    The synthesis of 4′-aryl substituted terpyridines by Suzuki cross-coupling reactions: substituent effects on ligand fluorescence
    摘要:
    通过钯催化的交叉偶联反应,制备了几种4′-芳基取代的2,2′:6′,2″-三联吡啶(tpy-C6H4R),涉及4′-溴三联吡啶或4′-三氟甲磺酸酯三联吡啶(triflate = 三氟甲磺酰氧基)与芳基硼酸或硼酸酯的反应,RC6H4B(OR′)2(R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2)。新配体4′-三甲基苯基三联吡啶(mesityl = 2,4,6-三甲基苯基)也通过相同方法制备。类似地,4′-溴苯基三联吡啶(tpy-Φ-Br)已与芳基卤化物交叉偶联,生成了几种新的双芳基取代三联吡啶(tpy-Φ-C6H4R,其中R = H, p-CN, NMe2, NPh2),以及两种含有3-或4-吡啶基侧链的相关化合物(tpy-Φ-C6H4-py)。对于选定的化合物,还研究了替代的偶联策略,即反应一个三联吡啶-4-硼酸酯或三联吡啶-4-苯基硼酸酯与适当的芳基卤化物(例如制备tpy-Φ-C6H4NO2),但通常发现效果较差。所有化合物在紫外区域都有荧光发射,双芳基取代的化合物相比于单芳基系统仅有轻微的红移,但其伴随质子化产生的进一步红移对前者更为显著。溶液中的荧光寿命在1~5纳秒范围内。氨基联苯取代化合物的发射光谱(tpy-Φ-C6H4NR″2,其中R″ = Me或Ph)随着溶剂极性的增加显示出较大的红移,表明存在分子内电荷转移态,这与先前报道的两种省略苯环的类似物(tpy-C6H4NR″2)一致。然而,与后者不同,氨基联苯化合物在质子化或与路易斯酸性金属离子结合时,其发射几乎完全淬灭。

    The synthesis, photophysical properties and water oxidation studies of a series of novel photosensitizer–catalyst assemblies
    摘要:
    A novel series of bridging ligands and their Ru-II photosensitizer-catalyst dyads have been prepared and characterized by NMR and electronic absorption spectroscopy as well as cyclic voltammetry. The presence of asymmetry in the ligands facilitated selective metal coordination, which greatly enhanced the ease of the preparation of the dyads. The photophysical properties of the photosensitizers and the photosensitizer-catalyst dyads were also studied. All the photosensitizers were found to be strong emitters while the extremely weak emission of the dyads suggested quenching by either energy or electron transfer. The water oxidation activities of the dyads have been evaluated under both light and Celv activated conditions. The dyads were found to be active under Celv activated conditions. Electrochemical studies also suggest that these systems may be used as electrocatalysts for photoelectrochemical water oxidation. (C) 2016 Elsevier B.V. All rights reserved.

  • BODIPY-Based Ratiometric Fluoroionophores with Bidirectional Spectral Shifts for the Selective Recognition of Heavy Metal Ions

    Two novel asymmetric BODIPY fluoroionophores with dipicolylamine (BDP-DPA, dipicolylamine: bis(pyridylmethyl)) and terpyridine (BDP-TPY) are described. These fluoroionophores display opposite wavelength responses on complexation with heavy metal ions. Furthermore, the fluorescence spectra vary depending on the ionic species. In particular, BDP-DPA shows a high affinity toward Cr3+ and upon complexation, the fluorescence spectrum blue-shifts from 591 to 566 nm. In contrast, BDP-TPY preferentially binds to Zn2+ and the fluorescence spectra red-shifts from 539 to 567 nm. BDP-TPY is the first example of asymmetric BODIPY with a pyridyl receptor at the 3 position showing red-shifted fluorescence by complexation with metal ions. The concentration of each metal ion was successfully determined by ratiometric measurement. The wavelength-responses characteristics of these fluoroionophores could be very useful in the development of novel ratiometric fluoroionophores for metal ions.
    描述了两种新型非对称BODIPY荧光离子载体,分别为二吡啶基胺(BDP-DPA,二吡啶基胺:双(吡啶甲基))和三吡啶(BDP-TPY)。这些荧光离子载体在与重金属离子形成配合物时显示出相反的波长响应。此外,荧光光谱根据离子种类的不同而变化。特别地,BDP-DPA对Cr³⁺具有较高的亲和力,配合后荧光光谱从591 nm蓝移至566 nm。相比之下,BDP-TPY更倾向于与Zn²⁺结合,荧光光谱则从539 nm红移至567 nm。BDP-TPY是第一个在3位具有吡啶受体的非对称BODIPY,通过与金属离子配合显示红移荧光的例子。每种金属离子的浓度都通过比率测量成功确定。这些荧光离子载体的波长响应特性在开发新型金属离子比率荧光离子载体时可能非常有用。

    Synthesis, redox, spectroscopic, and photophysical properties of a new class of Pt(II) complexes of the type [PtLnCl]+ are reported, where Ln is 4'-phenyl(dimesitylboryl)-2,2':6',2"-terpyridine (L1) or 4'-duryl(dimesitylboryl)-2,2':6',2"-terpyridine (L2). The free L1 or L2 ligand in CH3CN shows the absorption band responsible for intramolecular charge transfer (CT) from the pi-orbital of the aryl group

    related complex [Ru(ttpy)L4]2+ (L4  = terpyridine-4′-boronic acid) could not be prepared, either directly from L2 or from [Ru(ttpy)(tpy-Br)]2+, apparently due to competitive hydrodeboration and solvolysis. The complex [Ru(ttpy)L3]2+ reacts with aryl halides under standard palladium-catalysed Suzuki–Miyaura cross-coupling conditions to generate more elaborate 4′-aryl-substituted terpyridyl complexes.

    reported dyad, 1. The molecular dyads 2–4 have been designed to have their (potentially emissive) triplet metal-to-ligand charge-transfer (MLCT) and charge-separated (CS) states close in energy, so that excited-state equilibration between these levels can take place. Such a situation is not shared by limit cases 1 and 5. For dyad 1, forward photoinduced electron transfer (time constant, 7 ps) and subsequent
