1. A method of making a composition comprising a sulfonated lignin having a first side arm comprising an amine group, and a second side arm comprising a hydroxyl group, the method comprising: contacting the sulfonated lignin with a first compound having an amine group and a second compound having a hydroxyl group under Mitsunobu conditions that allow for coupling of the first compound and the second compound to the sulfonated lignin. 2. The method of claim 1, wherein the contacting step comprises contacting the sulfonated lignin with a reduced amino acid. 3. The method of claim 1, wherein the contacting step comprises contacting the sulfonated lignin with a reduced lysine. 4. The method of claim 1, wherein the contacting step comprises contacting the sulfonated lignin with a poly (ethylene glycol). 5. The method of claim 1, wherein the contacting step comprises using reused or recycled reagents for the Mitsunobu conditions. 6. The method of claim 1, wherein the contacting step comprises contacting the reduced amino acid and sulfonated lignin such that the ratio of number of amine groups to number of sulfonate groups is about 1:2 to about 1:1000. 7. The method of claim 4, wherein the contacting step comprises contacting a poly(ethylene glycol) that has a chain length of about 2 to about 24.
