In addition, a chalcone derivative was synthesized as fluorescent and colorimetric chemosensor for anions such as F~- and AcO~-.5. Mesoporous SQ/SBA-15 on the basis of the interaction of squaraine dye and mercaptol was designed and synthesized.

设计合成了一个查尔酮化合物5，加入碱性较大的阴离子后，紫外可见吸收光谱和荧光光谱均发生变化，有望发展为荧光和生色双功能阴离子传感器。5。

Three expression vectors containing mutant gfp which were truncated from 3′ termine were constructed in the present paper.The mutation gfp with different length under the control by T 7 promoter were expressed in E. coli BL21 cells.

本文将突变型 gfp3′末端不同程度地截短，构建成表达载体，在大肠杆菌 BL 2 1中表达了不同长度的绿色荧光蛋白，当其生色基因中 65位 Ser点突变成 Thr，则 GFP的激发波由 396nm增至 4 70 nm，不用 UV激发，仅在自然光源下就可看到强烈的绿色荧光，发光强度增加 6倍，若从 3′端截短 12个氨基酸密码，对发光无影响，但截短 75个氨基酸密码，则激发波长降到 360 nm，发光强度减少 12倍。
