摘要：

The reaction of Finland trityl with tertiary aliphatic alcohols containing a terminal tertiary amino group, followed by quaternization of the amino groups, afforded new highly polar tri- and hexacationic derivatives. The obtained compounds are characterized by a sharp singlet signal in the EPR spectrum and are soluble in water over a wide pH range.
