Targeting large phosp(III)azane macrocyles [{P(mu-NR)}(2)(LL)](n) (n> or = 2)

The condensation reactions of the dimer ClP(micro-NR)](2) with organic diacids LL(H)(2)], possessing linear orientations of their organic groups, result in the formation of phospha(III)zane macrocyles of the type {P(mu-NR)}(2)(LL)](n) of various sizes. The series of macrocycles {P(mu-N(t)Bu)}(2){1,5-(NH)(2)C(10)H(6)}](3), {P(mu-NCy)}(2)(1,5-O(2)C(10)H(6))](n) n = 3; n = 4], {P(mu-N(t)Bu)}(2){1,4-(NH)(2)C(6)H(4)}](4), {P(mu-N(t)Bu)}(2)(1,4-O(2)C(6)H(4))], {P(mu-NCy)}(2)(1,4-O(2)C(6)H(4))](3) and {P(mu-N(t)Bu)}(2){(NH)C(6)H(4)OC(6)H(4)(NH)}](2) can be related to classical organic frameworks, like calixarenes.
