当一个有机分子如电子给予体吡啶吸附在表面上时，阳离子由于电子转移而还原。

When an organic molecule like electron donating pyridine adsorbs on the surface, cations get reduced due to charge transfer.

我们根据实验结果并借鉴前人的经验，指出低聚物阳离子自由基向单体的链转移是诠释这一切问题的关键。

We find that the chain transfer reaction between oligomeric radical cations and monomers is the key to elucidate these questions.

主要原因可能是形成配合物后电子由配体流向配位的中心阳离子，增加了电子的转移能力。

Thus could be resulted from the complexation by which increases the electron density of the metal ion through partial sharing of its positive charge with donor groups.
