  Fluorogenic aldehydes bearing arylethynyl groups: turn-on aldol reaction sensors for evaluation of organocatalysis in DMSO

  摘要：

  Fluorogenic aromatic aldehydes bearing arylethynyl groups were developed. They were used for monitoring the reaction progress of organocatalytic aldol reactions in DMSO through an increase in the fluorescence intensity based on the formation of the florescent aldol product. The ratios of the fluorescence intensities of the aldols to the aldehydes were more than 300. These results suggest that the fluorescence assay system using the aldehyde is useful for the rapid identification of superior aldol catalysts and reaction conditions. (c) 2014 Elsevier Ltd.

  anthracene derivatives, but only weak emission was observed for perylene bisimide derivatives. The anthracene derivatives showed typical p-type semiconducting character, even when the derivatives were substituted with electron-withdrawing benzimidazole groups at the 9- and 10-positions, which apparently does not lower the LUMO levels to transform them into electron-transporting molecules.

  设计并制备了一系列具有吸电子苯并咪唑取代基的蒽和苝双酰亚胺衍生物。对这些新化合物的电化学和光物理特性以及场效应迁移率进行了详细研究。与母体化合物相比，吸电子苯并咪唑基团的引入降低了蒽和苝双酰亚胺衍生物中的 LUMO 水平。所有蒽衍生物均观察到强发射，但苝双酰亚胺衍生物仅观察到微弱发射。蒽衍生物显示出典型的 p 型半导体特性，即使这些衍生物在 9 位和 10 位被吸电子苯并咪唑基团取代，这显然不会降低 LUMO 能级以将它们转化为电子传输分子。苝双酰亚胺衍生物显示出典型的 n 通道半导体特性，具有低阈值电压和约 10 倍的电子迁移率。5.2 × 10–5 cm2 V–1 s–1。

  A series of anthrylpolyynes (α-anthryl-ω-(formylphenyl)polyynes) and anthrylpolyynylporphyrins (5-[(anthrylpolyynyl)phenyl]porphyrins) have been synthesized, and their photochemical properties and photoinitiated intramolecular excitation energy transfer from anthracene to porphyrin were studied by picosecond time-resolved fluorescence spectroscopy. Although anthrylpolyynes have strong fluorescence emission and fluorescence high quantum yield, anthrylpolyynylporphyrins, in which porphyrin links to the other side of polyyne, show only typical fluorescence emission of porphyrin and almost no fluorescence emission in the spectral region of anthrylpolyynes. The excitation of anthryl substituent brings about an increase in the fluorescence emission of porphyrin on the picosecond time scale. The mechanism of quantitative energy transfer from the anthryl moiety to the porphyrin is discussed on the basis of the photochemical properties of the component molecules.

  合成了一系列蒽基多炔(α-蒽基-ω-(甲酰基苯基)多炔)和蒽基多炔基卟啉(5-[(蒽基多炔基)苯基]卟啉)，并研究了它们的光化学性质和从蒽到卟啉的光引发分子内激发能量转移。皮秒时间分辨荧光光谱。尽管蒽基多炔具有较强的荧光发射和较高的荧光量子产率，但卟啉与多炔的另一侧连接的蒽基多炔基卟啉仅表现出卟啉的典型荧光发射，而在蒽基多炔的光谱区几乎不发射荧光。蒽基取代基的激发导致卟啉在皮秒时间尺度上的荧光发射增加。基于组成分子的光化学性质，讨论了从蒽基部分到卟啉的定量能量转移的机制。
