Design strategies which allow to independently control the strength, position, fluorescence quantum yield and intersystem crossing rates for two-photon absorbing organic molecules have been developed. Specifically, the position and strength of the band of the two-photon absorption peak in conjugated molecules can be controlled by varying the conjugation length and also by appropriate substitution of the molecule with electron donating and electron withdrawing groups. The fluorescence quantum yield can also be controlled by an appropriate choice of the p-electronic system of the molecule.
