同系列电子给体与同系列电受体电荷转移络合作用的研究

用电子吸收光谱法, 研究了五个电子受体系列和三个电子给体系列以及非同系列的给、受体共48个化合物间的弱电荷转移络合作用。发现所研究的同系列给体与同一受体作用; 或同系列受体与同一给体作用; 或同系列给体与同系列受体作用, 一般存在着明显的CT络合与表观不络合的现象。通常情况下, 同系序数大的化合物呈现表观不络合;有时, 同系序数大和小的化合物, 即同系物的两头均呈现表观不络合现象, 对此种现象用给、受体间前线分子轨道能级关系进行了讨论。

Investigation of CT-Complexation among homologous donors and homologous acceptors

The weak charge-transfer complexations among 48 compounds, including 5 acceptor and 3 donor homologous series have been investigated by electronic spectroscopy. Both complexation and apparent noncomplexation exist in cases of interaction of homologous donors with same acceptor, homologous acceptor with same donor, or homologous donors with homologous acceptors. Generally, the higher homologs exhibit apparent noncomplexation; in some cases, both the higher and the lower homologs exhibit apparent noncomplexation. This phenomenon was discussed in terms of of FMO energies.
