What is claimed is: 1. A base generator having the structure of formula (1): wherein R 1 is H, linear or branched C 1 -C 6 alkyl, linear or branched C 1 -C 6 haloalkyl, linear or branched C 1 -C 6 alkyl substituted with one or more C 6 -C 14 aryl, and R 2 is wherein R 6 is branched C 1 -C 6 alkyl, linear or branched C 1 -C 6 haloalkyl, linear or branched C 1 -C 8 alkoxy unsubstituted or substituted with one or more C 6 -C 14 aryl, or —NR 10 R 11 , and R 7 , R 8 , R 10 and R 11 are the same or different, and are each independently H, linear or branched C 1 -C 14 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl, and R 9 is H, linear or branched C 1 -C 14 alkyl substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl; R 3 , R 4 and R 5 are the same or different, and are each independently H, linear or branched C 1 -C 6 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, linear or branched C 1 -C 6 hydroxyalkyl, linear or branched C 1 -C 6 cyanoalkyl, or C 6 -C 14 aryl; and Y {circle around (−)} is an anionic group. 2. The base generator according to claim 1 , wherein R 1 is linear or branched C 1 -C 6 alkyl, and R 2 is wherein R 6 is branched C 1 -C 6 alkyl, linear or branched C 1 -C 6 haloalkyl, linear or branched C 1 -C 8 alkoxy unsubstituted or substituted with one or more C 6 -C 14 aryl, or —NR 10 R 11 ; and R 7 , R 8 , R 10 and R 11 are the same or different and are each independently H, linear or branched C 1 -C 14 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl; and R 9 is H, linear or branched C 1 -C 14 alkyl substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl. 3. The base generator according to claim 1 , wherein R 1 is methyl, ethyl, propyl, butyl or selected from a group consisting of: and R 2 is 4. The base generator according to claim 1 , wherein R 1 is methyl, ethyl or selected from a group consisting of: 5. The base generator according to claim 1 , wherein R 3 , R 4 and R 5 are the same or different and are each independently H, methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl, pentyl, hexyl, hydroxymethyl, hydroxyethyl, hydroxypropyl, hydroxybutyl, hydroxypentyl, hydroxyhexyl, cyanomethyl, cyanoethyl, cyanopropyl, cyanobutyl, cyanopentyl, cyanohexyl, phenyl, benzyl or diphenylmethyl. 6. The base generator according to claim 1 , wherein R 3 , R 4 and R 5 are the same or different and are each independently H, methyl, ethyl, n-propyl or isopropyl. 7. The base generator according to claim 1 , wherein the anionic group is selected from a group consisting of halide ion, sulfate, nitrate, phosphate, sulfonate, carbonate, tetrafluoborate, borate, chlorate, iodate, hexafluorophosphate, perchlorate, trifluoromethanesulfonate, trifluoroacetate, acetate, tert-butylcarbonate, (CF 3 SO 2 ) 2 N − and tert-butyloxy. 8. The base generator according to claim 1 , wherein the anionic group is a halide ion or tetrafluoroborate. 9. The base generator according to claim 1 , which is an optical base generator or a thermal base generator. 10. A base generator having the structure of formula (1): wherein R 1 is H, or linear or branched C 1 -C 6 haloalkyl, and R 2 is linear or branched C 1 -C 6 alkyl substituted with one or more C 6 -C 14 aryl, wherein R 7 and R 8 are the same or different, and are each independently H, linear or branched C 1 -C 14 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl, and R 9 is H, linear or branched C 1 -C 14 alkyl substituted with one or more C 6 -C 14 aryl, or C 6 -C 14 aryl; R 3 , R 4 and R 5 are the same or different, and are each independently H, linear or branched C 1 -C 6 alkyl unsubstituted or substituted with one or more C 6 -C 14 aryl, linear or branched C 1 -C 6 hydroxyalkyl, linear or branched C 1 -C 6 cyanoalkyl, or C 6 -C 14 aryl; and Y {circle around (−)} is an anionic group. 11. The base generator according to claim 1 , wherein R 1 is linear or branched C 1 -C 6 alkyl. 12. The base generator according to claim 10 , wherein R 1 is linear or branched C 1 -C 6 haloalkyl. 13. The base generator according to claim 1 , wherein R 1 is linear or branched C 1 -C 6 alkyl substituted with one or more C 6 -C 14 aryl,
