Handedness inversion of chiral mesoporous silica: A diffuse-reflectance circular dichroism study

论文摘要

Chiral mesoporous silica ribbons and rods with inversed handedness have been synthesized with the same enantio pure N-acylaminoacidat temperatures of 0℃and 20℃ respectively. With involving Cu2+and meso-tetra（4-sulfonatophenyl）porphyrin（TPPS） as probes, ribbons and rods revealed opposite signals in diffuse-reflectance circular dichroism（DRCD） spectra, indicating the existence of inversed supramolecular chiral imprintings through helical stacking of amphiphiles. The structural evolution was systematically studied by the freeze-dried products sampled at different time after the addition of silica precursors. The H-bonding-depended molecular orientation probably controls the chiral sense upon forming chiral molecular stacking, which would be the origin of such handedness inversion phenomenon
