Palladium-Catalyzed Cyclization of a Pyryne Precursor to Higher Pyrenylenes [Data]
Aug 23, 2023 - Institute of Organic Chemistry - AK Mastalerz
Popp, Dennis; Elbert, Sven Michael; Barwig, Chantal; Petry, Julian; Rominger, Frank; Mastalerz, Michael, 2023, "Palladium-Catalyzed Cyclization of a Pyryne Precursor to Higher Pyrenylenes [Data]", https://doi.org/10.11588/data/1TCKKG, heiDATA, V1
By palladium-catalyzed oligomerization reactions of pyrene-based o-trimethylsilyl triflates, larger cyclic pyrenylenes were formed with up to 10-membered rings as has been unambiguously characterized by SCXRD. Furthermore, the underlying reaction mechanism has been studied by qua...
Single Crystals of Insoluble Porous Salicylimine Cages [Data]
Aug 23, 2023 - Institute of Organic Chemistry - AK Mastalerz
Holsten, Mattes; Elbert, Sven Michael; Rominger, Frank; Zhang, Wen-Shan; Schröder, Rasmus R.; Mastalerz, Michael, 2023, "Single Crystals of Insoluble Porous Salicylimine Cages [Data]", https://doi.org/10.11588/data/45FZRY, heiDATA, V1
Porous organic cages (POCs) are meanwhile an established class of porous materials. Most of them are soluble to a certain extend and thus processable in or from solution. However, a few of larger salicylimine cages were reported to be insoluble in any organic solvents and thus ch...
A Series of Soluble Thieno-fused Coronene Nanoribbons of Precise Lengths [Data]
Nov 23, 2022 - Institute of Organic Chemistry - AK Mastalerz
Yang, Xuan; Elbert, Sven Michael; Rominger, Frank; Mastalerz, Michael, 2022, "A Series of Soluble Thieno-fused Coronene Nanoribbons of Precise Lengths [Data]", https://doi.org/10.11588/data/30AOAT, heiDATA, V1
Among graphene nanoribbons (GNRs), reports on coronene-based GNRs were very rare, despite the unique optoelectronic properties of coronene. Herein, the synthesis of a series of structurally precise and soluble thieno-fused coronene nanoribbons (CR-1 to CR-4) with up to four coron...
Highly Selective Adsorption of Perfluorinated Greenhouse Gases by Porous Organic Cages [Data]
Nov 16, 2022 - Institute of Organic Chemistry - AK Mastalerz
Tian, Ke; Elbert, Sven Michael; Hu, Xinyue; Kirschbaum, Tobias; Zhang, Wen-Shan; Rominger, Frank; Schröder, Rasmus R.; Mastalerz, Michael, 2022, "Highly Selective Adsorption of Perfluorinated Greenhouse Gases by Porous Organic Cages [Data]", https://doi.org/10.11588/data/O9I5UP, heiDATA, V1
Anthropogenic greenhouse gases contribute to global warming. Among those gases, perfluorocarbons (PFCs) are thousands to tens of thousands times more harmful to the environment than comparable amounts of carbon dioxide. Till date, materials that selectively adsorb perfluorocarbon...
Synthesis of Large [2+3] Salicylimine Cages with Embedded Metal-Salphen Units [Data]
Jan 24, 2022 - Institute of Organic Chemistry - AK Mastalerz
Uhrmacher, Fabian; Elbert, Sven Michael; Rominger, Frank; Mastalerz, Michael, 2022, "Synthesis of Large [2+3] Salicylimine Cages with Embedded Metal-Salphen Units [Data]", https://doi.org/10.11588/data/LOR2JH, heiDATA, V1
Shape-persistent trinuclear Ni(II)- and Pt(II)-cage compounds with large cavities have been synthesized by using bissalicylaldehyde struts that contain the metal salphen units already. The Pt(II) derivative was investigated by single crystal X-ray diffraction.
Proving Triptycene Homoconjugation with the Same Chromophore but Different Connectivity to the Core [Data]
Jan 20, 2022 - Institute of Organic Chemistry - AK Mastalerz
Elbert, Sven Michael; Kirschbaum, Tobias; Rominger, Frank; Mastalerz, Michael, 2022, "Proving Triptycene Homoconjugation with the Same Chromophore but Different Connectivity to the Core [Data]", https://doi.org/10.11588/data/B1JIFI, heiDATA, V1
Homoconjugation is a phenomenon discussed for various π-systems where classical conjugation is broken by e.g. methylene units but still a stabilization by electronic communication exists. In this respect, triptycene with its rigid C3 symmetric geometry is an ideal scaffold to stu...
A Triptycene-Based Enantiopure Bis(Diazadibenzoanthracene) by a Chirality-Assisted Synthesis Approach [Data]
Jan 19, 2022 - Institute of Organic Chemistry - AK Mastalerz
Wang, Xubin; Kohl, Bernd; Rominger, Frank; Elbert, Sven Michael; Mastalerz, Michael, 2022, "A Triptycene-Based Enantiopure Bis(Diazadibenzoanthracene) by a Chirality-Assisted Synthesis Approach [Data]", https://doi.org/10.11588/data/46LINE, heiDATA, V1
By applying a chirality-assisted synthesis (CAS)approach enantiopure diaminodibromotriptycenes were converted to rigid chiral helical diazadibenzoanthracenes, which show besides pronounced Cotton effects in circular dichroism spectra higher photoluminescence quantum yields as com...
