It was found that the geometries of the studied materials were significantly affected by the ring size and intramolecular charge transfer. The HOMO level, LUMO level, and band gap of the studied model compounds were well controlled by the acceptor strength. However, the electronic properties of the studied polymer showed a significant different trend with the acceptor strength due to the geometrical transformation. The model compound of EDOT-TP and T-TP has the aromatic geometry but is transformed to the quinoid geometry for large intramolecular charge transfer. The small bond length alternation and large acceptor strength in the EDOT-BDP polymer also results in the smallest Eg of 0.7 eV among the studied polymers.

我们发现环的大小以及分子内电荷转移对结构有很大的影响，而小分子的HOMO、LUMO和能隙受到电子受体强度所控制，然而，高分子的电子特性与其构成分子却有明显不同的趋势，这主要是由於分子结构的转变，如小分子EDOT-TP以及T-TP因分子内电荷转移，使其高分子结构由aromatic转变成quinoid；而EDOT-BPP因其键长改变量小和良好的电子受体强度，使其能隙仅0.7个电子伏特。

In previous studies, Cyclooxygenase-2(COX-2) is believed to be linked with inflammations and tumors. But in recent reports, COX-2 is found to play important roles in osteoblastic mechanotransduction and in bone remodification and resorptions in some ways. It was found that mechanical stretches, such as hydrostatic forces and pulsating fluid flow, could increase the expressions of COX-2 mRNA and then prostaglandins, and activate many signal pathways in osteoblasts.

环氧合酶-2(cyclooxygenase-2，COX-2)以往被认为与炎症、肿瘤等有密切关系，近年研究发现它在骨骼重建、骨质吸收以及成骨细胞力学信号转导中发挥着重要作用，主要表现为机械牵拉、流体力、节律性液体流(pulsating fluid flow，PFF)等机械刺激均能引起成骨细胞COX-2高水平表达，进而引起前列腺素(prostaglandins，PGs)量的增加，激活成骨细胞内多条信号传导通路。
