Crystal Engineering and Substituent Effect of Hindered Phenols for SHG Materials

Article abstract of DOI:10.1246/cl.1992.1743

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.
