Single oxygen generation sensitized by spiro(dipyridinogermole)(dithienogermole)s
Three spiro(dipyridinogermole)(dithienogermole) derivatives ( 1-3 ), including newly prepared spiro(dipyridinogermole)[di(2-pyridyl)dithienogermole] ( 3 ), were examined as photosensitizers for singlet oxygen ( 1 O 2 ) generation in dichloromethane-methanol. Irradiation of their air-saturated soluti...

| description | Three spiro(dipyridinogermole)(dithienogermole) derivatives (
1-3
), including newly prepared spiro(dipyridinogermole)[di(2-pyridyl)dithienogermole] (
3
), were examined as photosensitizers for singlet oxygen (
1
O
2
) generation in dichloromethane-methanol. Irradiation of their air-saturated solutions led to the generation of
1
O
2
, which was readily trapped by well-known scavengers, dihydronaphthoquinone (DHN) and diphenylisobenzofuran (DPBF). Spiro(dipyridinogermole)[bis(
n
-hexylbithiophenyl)dithienogermole] (
2
) showed the best performance with a first-order rate constant that was higher than that of tetraphenylporphyrin (TPP), an efficient photosensitizer for
1
O
2
generation. This is ascribable to the efficient intersystem crossing characteristic of the dipyridinogermole unit. The quantum yield of
1
O
2
generation was
Δ
= 0.72 for
2
, relative to that for rose bengal (RB) in methanol as reference (
Δ
= 0.8).
