The LUMO electron density geometry distribution of N-TPA1 is located on the cyanoacrylic group which favour electron injection,but for N-TPA2 it is mainly concentrated on the rhodanine framework,and resulting in the position of LUMO isolated from the -COOH anchoring group due to the presence of the -CH_2- group.

由于罗丹宁乙酸基团的羰基与五元环构架间隔一个亚甲基，使得LUMO电子分布距离吸附基团远，阻碍电子经由羰基注入TiO_2导带，这是N-TPA2的敏化电池效率比N-TPA1低的原因之一。
