摘要：

The photochemistry of benzophenone and xanthone within calix[6]arene solid matrices is dominated by their triplet excited states. Triplet decays within hexat-butyl-37,38,39,40,41,42-hexaethoxycalix[6]arene host matrices are remarkably simple; while benzophenone triplet decays can be adequately described by a two-exponential function, decays for xanthone (a less flexible ketone than benzophenone) are very well reproduced by a single discrete lifetime model.
