Role of spin density and interchromophoric coupling in singlet fission
Singlet exciton fission (SEF) is the transformation of a photoexcited singlet exciton into two triplets localized on two chromophores coupled together. This process therefore produces two triplet excitons at the expense ...
Quantum Phases and Magnetization Plateaus of Skewed Spin Ladders
This thesis deals with theoretical studies of skewed spin ladders which are two legged ladder with periodic slanted rung bonds and can be viewed as periodic fused rings with two different number of vertices. The spin at ...
Supramolecular Self-assembly of Diketopyrrolopyrrole with Emergent Photophysics and Unprecedented Photoconductivity
Structural fluctuation in organic molecular semiconductors often plays a key role in fragmenting the conducting pathways even in their condensed phases due to the large fraction of free volumes, acting as trap sites for ...
