"one functional group, thiophene ring-shaped compound of 1 sulfur atom/ 4 carbon atoms, is function-rich with interesting semiconducting/ fluorescence properties... fast/ easy fabrication, single-shot reaction: all nanobelts aligned with sulfur sides up on copper surface, but with sulfur sides down on gold surface... same synthesis strategy could also be used to create other varieties of carbon nanobelts... numerous requests for collaboration... building blocks for carbon nanotubes, polar materials, electronic/ optoelectronic devices"
