A molecular system, formed by the aza-macrocycle known as cyclen and functionalized dendrons, was synthesized in a convergent fashion. An aliphatic spacer between the two molecular units was incorporated to avoid the sterical hindrances. The N-acylation reactions to carry out the cyclen substitution, particularly those in solid state, resulted in very good yields since no further purifications were necessary. The obtained molecular system was ...
