Correlated shapeshifting and configurational isomerization † (2024)
Journal Article
Maturi, W., Hussein, B. A., Rylands, M. K., Bismillah, A. N., Wen, Y., Aguilar, J. A., Ayub, R., Rankine, C. D., & McGonigal, P. R. (online). Correlated shapeshifting and configurational isomerization †. Chemical Science, https://doi.org/10.1039/d4sc03699a

Herein we demonstrate that the rapid ‘shapeshifting’ constitutional isomerization of a substituted bullvalene is influenced by the E-to-Z configurational isomerization of a remote carbamate group, giving rise to correlated motion. We find that, while... Read More about Correlated shapeshifting and configurational isomerization †.

Control of Dynamic sp3-C Stereochemistry (2023)
Journal Article
Bismillah, A., Johnson, T., Hussein, B., Turley, A., Saha, P., Wong, H., …McGonigal, P. (2023). Control of Dynamic sp3-C Stereochemistry. Nature Chemistry, 15(5), 615-624. https://doi.org/10.1038/s41557-023-01156-7

Stereogenic sp3-hybridized carbon centres are fundamental building blocks of chiral molecules. Unlike dynamic stereogenic motifs, such as sp3-nitrogen centres or atropisomeric biaryls, sp3-carbon centres are usually fixed, requiring intermolecular re...

Rupturing aromaticity by periphery overcrowding (2023)
Journal Article
Saha, P. K., Mallick, A., Turley, A. T., Bismillah, A. N., Danos, A., Monkman, A. P., …McGonigal, P. R. (2023). Rupturing aromaticity by periphery overcrowding. Nature Chemistry, 15(4), 516-525. https://doi.org/10.1038/s41557-023-01149-6

The balance between strain relief and aromatic stabilization dictates the form and function of non-planar π-aromatics. Overcrowded systems are known to undergo geometric deformations, but the energetically favourable π-electron delocalization of thei...

Extended Conjugation Attenuates the Quenching of Aggregation-Induced Emitters by Photocyclization Pathways (2022)
Journal Article
Turley, A., Saha, P., Danos, A., Bismillah, A., Monkman, A., Yufit, D., …McGonigal, P. (2022). Extended Conjugation Attenuates the Quenching of Aggregation-Induced Emitters by Photocyclization Pathways. Angewandte Chemie International Edition, 61(24), Article e202202193. https://doi.org/10.1002/anie.202202193

Herein, we expose how the antagonistic relationship between solid-state luminescence and photocyclization of oligoaryl alkenes chromophores is modulated by the conjugation length of their alkenyl backbones. Heptaaryl cycloheptatriene molecular rotors... Read More about Extended Conjugation Attenuates the Quenching of Aggregation-Induced Emitters by Photocyclization Pathways.

Excited-State Aromatic Interactions in the Aggregation-Induced Emission of Molecular Rotors (2017)
Journal Article
Sturala, J., Etherington, M. K., Bismillah, A. N., Higginbotham, H. F., Trewby, W. J., Aguilar, J. A., Bromley, E. H., Avestro, A.-J., Monkman, A. P., & McGonigal, P. R. (2017). Excited-State Aromatic Interactions in the Aggregation-Induced Emission of Molecular Rotors. Journal of the American Chemical Society, 139(49), 17882-17889. https://doi.org/10.1021/jacs.7b08570

Small, apolar aromatic groups, such as phenyl rings, are commonly included in the structures of fluorophores in order to impart hindered intramolecular rotations, leading to desirable solid-state luminescence properties. However, they are not normall... Read More about Excited-State Aromatic Interactions in the Aggregation-Induced Emission of Molecular Rotors.
