A robust compound is provided having the formula: ##STR1## wherein Y.sub.1, Y.sub.2, Y.sub.3 and Y.sub.4 are oxidation resistant groups which are the same or different and which form 5- or 6-membered rings with a metal, M, when bound to D. D is a metal complexing donor atom, O or N. Each X is a position for addition of a substituent and, when D is N, each position is (i) not occupied such that a double bond is formed between D and an atom adjacent to D, or (ii) is selected from the group consisting of hydrogen, alkyl, alkenyl, alkynyl, aryl, alkoxy, phenoxy, halogen, halogenated alkyl, halogenated aryl, halogenated alkenyl, halogenated alkynyl, perhaloalkyl, perhaloaryl, a substituted or unsubstituted cycloalkyl ring, a substituted or unsubstituted cycloalkenyl ring, a substituted or unsubstituted saturated heterocyclic ring, a substituted or unsubstituted unsaturated heterocyclic ring, and at least one X is hydrogen, and when D is O, the position is not occupied.
提供了一种具有以下公式的强韧化合物:##STR1##
其中,Y₁、Y₂、Y₃和Y₄是氧化抗性基团,它们相同或不同,并且当与D结合时与金属M形成5-或6元环。D是金属络合给体原子、O或N。每个X是添加取代基的位置,当D为N时,每个位置为(i)未占据,从而在D和邻近D的原子之间形成双键,或(ii)从氢、烷基、烯基、炔基、芳基、烷氧基、苯氧基、卤素、卤素化烷基、卤素化芳基、卤素化烯基、卤素化炔基、全氟烷基、全氟芳基、取代或未取代的环烷基环、取代或未取代的环烯基环、取代或未取代的饱和杂环环、取代或未取代的不饱和杂环环中选择至少一个X为氢,当D为O时,则该位置未被占据。
