Heteroatom‐doped graphene is emerging as an outstanding material for tailoring the properties of graphene by chemical functionalization. With the use of classical click chemistry, N‐doped graphene has been functionalized to carry well‐known photosensitizer electron donors, viz., zinc porphyrin and zinc phthalocyanine. Efficient singlet quenching of photosensitizers was witnessed in these hybrids, and the ultrafast pump–probe technique provided evidence of excited‐state charge separation in these hybrids, thus making them useful candidates for applications in harvesting light energy.
