Abstract:
1. A supramolecular material comprising: (a) a polymer comprising at least two 4H-units; and (b) a biologically active compound covalently bonded to one to ten 4H-units that are not the 4H-units of (a); wherein the supramolecular material comprises 50.00-99.99 percent by weight of the polymer and 0.01-50.00 percent by weight of the biologically active compound, based on the total weight of the supramolecular material; and wherein the 4H-units of (a) and (b) have the general formula (3) or formula (4) and tautomers thereof: wherein X is nitrogen atom or a carbon atom bearing a substituent R (i) hydrogen; (ii) C (iii) C (iv) C (v) C (vi) polyester groups having the formula (5) wherein R (vii) C wherein R (viii) polyether groups having the formula (7) wherein R wherein the least two 4H-units of (a) are bonded to the backbone of the polymer via R wherein the 4H-units of (b) are bonded to the biologically active compound via R
