The work is divided into four parts : (1) MRI contrast agents are designed to enhance T₁ relaxivity by coupling them to dendrimers, the precise structure of which can be controlled through synthesis. Cyclen is used as a starting scaffold for the synthesis of bifunctional Gd-DOTA and Gd- DOTMA analogues. One unique side chain on the macrocycle contains an azide moiety that can be clicked to an alkyne- containing core, making a first-generation dendrimer with the potential to improve MRI efficiency. (2) PET tracers are designed to specifically coordinate ⁶⁴Cu, a positron source, while containing clickable side arms. A functionalized cross-bridge tetraazamacrocycle...
