Amplified two-photon absorption in trans-A2B2-porphyrins bearing nitrophenylethynyl substituents.
We show that peripheral nitro groups enhance the maximum two-photon absorption cross-section of trans-A(2)B(2)-porphyrins bearing two phenylethynyl substituents by more than one order of magnitude. Maximum values as high as 1000 GM result from realization of suitable conditions for effective resonan...
