Investigation of charge-transfer complexes formation between photoluminescent graphene oxide and organic molecules

Charge-transfer complexes have formed between photoluminescent graphene oxide and organic electron-donating molecules. With the increase of electron-donating power of molecules, the colour of solutions containing complexes became darker; UV absorption was red-shifted to longer wavelength and a new charge-transfer complex emission was also enhanced.
