Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
125 words
A macropolycyclic compound corresponding to the formula: ##STR35## in which Z is a trivalent or tetravalent atom; R is nothing or represents hydrogen, the hydroxyl group, an amino group or a hydrocarbon radical; and the divalent radicals A, B and C independently of one another are selected from the group consisting of hydrocarbon chains, which hydrocarbon chains with one or more heteroatoms and interrupted by heteromacrocycle, wherein at least one of the radicals A, B and C includes or consists essentially of a radical selected from the group consisting of ##STR36## provided that when Z is N and A is radical 5 or 6, then B and C may not simultaneously be --(CH 2 ) 2 --O--(CH 2 ) 2 --O--(CH 2 ) 2 --.
Claim 2
Dependent Claim
125 words
A macropolycyclic compound corresponding to the formula: ##STR35## in which Z is a trivalent or tetravalent atom; R is nothing or represents hydrogen, the hydroxyl group, an amino group or a hydrocarbon radical; and the divalent radicals A, B and C independently of one another are selected from the group consisting of hydrocarbon chains, which hydrocarbon chains with one or more heteroatoms and interrupted by heteromacrocycle, wherein at least one of the radicals A, B and C includes or consists essentially of a radical selected from the group consisting of ##STR36## provided that when Z is N and A is radical 5 or 6, then B and C may not simultaneously be --(CH 2 ) 2 --O--(CH 2 ) 2 --O--(CH 2 ) 2 --.
