In order to mimic this repair process of apoenzyme, we synthesized two model compounds, in which tryptophan and/or tyrosine was covalently linked to cyclobutane thymine dimer, and measured the splitting quantum yield of dimer under 295 nm light. By investigating the photosensitized splitting properties of the dimer, some new insights into the intramolecular electron-transfer process were gained.

为了模拟酶蛋白的这一修复过程，合成了色氨酸和/或酪氨酸与胸腺嘧啶二聚体共价连接的化合物，作为酶-底物复合物的模型，研究了它们在295 nm光照射下氨基酸残基光敏化二聚体裂解的性质，测定了二聚体裂解量子产率，获得一些新的结果并对其进行了分析。

In addition, the recombination for large numbers of charge carriers would occur in the volume or on the surface of TiO_2. Therefore, the extension of the photoactive wavelength region of TiO_2 into the visible region and improvement of quantum efficiency are desirable for popularizing more TiO_2 photocatalyst, especially under solar light for industrial areas or poor interior lighting illumination in living spaces.

但纳米TiO_2具有较宽的禁带宽度，只能吸收太阳光中5%左右的紫外线，而太阳光中近45%的可见光在处理污染物中却得不到有效利用，因此太阳能的利用率较低，这就限制了其实际使用范围；另外，TiO_2半导体载流子的复合率较高，因此量子效率较低。

TPA-PPV (M_W of 3000-4000 g/mol) is a good kind of polymeric light-emitting diodes material and has a high photoluminescent quantum yield, we prepared a series of TPA-PPV nanoparticles with diameters ranging from 20 to 100 nm by reprecipitation method.

The results indicate that the PPV oligomer with biphenyl bridge is a cross form between two chains and tortuose derivative in the same chain. It reduces molecular symmetry and weakens %π-π% stacking effect among conjugated molecules in solid. This is perhaps the important factor that light-emitting diodes can increase fluorescence quantum efficiency.

结果表明，联苯桥联后的PPV齐聚物在结构上形成了链间交叉链内扭曲的构象，这种交叉扭曲的构象降低了分子的对称性，减弱了共轭分子在固体中的π-π堆积作用，这可能是减少荧光猝灭效应，提高固体发光器件效率的重要原因。
