The elongation method, originally proposed for theoretical synthesis of aperiodic polymers, has been reviewed. The reliability and efficiency of the elongation method have been proven by various systems. By means of orbital shift, the elongation method has been successfully applied to delocalized π-conjugated systems. During the elongation process, some strongly delocalized orbitals are assigned to active orbitals and joined with the interaction of the attacking monomer. The elongation method is also applied to determine the NLO properties of delocalized porphyrin wires.
