Designing intramolecular singlet-fission materials using indeno[1,2-b]fluorene dimers: A DMRG and TDDFT study
Sumit Naskar, Mousumi Das
Low-lying excited states for indeno[1,2-b]fluorene homo dimers with or without benzene spacers are calculated using the Density Matrix Renormalization group (DMRG) approach within…
Computational investigation on non-linear optical properties of hexaphyrin and core modified hexaphyrins
Sumit Naskar, Mousumi Das
Expanded porphyrin-based (Hexaphyrins) sensitizers are promising due to their excellent light harvesting feature in dye-sensitized solar cell (DSSC). We calculated the low-lying ex…
Dissociative electron attachment to sulfur dioxide : A theoretical approach
Irina Jana, Sumit Naskar, Mousumi Das +1
In this article, density functional theory (DFT) and natural bond orbital (NBO) calculations are performed to understand experimental observations of dissociative electron attachme…
Role of Electron--Electron Interactions on Spin Effects in Electron--Hole Recombination in Organic Light Emitting Diodes
Mousumi Das, S. Mazumdar, S. Ramasesha
We extend our theory of electron--hole recombination in organic light emitting diodes to investigate the possibility that high energy singlet and triplet excited states with large…
Comment on "Triplet-to-Singlet Exciton Formation in poly(p-phenylene-vinylene) Light-Emitting Diodes"
S. Mazumdar, Mousumi Das, S. Ramasesha
The low-lying singlet and triplet spectrum in conjugated polymers clearly show that the mechanism proposed by Lin et al. to explain their electric field dependence of singlet to tr…
