2,6-Di-tert-butylphenol moiety was found to be effective to control molecular packing in crystals for SHG materials. Many derivatives having compact acceptor group at 4-position of hindered phenols showed SHG responses depending on the electron withdrawing effect of an acceptor. The X-ray structural analyses revealed that molecular packing was controlled both by the steric requirements and the intermolecular hydrogen bonding.
研究发现,含有2,6-二叔丁基苯酚部分的化合物能够有效控制SHG材料的晶体分子堆积。许多在受阻酚4位具有紧凑受体基团的衍生物,其SHG响应取决于受体的吸电子效应。X射线结构分析揭示,分子堆积既受到空间位阻要求的控制,也受到分子间氢键的影响。
