Room temperature optical control of spin states in organic diradicals
Rituparno Chowdhury, Alistair Inglis, Lucy E. Walker +13
We report a family of luminescent alternant diradicals which, at room temperature, support a ground-state spin-triplet, near-unity photoluminescence quantum yields, and optical spi…

Circularly polarised electroluminescence from chiral excitons in vacuum-sublimed supramolecular semiconductor thin films
Rituparno Chowdhury, Marco D. Preuss, Hwan-Hee Cho +21
Materials with chiral electronic structures are of great interest. We report a triazatruxene, TAT, molecular semiconductor with chiral alkyl side chains that crystallises from solu…

Optical read and write of spin states in organic diradicals
Rituparno Chowdhury, Petri Murto, Naitik A. Panjwani +17
Optical control and read-out of the ground state spin structure has been demonstrated for defect states in crystalline semiconductors, including the diamond NV- center, and these a…
