Tuning the Absorption, Fluorescence, Intramolecular Charge Transfer, and Intersystem Crossing in Spiro[fluorene]acridinone
Researchers from FAU Solar and the Nanjing University of Posts and Telecommunications provide important guidance for designing novel functional materials for triplet sensitizers and fluorescent sensors. Intersystem crossing is a significant photophysical process in organic molecular systems on the way to create a triplet excited state, which is the cornerstone of photo-catalysis, photo-upconversion, oxygen sensing, […]Researchers from FAU Solar and the Nanjing University of Posts and Telecommunications provide important guidance for designing novel functional materials for triplet sensitizers and fluorescent sensors.

Tuning the Absorption, Fluorescence, Intramolecular Charge Transfer, and Intersystem Crossing in Spiro[fluorene]acridinone
Bo, Y., Zhang, H., Li, Y., Reva, Y., Xie, L., Guldi, D.M. Angewandte Chemie, 136(13), e202313936 In this work, we prepared a series of electron donor-acceptor systems based on spiro[fluorene-9,7’-dibenzo[c,h]acridine]-5’-one (SFDBAO). Our SFDBAOs consist of orthogonally positioned fluorenes and aromatic ketones. By fine-tuning the substitution of electron-donating pyrenes, the complex interplay among different excited-state decay […]Bo, Y., Zhang, H., Li, Y., Reva, Y., Xie, L., Guldi, D.M.

An insight into a combined effect of backsheet and EVA encapsulant on field degradation of PV modules
Buerhop, C., Pickel, T., Stroyuk, O., Hauch, J., Peters, I. M., Energy Science & Engineering 2023, 11, 4168-4180. https://doi.org/10.1002/ese3.1572 Polymer components, in particular, backsheets (BSs) and ethylene-vinyl acetate (EVA) encapsulants, play a crucial role in the degradation of commercial silicon photovoltaic (PV) modules. Degradation mechanisms depend in a complex way on the composition and properties […]Buerhop, C., Pickel, T., Stroyuk, O., Hauch, J., Peters, I.
