and Q is selected from — — -S- or -O- , which is bound to the W dendron
scaffold through the Y linker, so that the X resulting moiety is:
wherein R 2 , n and Q have the above defined meanings.
Within formula (Ia), Y is a bifunctional linker, which is capable of binding the X
moiety to one end and the dendron W scaffold to the other end; in particular, it
can be a single bond, so that the dendron scaffold W is directly linked to each
