Covalent organic frameworks (COFs) are covalently linked crystalline porous organic polymers formed by a bottom-up synthesis from symmetric molecular building blocks. Desirable chemical functionalization, tunable pore size, large surface area, high crystallinity, and lightweight make COFs a promising material for gas storage and separation, catalysis, optoelectronics, sensing, drug delivery, energy harvest and storage.

We aim to create porous semiconducting and conducting COFs for various applications.

Supramolecular semiconductors (OSCs) are ordered assembly of π-conjugated small molecules or oligomers and these are promising functional materials for flexible and printable optoelectronics, such as solar cells, field effect transistors (FET), and light emitting diodes (LED). The optical and electronic properties of OSCs can be tuned through bottom-up synthesis and controlled molecular aggregation.

We look for supramolecular semiconductors with tunable bandgap, polarity (p/n-type) and high charge carrier mobility for flexible electronics.

Hydrogen (H2) is the renewable and environmental friendly fuel for sustainable society and economy. Green production of hydrogen from the naturally abundant sources like water using inexhaustible sunlight is highly challenging.

We aim to develop porous semiconductors with enhanced light harvesting properties, tunable functionalities and bandgap for efficient and green production of H2 from water and other alternatives using solar energy. Photocatalytic water splitting will be our ultimate goal.
