In this report, a method for deconvoluting the multi-band spectra of charge-transfer complex is presented and a relation between double-bands is proposed. 49 such spectra in which double-bands appear are calculated. It has been found that the deviation between the calculated and the measured values is less than 3%. The scheme can be extended to deconvolute the CT peaks are used to evaluate the electron affinities of these acceptors. But, the scheme can be used to the π-π charge-transfer complexes. 相似文献

前文提出了不同溶剂中电荷转移复合物平衡常数(K_(CT))与溶剂极性的关系。但是实验限于小分子体系,未曾涉及高分子化合物。高分子电荷转移复合物的研究,由于它的实际应用而得到迅速发展,并且深入到生物高分子领域。本文的目的是研究溶剂极性对高分子电荷转移复合物(CTC)平衡的影响。以聚N-乙烯咔唑为给体,恰好前文中的乙基咔唑是其模型化合物,两个研究结果可以进行有意义的比较。实验部分聚乙烯咔唑(PVK)由通常的自由基聚合制备,以气相渗透仪(VPO)测定分子量为7200±3%.受体硝基芴酮类,各参数见文献[2]。所用溶剂与前文同。用VPO在25℃测量平衡常数,数据处理方法见文献[3]。 相似文献

The method to evaluate the reversible lithium insertion capacity (Qre) has been studied using poly (p-phenylence) (PPP) heat-treated at 550 1000 ℃ in inert gas atomsphere by H/C atomic ratio and FTIR measures. The H/C atomic ratio and Qre decreased with increasing heat-treament temperature. The absorption ratio of 1020cm-1 band to the 1440cm-1 band (Ra) is directly related to the Qre of carbon samples. The samples with R. >1-1 and without 807cm-1 peak tend to have high Qre (>372 mA.h-g-1). The reversible capacity for Li+ ion insertion decrease as Ra decreases. 相似文献

]本文从溶质分子间的电荷转移相互作用,讨论了溶质浓度对色谱过程的影响。由于溶质分子间的相互作用,在一定的浓度范围内改变了固定相的表面吸附状态,改变色谱分离效果,两相邻色谱峰的分辨率随溶质浓度而变化。文中以液体色谱为例,着重从理论上进行阐述,力图得出一些清新的概念。这些概念同时也适合于气相色谱,只不过在方程式的表达上略有不同。 相似文献

The charge-transfer complexes of poly(N-vinylcarbazole) (Mn=7200) and nitro- fluorenones were studied with VPO in different solvents. The relationship between equilibrium constant and solvent dipole moment was examined. The results obtained from polymer and model compound were compared, and the reason of their difference was explained. The relationship between the equilibrium constant and the molecular weight was given: InK_(CT)=InK_(CT)~∞+2M_0/M(InK°-InK~∞) 相似文献
