ABO3钙钛矿由于丰富的A、B位离子组合方式以及BO6八面体灵活多变的畸变方式（包括不同程度的倾斜、旋转、伸缩等），展示了各种各样的晶体结构与物理性质，是半个多世纪以来凝聚态物理和材料科学的重要研究对象。对于外层电子为3d3的过渡金属离子，因其半满的t2g轨道分布（接近球对称），具有这种电子分布的钙钛矿材料（譬如R3+Cr3+O3，R3+代表稀土离子），其BO6八面体畸变往往很小。特别是相比于具有...

在人体生理条件下(pH 7.4)，利用紫外光谱法和荧光光谱法研究了本实验室合成的柔红霉素衍生物DNR-D3与小牛胸腺DNA(ctDNA)的相互作用。实验发现，在ctDNA存在下DNR-D3的紫外吸收光谱发生减色效应且出现红移现象，这表明DNR-D3与ctDNA相互作用的结合方式以嵌插为主。通过20, 30，37 ℃条件下ctDNA与DNR-D3相互作用的荧光光谱，判断ctDNA与DNR-D3之间荧...
