    Synthesis and characterization of photoresponsive diphenylaminofluorene chromophore adducts of [60]fullerene
    摘要:
    合成了一类接受体-酮-供体结构,包括受阻的9,9-二(3,5,5-三甲基己基)-2-二苯胺氟烯-美琅[60]富勒烯C60(>DPAF-C9)及相关的双加合物C60(>DPAF-C9)2和C60(>DPAF-C2)2。它们是多光子吸收C60(>DPAF-C2)的衍生物,在激光激发下800 nm的纳秒区域显示出增强的同时两光子吸收截面。这些C60-DPAF共轭物的分子合成涉及通过酮联结将二苯氨基氟烯部分共价连接到美琅[60]富勒烯上,以增加分子的接受体-供体极性,与富勒烯笼体结合。7-(1,2-二氢-1,2-美琅富勒烯[60]-61-羰基)-9,9-二烷基-2-二苯胺氟烯C60(>DPAF-Cn)的制备涉及用关键合成单元7-α-溴乙酰-9,9-二烷基-2-二苯胺氟烯对C60进行环丙烷化。该合成单元的合成通过三步法实现,起始于2-溴氟烯,通过对氟烯环的C9位的双烷基化,在双烷基氟烯的C2位上连接二苯胺基团,以及在二苯胺氟烯的C7位对α-溴乙酰基进行弗riedel-Craft酰化。所有C60-DPAF衍生物均经过全面表征,化学结构通过各种光谱分析确认,并通过C60(>DPAF-C2)的单晶结构分析数据进行验证。观察到C60(>DPAF-C2)、C60(>DPAF-C9)和C60(>DPAF-C9)2的强溶剂敏感荧光猝灭现象,在更极性溶剂(如DMF、PhCN和THF)中未观察到700 nm以上的荧光带,而在较少极性的溶剂(如甲苯、CHCl3和CS2)中观察到700-710 nm的富勒烯荧光带。这归因于在前一组溶剂中,通过富勒烯部分的单态激发态1C60*(>DPAF-Cn)发生电子转移。相反,在后者溶剂组中,DPAF-Cn部分向富勒烯笼体的能量转移过程更加有利。

    Synthesis and Photoluminescent Properties of Geometrically Hindered cis-Tris(diphenylaminofluorene) as Precursors to Light-Emitting Devices
    摘要:
    以 C3 对称三氨基苯为核心合成了一种新型高发光三芴环互连发色团 tris(DPAF-C9)。这种结构包含三个采光的 2-二苯基氨基-9,9-二烷基芴(DPAF)环分子,每个环分子由两个支化的 3',5',5'-三甲基己基(C9)臂连接。经色谱分离和表征,其中一种主要的立体异构体具有杯状顺式的三维结构构型。B3LYP/6-31G* 级分子计算显示,三(DPAF-C9)的顺式杯形构象具有出乎意料的稳定性,其稳定性优于螺旋桨形立体异构体和反式构象。该结构几何形状被认为能够最大程度地降低凝聚相中与聚集相关的自淬效应。研究发现,三(DPAF-C9)的荧光发射波长与 PVK 的荧光发射波长相近,因此有可能被用作二级蓝洞传输材料,用于提高器件性能,从而调节聚光发光二极管的性能。

    We designed and synthesized several nanomaterials 3 of three-layered core-shell (γ-FeOx@AuNP)@[C60(>DPAF-C9)1or2]n nanoparticles (NPs). These NPs having e−-polarizable fullerosome structures located at the outer layer were fabricated from highly magnetic core-shell γ-FeOx@AuNPs. Fullerosomic polarization of 3 was found to be capable of causing a large amplification of material permittivity that is also associated with the photoswitching effect in the frequency range of 0.5‒4.0 GHz. Multilayered synthetic construction allows Förster resonance energy transfer (FRET) of photoinduced accumulative surface plasmon resonance (SPR) energy in the gold layer to the partially bilayered C60(>DPAF-C9)1or2-derived fullerosome membrane shell layer in a near-field of direct contact without producing radiation heat, which is commonly associated with SPR.

  • Large concentration-dependent nonlinear optical responses of starburst diphenylaminofluorenocarbonyl methano[60]fullerene pentads

    We demonstrate an approach toward the design of starburst C60-keto-DPAF assembly by applying a starburst macromolecular configuration with C60 as the core center, which is encapsulated by multiple bulky groups leading to the increase of intermolecular separation and aggregation barrier. Molecular compositions of the resulting C60(>DPAF-C9)2 triad and C60(>DPAF-C9)4 pentads were clearly confirmed by MALDI-MS (positive ion) detection of protonated molecular mass ions. Both C60(>DPAF-C9)22 and C60(>DPAF-C9)4 (structural isomers, 3a and 3b) exhibited nonlinear optical transmittance reduction responses in the femtosecond (fs) region with a lower transmittance value for the latter at the high laser power above 80 GW cm−2. This was attributed to the larger fs 2PA cross-section values of 3a and 3b than that of 2 at the same concentration and, apparently, correlated to a higher number of DPAF-C9 subunits in the structure of 3. As the concentration was decreased to 10−4 M, a clear monotonous increase of the σ2 value change (Δσ2) from 13.9, 33.2, to 48.1 and 68.2 × 10−48 cm4 s photon−1 molecule−1 (or 6820 GM for the latter) for the structural variation from the monoadduct 1, bisadduct 2, to tetraadducts 3b and 3a, respectively, was observed. We interpreted the concentration-dependent phenomenon as being due to the high tendency of fullerene-DPAF chromophores to form nanoscale aggregates at concentrations above 10−3 M. We also proposed that starburst structures, as exemplified by C60(>DPAF-C9)4, in a multipolar arrangement resembling encapsulation of C60 by DPAF-C9 pendants, provide a useful means to increase the degree of molecular dispersion and maintain high nonlinear optical efficiency.
