Welcome to Molecular Materials Lab

We are synthetic chemists who like to play with synthesis tools and create exciting functional molecular materials.

We are interested in designing new molecular materials for opto-electronic applications. Our primary focus is on the synthesis of ideal fluorescent systems capable of exhibiting exciting optical properties, specially, circularly polarized luminescence (CPL). We aim to prepare multi-chromophoric molecules with inherent chirality and study emission properties of individual molecule and their self-assembled structures.

Excited state energy transfer and energy funneling play crucial roles in light harvesting systems. Artificial photosynthesis or phenomena of light harvesting in general, rely on the photophysical properties of chromophore as well as upon their molecular arrangement in the bulk. Utilizing LEGO-chemistry, we aim to design highly efficient light harvesting systems. Triplet-triplet annihilation based photon up-conversion (TTA-UC) is one such closely related property. TTA-UC has been shown to be capable of upconverting the mild intensity light covering solar irradiance levels. We aim to widen the scope of up-conversion process by designing new donor/acceptors.

We are also interested in design and synthesis of rotaxane and catenane based materials with particular interest in systems allowing external stimuli based action or mechanical activities.
