Executive Summary : | Nitrogen-rich aromatic compounds, such as triazine-based materials, have been extensively studied for their optical and electronic properties. However, their higher congener s-heptazine (tri-s-triazine) has remained relatively unexplored. s-Heptazine, the structural motif of graphitic carbon nitride, has a C/N ratio = 0.85 and is believed to be responsible for its catalytic activity. Molecular and monomeric s-heptazines and their materials have been the subject of intense research worldwide. Conventional synthesis of s-heptazine core involves calcination at temperatures above 340°C, but only a few precursors are available. This presents a challenge in finding new precursors for s-heptazine synthesis. The proposal aims to identify precursors for s-heptazine core synthesis and design monomeric materials that are soluble in common solvents. This will enable the complete characterization of these materials and be used to synthesize various framework materials, such as MOF and COF. Capture and utilization of CO₂ is a step towards reducing atmospheric CO₂ levels and depleting fossil fuel reserves. Research on sustainable CO₂ sequestration is growing due to its environmental benefits and energy demands. Nitrogen-rich materials have gained interest due to their potential affinity for CO₂. S-Heptazine-containing molecules and materials are an emerging area of research with significant potential for exploration. Highly stable s-heptazine cores are expected to enhance the stability of the resulting materials, and s-Heptazine-containing catalysts for CO₂ utilization are largely unexplored. |
