摘要：

The synthesis of first and second generation carbosilane dendrimers with end-grafted triethylene glycol methyl ether units is reported. The reaction chemistry of Me2Si(CH2CHCH2SiMeCH2(CH2CH2O)(4)Me)(2) (4), Si(CH2CHCH2SiMeCH2(CH2 CH2O)(4)Me)(4) (5) and Si(CH2CH2CH2SiMe(CH2CH2)CH2SiMe2CH2(CH2CH2O)(4)Me)(2))(4) (7) towards alkali metal ions is described. ESI-TOF studies reveal that in 4 one, in 5 two and in 7 up to four metal ions can be trapped, which enables 4, 5 and 7 as possible ionophores for chemical sensors. (C) 2004 Elsevier B.V.
