The effect of the functional ionic group of 4,4′-bipyridinium salt derivatives (4,4′-BPs) as the electron carrier on the visible-light driven conversion of CO₂ to formic acid with the system consisting of water-soluble zinc tetraphenylporphyrin tetrasulfonate (ZnTPPS) and formate dehydrogenase (FDH) in the presence of triethanolamine (TEOA) as an electron donor was investigated. 1,1′-Diaminoethyl- (DAV), 1-aminoethyl-1′-methyl- (AMV), 1-carboxymethyl-1′-methyl- (CMV) and 1,1′-dicarboxymethyl-4,4′-bipyridinium salt (DCV) were prepared as the 4,4′-BPs with the functional ionic group. Irradiation of a CO₂ saturated buffer solution containing TEOA, ZnTPPS, 4,4′-BP and FDH with visible light irradiation resulted in the production of formic acid. By using 4,4′-BPs with the cationic aminoethyl-group, DAV or AMV as an electron carrier, the effective visible-light driven formic acid production based on the CO₂ reduction was observed compared to the 4,4′-BPs with the anionic carboxymethyl-group, CMV or DCV. The formic acid production rate with DAV was approximately 3.2 times higher than that of the system with DCV.

水溶性卟啉锌和甲酸脱氢酶组成的体系，紫精衍生物的功能性离子基团对可见光驱动的CO ₂还原成甲酸的影响†

4,4'-联吡啶鎓盐衍生物（4,4'-BPs）的功能性离子基团对水溶性锌构成的体系在可见光驱动下将CO ₂转化为甲酸的影响在三乙醇胺（TEOA）作为电子供体的情况下，研究了四苯基卟啉四磺酸盐（ZnTPPS）和甲酸脱氢酶（FDH）。1,1'-二氨基乙基-（DAV），1-氨基乙基-1'-甲基-（AMV），1-羧甲基-1'-甲基-（CMV）和1,1'-二羧甲基-4,4'-联吡啶鎓将盐（DCV）制备为具有功能性离子基团的4,4'-BP。辐照CO ₂含有TEOA，ZnTPPS，4,4'-BP和FDH的饱和缓冲溶液并在可见光照射下产生了甲酸。通过使用带有阳离子氨基乙基，DAV或AMV的4,4'-BPs作为电子载体，与具有1,4-氨基苯甲酸的4,4'-BPs相比，观察到了有效的可见光驱动的基于CO ₂还原的甲酸生产。阴离子羧甲基，CMV或DCV。DAV的甲酸产率比DCV的系统高约3.2倍。
