Sc3N@I h -C80 based donor-acceptor conjugate: role of thiophene spacer in promoting ultrafast excited state charge separation.

Light induced charge separation in a newly synthesized triphenylamine-thiophene-Sc3N@I h -C80 donor-acceptor conjugate and its C60 analog, triphenylamine-thiophene-C60 conjugate is reported, and the significance of the thiophene spacer in promoting electron transfer events is unraveled.
