摘要

The photophysical properties of the compound [(ThiaSO(2))(Mn-II)(2)(DMF)(4)(H2O)(2)] (2), ThiaSO(2) = p-tert-butylsulfonylcalix[4]arene, are presented and compared to the ones of [(ThiaSO(2))(2)(Mn-II)(4)F]K (1). The orange luminescence of 2 is attributed, as for 1, to the Mn-II centred T-4(1)->(6)A(1) transition and shows, for this type of complex, the weak influence of the Mn2+ coordination and ThiaSO(2) conformation on this luminescence, the temperature and pressure dependence and quenching by molecular dioxygen of which are reported for 2. The latter is attributed to energy transfer from the T-4(1) state exciting dioxygen to its (1)sigma(+)(g) state and is responsible for the photosynthesis of the [(ThiaSO(2))(Mn-III)(DMF)(2)]Na (3) complex in DMF solution from 1 or 2. This reaction was studied by UV/Visible and EPR spectroscopy. The molecular structure and EPR spectroscopy of 3 are also presented.
