M. Albrecht et al., SULFUR-DIOXIDE GAS-DETECTION BY REVERSIBLE ETA(1)-SO2-PT BOND FORMATION AS A NOVEL APPLICATION FOR PERIPHERY FUNCTIONALIZED METALLO-DENDRIMERS, Chemical communications, (9), 1998, pp. 1003-1004
Multimetallics such as dendrimer 3 which are functionalised at their p
eriphery with platinum(II) metal centres reversibly absorb SO2 to yiel
d macromolecules with significantly enhanced solubility characteristic
s and drastic colour changes; properties which make these compounds hi
ghly active sensors for milligram quantities of toxic SO2 gas.
