The ground state and lower--lying excited states of polydiacetylene chainsare investigted using a tight--binding Hamiltonian which includes electron-phonon interaction but does not explicitly include electron--electron repulsion.We have given a detail discussion about the electronic excited state at 2evand used this result to interpret the reflection spectrum of TS polymer atroom temperature successfully.

聚乙二炔链中的电子激发态是一个非常复杂的问题,由于它是少数几个难得的、具有良好结晶的有机聚合物之一,对于检验分子量子理论是一个理想的有机聚合物体系。它也具有特殊的光学和输运性质,故引起了人们极大的兴趣。假定聚乙二炔链中的π电子和σ电子可分开处理,对于σ电子,利用半经典的弹性理论,对于π电子,从紧束缚哈密顿(Hamiltonian)出发,利用格林函数方法求解其基态和低能激发态,对处于2ev的电子激发态进行了详细的讨论,并成功地解释了反射谱等光学特性。

The decarbonylation and the structure transformation of surface Pt3(CO)3(PPh3)4 complex supported on Al2O3 and TiO2 in vacuum or in CO were studied by electron spin resonance (ESR), UV-diffuse reflectance spectroscopy (DRS), infrared spectroscopy, and temperature-programmed decomposition (TPDE). For the complex supported on Al2O3, three ESR signals, which are similar to that of PPh3/Al2O3, are observed, implying that one PPh3 ligand of the complex is substituted by OH- or O2- on the surface of the support, and...

The decarbonylation and the structure transformation of surface Pt3(CO)3(PPh3)4 complex supported on Al2O3 and TiO2 in vacuum or in CO were studied by electron spin resonance (ESR), UV-diffuse reflectance spectroscopy (DRS), infrared spectroscopy, and temperature-programmed decomposition (TPDE). For the complex supported on Al2O3, three ESR signals, which are similar to that of PPh3/Al2O3, are observed, implying that one PPh3 ligand of the complex is substituted by OH- or O2- on the surface of the support, and Pt3(CO)3(PPh3)3(B)(B = -O- Al or HO-Al ) is formed. The surface compl-ex onAl2O3 is decarbonylated upon heating in vacuum. When the surface complex is heated in CO atmosphere, two terminal carbonyl bands appear, they are assigned to Pt(CO)2(PPh3) (B) and Pt(CO) (PPh3) (B)2 respectively. For the complex supported on TiO2, IR and TPDE spectra show that the transformation of surface complex involves decarbonylation and decomposition both in vacuum and in CO upon heating, four peaks are found and they are assigned to Pt3(CO)3-(PPh3)3(B), Pt(CO)2(PPh3)(B), Pt(CO)(PPh3)(B)2 and Pt(PPh3)(B)2(B = -O-Ti ) respectively.

用电子自旋共振、紫外漫反射谱、红外光谱和程序升温分解等法研究了Al_2O_3和TiO_2担载的Pt_3(CO)_3(PPh_3)_4络合物的表面结构和在真空及CO中的热分解。当络合物担载于Al_2O_3上时,其桥羰基和Pt—Pt骨架未发生明显变化,ESR谱表明络合物的一个PPh_3基被Al_2O_3表面的化学基团取代,形成了Pt_3(CO)_3(PPh_3)_3(B)(B=—O—Al或HO—Al)。在真空或CO中,表面络合物随温度升高而逐渐脱去羰基,分别出现相当于Pt(CO)_2(PPh_3)(B)和Pt(CO)(PPh_3)(B)_2的碳基吸收带。当络合物担载于TiO_2上时,在真空、CO或氦中升温时,结合物均发生分解而分别形成相当于Pt_3(CO)_3(PPh_3)_3(B),Pt(CO)(PPh_3)(B),Pt(CO)(PPh_3)(B)_2和Pt(PPh_3)(B)_2表面络合物。

The dynamic and equilibrium adsorption of H_2PtCl_6 on various aluminas were studied,and IRS and UV-Vis.DRS were used to characterizet hese supports before and after impregnation with H_2PtCl_6 solution.The data indicated that the uptake of H_2PtCl_6 on supports strongly depends on the Lewis acidity of alumina and that the rate of adsorption of supports with high adsorption capacity is controlled by pore diffusion.Relationships between uptake and acidity were interpreted in terms of active hydroxyl groups on...
