Mppa which Qy at 668 nm was used as staring material for the synthesis of a series of new Mppa derivations, the modification of function groups of MPPa along N~(21)-N~(23) axis and effect on their NMR and visible spectra were discussed.

• 选择最大可见光吸收Qy为668nm的MPPa为起始原料,对N~(21)-N~(23)的轴向对其化学官能团进行化学修饰,在3-位引进带有不同链长的醛基和酮基,合成了一系列新的焦脱镁叶绿酸-a甲酯衍生物,并且对二氢卟吩周边取代基团的变化对核磁共振光谱及可见光吸收光谱的影响进行讨论。
