  HOMO and LUMO energy levels of N,N′-dinitrophenyl-substituted polar diketopyrrolopyrroles (DPPs)

  摘要：

  A series of four [3,4-c]pyrrole-1,4-diones (diketopyrrolopyrroles, DPPs) with (substituted) phenyl rings in 3,6-positions was prepared by direct N,N'-arylation of corresponding diketopyrrolopyrrole pigments with 1-fluoro-2,4-dinitro-benzene. While the energies of the HOMO levels depend strongly on the nature of the p-substituehts on the 3,5-phenyl rings, the LUMO levels obtained by cyclic and rotating disc voltammetry were found to be almost independent of the substituent. The absorption spectra show either a hypsochromic or bathochromic shift with respect to parent pigments, depending on the electron-donating and -accepting character of the p-substituents. This behaviour was rationalized by density functional theory calculations, showing that highest occupied molecular orbital is delocalized over the whole 3,6-diphenyl-diketopyrrolopyrrole conjugated system as in the parent pigments, while low-lying LUMO is completely different from the precursors, as it is localized exclusively on the 2,4-dinitrophenyl substituents, i.e. its shape and energy are not affected by a substitution on the 3,6-phenyl rings.

  Novel, soluble diphenyl-diketo-pyrrolopyrroles: Experimental and theoretical study

  摘要：

  Derivatives of diphenyl-diketo-pyrrolopyrrole, possessing electron-donating or withdrawing groups in the p-position of the phenyl, were synthesized and studied using optical characterization (absorption, fluorescence, time-resolved fluorescence) and quantum chemical calculation. An increase in absorption coefficient >= 10(5) dm(3) mol(-1) cm(-1) was observed using electron-donor groups; a bathochromic shift in both absorption and luminescence peaks was observed as a result of increased conjugation. Soluble derivatives were obtained by the introduction of alkyl groups (by N-alkylation) in the central pyrrolopyrrole unit. Calculated phenyl torsion angles using HF and B3LYP methods showed that the loss of molecule planarity reduced the extent of overlap between the pi-orbitals of the central pyrrolopyrrole unit and phenyls after N-alkylation. This treatment thus reduced both the bathochromic shift and increased absorption coefficient. The presence of the donor or acceptor groups in itself does not influence molecule planarity.

  formation reaction with heteroaromatic amines is a highly potential chromophore due to its intense absorption and fluorescence in the visible region and high fluorescence quantum yield, which is greater than 0.8. To control the absorption and fluorescence of PPAB, particularly in the near‐infrared (NIR) region, further molecular design was performed using DFT calculations. This results in the postulation

  吡咯并吡咯氮杂在我们最近的研究中开发的‐BODIPY（PPAB）是由二酮吡咯并吡咯通过四氯化钛介导的与杂芳族胺的席夫碱形成反应形成的发色团，由于其在可见光区的强烈吸收和荧光作用以及较高的荧光量子产率，因此是一种潜在的发色团。大于0.8。为了控制PPAB的吸收和荧光，特别是在近红外（NIR）区域，使用DFT计算进行了进一步的分子设计。这导致假设，杂芳族部分和芳基取代基干扰了PPAB的HOMO-LUMO间隙。基于这种分子设计，合成了一系列新的PPAB分子，其中最大吸收红移和荧光最大值分别高达803和850 nm，对于由苯并噻唑环和叔噻吩基取代基组成的PPAB，获得了相同的收率。与PPAB的急剧吸收相反，通过PPAB单体的交叉偶联反应制得的PPAB二聚体在UV / Vis / NIR区域表现出全色吸收。有了这一系列的PPAB生色团，人们研究了PPAB作为光电材料的潜在应用。根据使用时间分辨的微波

  Six soluble derivatives of 3,6-diphenyl-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione N-alkylated on pyrrolinone ring with polar substituents in para positions of pendant phenyl rings were synthesized: five of them are reported for the first time. Absorption and fluorescence spectra were studied in solvents of different polarity. The compounds show small solvatochromism of absorption and a moderate positive solvatochromism of fluorescence, especially when substituted by strong electron-donating piperidino substituent. A significant decrease of fluorescence quantum yields and its biexponential decay for dipolar derivatives in polar solvents was tentatively ascribed to the formation of twisted intramolecular charge transfer (TICT) excited state. All six compounds show fluorescence in polycrystalline solid-state with the maxima covering a range over 200 nm in visible and near infrared region. (C) 2011 Elsevier Ltd. All rights reserved.
