Determination of Energetic Positions of Electronic States and the Exciton Dynamics in a pi-Expanded N-Heterotriangulene Derivative Adsorbed on Au(111)

Autor: Steidel, Jakob, Michalsky, Ina, Ajdari, Mohsen, Kivala, Milan, Tegeder, Petra

Bridged triarylamines, so-called N-heterotriangulenes (N-HTAs) are promising organic semiconductors for applications in optoelectronic devices. Thereby the electronic structure at organic/metal interfaces and within thin films as well as the electron

Electronic Properties of Interfaces between N-Heterotriangulene Donors and Strong Tetracyanoquinodimethane Acceptors

Autor: Ajdari, Mohsen, Pappenberger, Ronja, Walla, Christian, Michalsky, Ina, Maass, Friedrich, Kivala, Milan, Dreuw, Andreas, Tegeder, Petra

N-heterotriangulenes (N-HTAs) represent a class of functional molecules with high potential for optoelectronic materials, for example as electron donating compounds in donor/acceptor (D/A) systems. The capability of two different N-HTAs, N-HTA 550 an

Influence of Core Substitution on the Electronic Structure of Benzobisthiadiazoles

Autor: Ajdari, Mohsen, Pappenberger, Ronja, Annweiler, Caja, Kaczun, Tobias, Mueller, Leon, Winkelmann, Larissa, Ahrens, Lukas, Bunz, Uwe H. F., Dreuw, Andreas, Tegeder, Petra

Benzobisthiadiazoles (BBTs) are promising organic semiconductors for applications in field effect transistors and solar cells, since they possess a strong electron-accepting character. Thereby the electronic structure of organic/metal interfaces and

Selective neuronal expression of progranulin is sufficient to provide neuroprotective and anti-inflammatory effects after traumatic brain injury

Autor: Sudena Wang, Marc-Philipp Weyer, Regina Hummel, Annett Wilken-Schmitz, Irmgard Tegeder, Michael K. E. Schäfer

Publikováno v: Journal of Neuroinflammation, Vol 21, Iss 1, Pp 1-17 (2024)

Abstract Progranulin (PGRN), which is produced in neurons and microglia, is a neurotrophic and anti-inflammatory glycoprotein. Human loss-of-function mutations cause frontotemporal dementia, and PGRN knockout (KO) mice are a model for dementia. In ad
