The mechanism of electron transfer in α-aminoisobutyric (Aib) homoligomers is defined by the extent of secondary structure, rather than just chain length. Helical structures (Aib units â¥3) undergo an electron hopping mechanism, while shorter disordered sequences (Aib units <3) undergo an electron superexchange mechanism.

异丁酸(Aib)均聚物中的电子传递机制是由二级结构的程度而不仅仅是链的长度决定的。螺旋结构(Aib单位≥3)采用电子跳跃机制,而较短的无序序列(Aib单位<3)则采用电子超交换机制。
