ÔÎÄժ¼ÈçÏ£º The designed small molecules (SMs) provide comprehensively different molecular packing/ordering and orientation via the additional alkyl substituent group. The control compound (SM1, R = H) exhibited a predominant edge-on orientation, whereas the newly synthesized SM2 (R = hexyl) formed a well-ordered preferential face-on orientation. This means the backbone orientation can be altered from the vertical to horizontal direction through alkyl side-chain substitutions, which can significantly influence the charge transfer/transport and recombination and in turn the device performance in OPVs and PvSCs.
