Dendrimer molecules, glass transition

This has been done by using poiymeric systems with heavy atoms (metals) in the backbone [163] thus increasing the ISC rate [169], or by multilayered structures of small molecules and metal complexes [142], The multiple functionalities needed for the ISC can be inserted in dendrimers having, in comparison to linear systems with the same molecular weight, a lower intrinsic viscosity and abetter solubility [170], possibly associated to a control of the glass transition temperature and chemical reactivity [170],...
