The transfer behavior of pyrazolone derivatives, such as antipyrine, aminopyrine, 4-aminoantipyrine and analgin, across the W/NB interface was investigated. The three medicines studied can form complex with a proton and the complex formed can transfer reversely across the W/NB interface and the transfer process was controlled by diffusion. The transfer of protonated analgin was not observed within potential window because of its high transfer potential.

Because the rate of ET and HT reactions is determined by the coupling term J, and in long range ET and HT systems the degeneracy of the π orbitals of donor and acceptor is lifted through mixing with the bridge orbitals of appropriate symmetry by an amount △E. Because the △E splittings are proportional to electronic coupling, so we can use the static quantity △E to exploring the dynamic quantity J, and to make a detailed study on the microscopic influence of coupling mechanism in ET and HT process.

由于电子转移和空穴转移反应速率的大小决定于反应的耦合因子，在长程电子转移和空穴转移体系中，给体和受体的简并π轨道由于与饱和桥之间的TB作用而产生一定的分裂能，此分裂能又与耦合因子的数值成正比，因此，我们可以用静态的分裂能数值间接地表征动态的耦合因子，从而详细研究电子转移和空穴转移过程中耦合机理的微观影响因素。
