Occurrence of excited state charge separation in a N-doped graphene-perylenediimide hybrid formed via 'click' chemistry.

ABSTRACT: Hetero-atom doped graphene is a two-dimensional material with a band gap, needed to build optoelectronic devices. However, research progress in this area has been sluggish due to synthetic challenges to build energy harvesting materials, especially donor-acceptor type hybrids. In the present study, using click chemistry, we have successfully synthesized a donor-acceptor hybrid comprised of N-doped graphene and perylenediimide (PDI), a well-known electron-accepting photosensitizer. The TGA and XPS results revealed the attachment of the PDI moiety in the hybrid. Ground and excited state interactions were monitored by a variety of spectral and electrochemical techniques. Finally, the ability of the present donor-acceptor hybrid to undergo photoinduced charge separation from singlet exc
