Manipulation of n → π* electronic transitionsviaimplanting thiophene rings into two-dimensional carbon nitride nanosheets for efficient photocatalytic water purification

Thiophene ring implanted two-dimensional carbon nitride nanosheets (2D Th ing -CNNS) with dramatically double elevated n → π* electronic transitions were synthesized. 2D Th ing -CNNS exhibited efficient photocatalytic bisphenol-A degradation.
