A method of forming a thermoresponsive polymer. The method begins by mixing in the presence of an organic solvent to form a monomer solution. An initiator is then added to the monomer solution to form a thermoresponsive polymer. In this method, R1 and R4 can be independently selected from the group consisting of H and alkyl groups; R2 and R3 can be independently selected from the group consisting of H, alkyl, olefinic, aromatic, heterocyclic, halogen, ammonium, nitroxides, nitrates, nitrite amides, amines, esters, ethers, carboxylic acids, acyl chlorides, alcohols, nitriles, phosphates, phosphonates, sulfates, sulfonates, sulfide, sulfite, thiol, and combinations thereof; Y can be selected from the group consisting of O, N and S; R5 and R6 can be independently selected from the group consisting of alkyl, olefinic, heterocyclic, halogens, ammonium, carboxylic, amines, esters, amides and combinations thereof; and X are methylene groups from about 0 to about 20 carbons.

A method of first dissolving a conjugated polymer in a fluid followed by adding an agent to the fluid and evaporating the fluid to produce a solid sample.

Method of purifying conjugated polymers

Methods, compositions and devices relate to photovoltaic cells having a photoactive layer and constituents synthesized and utilized for the photoactive layer. The photovoltaic cells incorporate photoactive materials produced from dyads formed into an initial layer and then thermally cleaved to provide the photoactive layer. Cleavage of the dyads, such as synthesized fullerene anthracen-2-ylmethyl 3-(thiophen-3-yl) acetate dyads, or polymers of the dyads into separate molecules providing donors and acceptors facilitates in obtaining the photovoltaic cells with desired arrangement and interspacing of the donors and the acceptors relative to one another.
