Thiol-capping of CdTe nanocrystals were prepared in aqueous solution. The emission wavelengths of CdTe nanocrystals could be tuned by the refluxing time. Bioinorganic conjugates between CdTe nanocrystals and BSA were formed via electrostatic/coordinate self-assembly. The photoluminescence intensity of the bioinorganic conjugates was improved obviously. BSA could stabilize the CdTe nanocrystals, and the bioinorganic conjugates at room temperature were stable for a long time. We also demonstrated that CdTe nanocrystals could be blocked with BSA and avoid the nonspecific adsorption.
A nonliquid crystal azobenzene polymer was prepared.The obtained films exhibit fast bending response at room temperature,which can improve the efficiency of the transformation of energy from light to mechanical energy.The surface structure of the relief gratings was investigated by atomic force microscopy.The depth of surface relief in a typical case is found to be around 94 nm.The product structures were characterize by UV light,1H NMR,AFM and Fourier transform infrared spectrum.
