrating phototherapy, chemotherapy, chemodynamic therapy, and cuproptosis to enhance antitumor efficacy.

However, the efficiency and stability of these Sn-PSCs that utilize PEDOT:PSS are unsatisfactory, partly due to concerns about their mismatched work functions, hydrophobicity, and chemical interactions. Here, we introduce a self-assembled monolayer (SAM), (2-(7<i>H</i>-dibenzo[c,g]carbazol-7-yl)ethyl) phosphonic acid (2PADCB) as a multifunctional buffer molecule at the buried PEDOT:PSS/Sn perovskite interface. The phosphate group in the 2PADCB molecule reacts with the sulfur atom on the thiophene ring in PEDOT:PSS. This reaction process effectively anchors the SAM molecule firmly to the surface of PEDOT:PSS. Additionally, it reduces the binding sites between PEDOT and PSS, alleviating the acidification of the PEDOT:PSS surface and the poor conductivity caused by excessive PSS. Furthermore, the presence of two additional benzene rings in the 2PADCB molecule terminal group increases the electron density around Sn²⁺, thereby inhibiting its oxidation. Additionally, the hydrophobic characteristics of the 2PADCB molecule mitigate moisture infiltration from PEDOT:PSS, thereby protecting the degradation of Sn perovskite. Consequently, the Sn-PSCs based on the PEDOT:PSS/2PADCB film achieve a champion efficiency of 14.7%, higher than that of their pristine counterpart (12.5%). Moreover, the 2PADCB molecule improves the stability of the device by maintaining 90% of its initial efficiency after 160 h under 1 Sun illumination. Such enhancement in efficiency and stability is mainly attributed to the improved interface quality with the 2PADCB molecule, leading to better carrier transport and suppressed charge recombination at the buried PEDOT:PSS/Sn perovskite interface.
