Three dimensional conjugated three- and four-armed molecules with core-D–π–A and core-A–π–D topologies were designed and studied by DFT, revealing that molecules with the core-A–π–D topology and N or C cores would result low reorganization energies and broad absorption bands for organic solar cells.
