Metal complexed acetylenic compounds useful as environmental indicating materials |
摘要 |
Acetylenic complexes are disclosed that are useful as environmental indicating materials whereby exposure thereof to environmental stimuli induces a color change. These complexes contain at least one effective complexing metal and at least one acetylenic compound of the general formula: [R-(C"C)a-(CH2)b-(C"C)c]2.dHX Wherein a is 1 or 2, b is about 0-5; c is 0 or 1; with the proviso that when a is 1, b and c are 0, when a is 2, b is about 0-5 and c is 0 or 1; and R is -(CH2)n-NHC(O)NHR'; wherein n is an integer of about 1 to 10; and R' is selected from the group consisting of: (a) hydrogen; (b) cycloalkyl; (c) alkenyl; (d) cycloalkenyl; (e) alkyl; (f) phenyl; (g) alkoxy; (h) alkoxy alkyl; and (i) alkoxycarbonylalkyl.
