摘要:碳点(CDs)因低毒性、小尺寸、可降解、荧光可调、强光吸收和优异光稳定性成为有前景的碳基纳米材料,应用从生物成像到光电显示。然而,将溶液相光致发光转化为高效固态发射仍具挑战,因为聚集导致猝灭、光谱展宽、表面态异质性和非辐射损失会损害色纯度和发射效率。本综述总结固态多色 CDs 用于光电显示的最新进展,关注合成策略及分子前驱体、溶剂、反应条件、杂原子掺杂和表面钝化对发射性质影响。比较蓝、绿、黄/橙、红/NIR 发射 CDs 的光谱带宽、PLQY 和固态性能。讨论抑制 ACQ 的基质工程、主–客体限域、表面分子设计、AIE 和激发态调控策略,并总结其在颜色转换背光、LCD/mini-LED、柔性电致发光器件中的集成,最后与 OLED、QLED、PeLED 基准比较。

摘要:聚集诱导白光发射(AIWE)OLED 可规避多发射体架构的电致发光光谱不稳定和制造复杂性,是下一代显示与照明有吸引力平台。本文报道基于 AIWE 体系实现光谱稳定白光 EL 的新策略,白光不依赖传统单分子发射,而来自单组分 TADF 发射体的聚集诱导白光发射。设计分子 2tCz-2tBO 由平面供体和两个多共振受体经螺芴连接形成近平行 A–D–A 构型,强制供受体空间分离,促进高效多重空间电荷转移(TSCT)。该材料在聚集态可同时蓝光和黄光发射。优化白光 OLED 最大外量子效率 8.4%,并在工作电压范围内保持光谱稳定白光。

High‐Performance Narrowband Green OLEDs Enabled by Indolocarbazole Isomer Engineering and Steric Shielding#

摘要:符合 BT.2020 标准的发射体对超高清显示至关重要,但同时实现高效率和高色纯度绿色 MR-TADF 发射体仍具挑战。本文通过 ICz 异构体工程与外周位阻屏蔽结合的分子工程策略,开发两种窄带绿光 MR-TADF 发射体 Mes-b-ICzBN 和 Mes-c-ICzBN。二者融合刚性吲哚并咔唑(ICz)片段并引入大位阻均三甲苯基;ICz 扩展 MR 框架并限制结构弛豫,均三甲苯基最小化聚集诱导光谱展宽。ICz 异构工程可精细调节发射峰,使窄带绿光更接近 BT.2020 绿色标准。相应 OLED 的 CIE 坐标分别为 (0.25, 0.70) 和 (0.22, 0.71),FWHM 26 nm 和 27 nm,最大外量子效率 33.3% 和 30.6%。与背板驱动集成构建 AM OLED 面板,并演示高动态范围 pico-projector 原型。

Modular synthesis of unsymmetrical all-carbon tetrasubstituted alkenes via pd-catalyzed multi-component coupling#

摘要:四取代烯烃在材料科学、生物医学和化学中是一类优势结构,但实现立体控制合成——尤其含四个不同取代基的分子——仍具挑战。本文报道钯催化三组分级联反应,在一锅中将炔基四配位硼化合物与两种不同芳基卤化物直接偶联。反应先与一种芳基卤化物偶联形成烯基硼中间体,再与另一芳基卤化物进行第二次 Suzuki 型偶联。该策略解决四取代烯烃合成中长期存在的化学选择性和副产物问题,实现不对称四取代烯烃的模块化组装,并可立体定义地获得含四个不同取代基的目标物。反应条件温和、官能团耐受性好、底物范围广(>100 例)。多个衍生物表现 AIE 和固态明显红移,展示固态红发射潜力,并用于简洁合成 Toremifene 和 Tamoxifen。

Development of high-contrast mechanochromic materials based on pyrene-functionalized N,O-bidentate imine BF2 complexes#

摘要:机械变色发光(MCL)材料在外部机械刺激下显示可切换光学行为,在信息存储、防伪和压力传感中潜力大,但高对比 MCL 材料仍具挑战。本文设计合成三种芘功能化 N,O-双齿亚胺 BF₂ 配合物 C-1、C-2 和 C-3。染料在多种溶剂中具有超大 Stokes 位移(一般 >150 nm)并表现 AIE。值得注意的是,C-1 和 C-2 具有高对比可逆 MCL,光谱位移分别为 86 nm 和 63 nm。PXRD 和 DSC 表明研磨诱导晶态向低有序、主要非晶态转变,与红移密切相关;除分子堆积变化外,供体–受体骨架构象弛豫也可能贡献发射变化。

Subtle chemical modification around tetraphenylethylene unit to create opposite emission color shifts in high-contrast mechanofluorochromic properties#

摘要:化学结构微小变化可诱导显著机械荧光变色现象。本文以四苯基乙烯为供体、苯并[b]噻吩-3(2H)-酮 1,1-二氧化物为受体,设计合成两种扭曲 D-A 结构 MFC 材料 WS 和 XW。有趣的是,WS 和 XW 分别表现 AIE 和 ACQ。研磨原始样品显示相反发射位移方向和高对比荧光颜色变化:WS 蓝移 18 nm,XW 红移 82 nm。单晶 XRD 表明弱分子间相互作用和 J-聚集模式使 WS 分子堆积更松散,其堆积排列在 MFC 行为下易崩塌。XW 可用于光学记录器件。

Rationally engineering nanoparticle internal structure via flash nanoprecipitation: A millisecond-scale competition between turbulent micromixing and aggregation dynamics#

摘要:闪速纳米沉淀(FNP)结合受限撞击射流微混合是新兴纳米制造方法,可快速连续经济生产高载量纳米悬浮液,但缺乏对颗粒形成竞争动力学过程的定量理解。本文通过建立 FNP 工艺参数(二嵌段共聚物分子量和雷诺数)与纳米颗粒内部结构直接关联,解析湍流微混合(自上而下)与多级聚集动力学(自下而上,包括相分离和分相)之间的竞争。以 AIE 发光原为分子探针,将动力学互溶与相分离内部结构转变映射到聚集特征时间 τagg 与混合特征时间 τmix 之比。该时间尺度判据提供定量选择规则,决定演化路径和最终纳米颗粒尺寸稳定性,为通过 FNP 过程控制合理工程化纳米颗粒内部结构提供机理框架。

摘要:本文报道基于芳香硫醚、具 AIE 性质的肽偶联荧光团,用于小蛋白特异性识别,并获得首个 AIE 配体与蛋白特异性结合的溶液 NMR 结构。以 hPin1-WW 结构域为模型蛋白,结合后荧光显著增强,使 AIE–肽荧光团可作为特异性蛋白相互作用的直接读出探针。阐明了自荧光和蛋白结合性质随肽长度和荧光团浓度的变化。含两条共轭肽的 AIE 荧光团蛋白结合后荧光增强更强;单臂衍生物使作者解析了游离 AIE–肽及其复合物结构。无蛋白时 AIE–肽呈卷曲构象,AIE 核芳环仍可旋转,自荧光低;结合后 AIE–肽展开,hPin1-WW 与肽识别序列作用,AIE 核芳环与蛋白表面额外接触,限制运动并导致荧光增强。
