A method of synthesizing a biopolymer material, the method comprising:
- dissolving a biopolymer in a non-protic polar solvent to form a dissolved biopolymer,
- contacting the dissolved biopolymer with a compound of the formula HO—(CX2)n—CX3, wherein each X is independently selected from F, Br, I, Cl, or combinations thereof;
- and wherein n is an integer from 2 to 18.

A method of catalyzing a reaction with a multi-phase biopolymer catalyst support system, the method comprising:
- covalently coupling an additive with a functionalized biopolymer;
- combining the functionalized biopolymer covalently coupled to the additive with a halogenated solvent to create a halogenated solvent phase;
- adding an organic solvent to form an organic solvent phase, wherein the organic solvent phase and halogenated solvent phase are immiscible at ambient temperature and pressure;
- providing a plurality of reaction substrates for the reaction, wherein the reaction substrates are contained in the organic phase;
- heating the system for a duration of time for the reaction to proceed to a desired yield of reaction product;
- separating the organic solvent phase from the halogenated solvent phase to obtain the reaction product at the desired yield.
