    Diels–Alder将各种亲二烯体环加成至多环芳烃(PAH)的海湾区域是一种特别有效的工具,可用于修饰PAHs的结构及其最终性能。Diels-Alder环加成反应属于单步环式π扩展(APEX)反应,代表了π扩展的PAH(包括官能化的,纳米石墨烯和π扩展的稠合杂芳烃)的合成效率的最大值。本文中,我们报告了APEX策略在合成1,2-二芳基苯并per,1,2-二芳基苯并per双亚胺和1,2-二取代-苯并[j]并列烯的衍生物中的新应用。即,使用了迄今未知的1,2-二芳基乙炔向the和per双酰亚胺海湾区域的环加成反应。1,通过使用新型高效的苯生成和/或高压条件系统,将苯炔环加成成1,2-二芳基苯并g萘,可制得2-二取代苯并[j]氢酮。此外,我们报道了1,4-(9,9-二烷基芴-3-基)-1,3-丁二炔与per之间空前的Diels-Alder环加成-环芳构化多米诺型反应。通过DFT计算以及电化学和

  • Tuning the photophysical properties of N^N Pt(ii) bisacetylide complexes with fluorene moiety and its applications for triplet–triplet-annihilation based upconversion

    日期:——
    Fluorene-containing aryl acetylide ligands were used to prepare N^NPt(II) bisacetylide complexes, where aryl substituents on the fluorene are phenyl (Pt-1), naphthal (Pt-2), anthranyl (Pt-3), pyrenyl (Pt-4), 4-diphenylaminophenyl (Pt-5) and 9,9-di-n-octylfluorene (Pt-6) (where N^N ligand = 4,4′-di-tert-butyl-2,2′-bipyridine, dbbpy). All the complexes show room temperature (RT) phosphorescence. The emissive T1 excited states of Pt-1, Pt-5 and Pt-6 were assigned as metal-to-ligand-charge-transfer state (3MLCT), whereas for Pt-2, Pt-3 and Pt-4, the emissive T1 excited states were identified as the intraligand state (3IL), based on steady state emission spectra, the lifetime of the T1 state, emission spectra at 77 K, spin density analysis and the time-resolved transient absorption spectroscopy. Exceptionally long lived T1 excited state was observed for Pt-3 (τ = 66.7 μs) and Pt-4 (τ = 54.7 μs), compared to a model complex dbbpy Pt(II) Bisphenylacetylide (τ = 1.25 μs). RT phosphorescence of anthracene was observed at 780 nm with Pt-3. The critical role of the fluorene is to move the absorption of the complexes to the red-end of the spectra, but at the same time, without compromising the energy level of the T1 state of the complexes. The advantage of this unique spectral tuning effect and the long-lived T1 excited states of Pt-4 was demonstrated by the enhanced performance of the complexes as triplet sensitizers for triplet–triplet annihilation (TTA) based upconversion; an upconversion quantum yield (ΦUC) up to 22.4% was observed with Pt-4 as the sensitizer. Other complexes described herein show negligible upconversion. The high upconversion quantum yield of Pt-4 is attributed to its intense absorption of visible light and long-lived T1 excited state. Based on the result of Pt-4, we propose that weakly phosphorescent, or non-phosphorescent transition metal complexes can be used as triplet sensitizers for TTA upconversion, compared to the phosphorescent triplet sensitizers currently used for TTA upconversion. Our results will be useful for the design of transition metal complexes to enhance the light-absorption and thereafter the cascade photophysical processes, without decreasing the T1 excited state energy levels, which are important for the application of the complexes as triplet sensitizers in various photophysical processes.
    含氟苯的芳香烃乙炔配体被用于制备N^NPt(II)双乙炔配合物,其中氟苯上的芳香取代基为酚基(Pt-1)、萘基(Pt-2)、蒽基(Pt-3)、芘基(Pt-4)、4-二苯胺苯基(Pt-5)和9,9-二正辛基氟苯(Pt-6)(其中N^N配体为4,4' -二叔丁基-2,2' -联吡啶,dbbpy)。所有配合物在室温下均显示出磷光。通过稳态发射光谱、T1态的寿命、77K下的发射光谱、自旋密度分析和时间分辨瞬态吸收光谱法,将Pt-1、Pt-5和Pt-6的发射性T1激发态归类为金属-配体电荷转移态(3MLCT),而Pt-2、Pt-3和Pt-4的发射性T1激发态则被鉴定为配体内态(3IL)。Pt-3(τ = 66.7μs)和Pt-4(τ = 54.7μs)显示出异常长寿命的T1激发态,相较于模型配合物dbbpy Pt(II)双苯乙炔(τ = 1.25μs)。观察到Pt-3在780nm处有蒽的室温磷光。氟苯的关键作用是将配合物的吸收移至光谱的红端,同时不降低配合物T1态的能级。这种独特的光谱调谐效应以及Pt-4的长寿命T1激发态的优势,通过配合物在三重态-三重态湮灭(TTA)基础上的上转换作为三重态敏化剂的增强性能得以体现;观察到Pt-4作为敏化剂的上转换量子产率(ΦUC)高达22.4%。其他在此描述的配合物几乎没有上转换。Pt-4高上转换量子产率的原因在于其对可见光的强吸收和长寿命的T1激发态。基于Pt-4的结果,我们提出弱磷光或非磷光的过渡金属配合物可以用作TTA上转换的三重态敏化剂,相较于目前用于TTA上转换的磷光三重态敏化剂。我们的结果将有助于设计过渡金属配合物,以增强光吸收及其后的级联光物理过程,同时不降低T1激发态能级,这对这些配合物在各种光物理过程中的应用作为三重态敏化剂至关重要。

    A series of trimethylsilyl-protected and terminal mono- and bis-alkynes based on 9,9-dioctylfluorene, 2-(trimethylsilylethynyl)-9,9-dioctylfluorene 1a, 2-ethynyl-9,9-dioctylfluorene 1b, 2,7-bis(trimethylsilylethynyl)-9,9-dioctylfluorene 2a, 2,7-bis(ethynyl)-9,9-dioctylfluorene 2b, have been synthesised. Reaction of trans-[(PnBu3)2PtCl2] with 2 equivalents of the terminal ethyne 1b yields the mononuclear platinum(II) diyne 3, reaction of trans-[(Ph)(Et3P)2PtCl] with 0.5 equivalents of the diterminal ethyne 2b gives the dinuclear platinum(II) diyne 4 while 1 ∶ 1 reaction between trans-[(PnBu3)2PtCl2] and 2b gives the platinum(II) poly-yne 5. Treatment of 2,5-dioctyloxy-1,4-diiodobenzene with 1b in 1 ∶ 2 stoichiometry produces the organic di-yne 6 while 1 ∶ 1 reaction between 2,5-dioctyloxy-1,4-diiodobenzene and 2b, 2,7-bis(ethynyl)fluorene or 2,7-bis(ethynyl)fluoren-9-one produces the organic co-poly-ynes 7–9. All the new materials have been characterised by analytical and spectroscopic methods and the single crystal X-ray structures of 2a and 3 have been determined. The diynes and poly-ynes are soluble in organic solvents and are readily cast into thin films. Optical spectroscopic measurements reveal that the attachment of octyl side-chains on the fluorenyl spacer reduces inter-chain interaction in the poly-ynes while a fluorenonyl spacer creates a donor–acceptor interaction along the rigid backbone of the organometallic poly-ynes and organic co-poly-ynes.
