1. A quaternary phosphonium salt represented by Formula 1: wherein: R1, R2, R3, and R4 are each independently a substituted or unsubstituted C1-C30 hydrocarbon group or a substituted or unsubstituted C1-C30 hydrocarbon group including at least one heteroatom; X is a substituted or unsubstituted C1-C30 hydrocarbon group or a substituted or unsubstituted C1-C30 hydrocarbon group including at least one heteroatom; Y is a substituted or unsubstituted C1-C30 hydrocarbon group or Si substituted with one to three substituted or unsubstituted C1-C30 hydrocarbon groups; n and m are each independently an integer of 1 to 6, provided that when Y is Si, a sum of m and a number of substituents on the Si is a maximum of 4; and l is a number greater than 0 and up to 6.
