Abstract

One of the oldest organic moiety reported in the 19th century, Heptazines (tri-s-triazines) are one of the forefront moiety in the form of polymeric graphitic carbon nitrides (especially known as g-C3N4 or g-CN) today. It attained profound importance after it’s application as first organic semiconductor for water splitting to generate hydrogen in the visible light. From that point there is no looking back, where it is being applied in numerous energy and environment related applications. Our group working extensively on synergistic photoredox catalysis to produce solar fuels and fine chemicals in more sustainable way. Even though one of the oldest organic molecule known, s-heptazine moiety was seldom explored until eventual breakthrough around the year 2002. Heptazine has driven scientists to develop different functional materials which is least explored till now. Especially our group is involved in various material-designs on synthesizing molecular compounds and heptazine based micro/mesoporous organic polymers (HMPs) as liquid crystals, gas storage, and for various photoredox catalytic transformations.
