In this paper, we report six phosphorescent Cu(I) complexes with 1,10-phenanthroline-derived ligands and phosphorous ligands, including their synthesis, crystal structures, photophysical properties, and electronic nature. The Cu(I) center has a distorted tetrahedral geometry within the Cu(I) complexes. Theoretical calculation reveals that all emissions originate from triplet metal-to-ligand-charge-transfer excited state. It is found that the introduction of alkyl moieties into 2,9-positions of 1,10-phenanthroline is highly effective on restricting the geometric relaxation that occurs in excited states, which greatly enhances the photoluminescence (PL) performances, including PL quantum yield improvement, PL decay lifetime increase, and emission blue shift. © 2014 Elsevier B.V.

Financial risk is a problem the modern enterprises development must face, with the market economic system reform, the rapid development of information and science and technology and the current market environment enterprises face more complex, financial risk impacts the stable development of enterprises more serious. In this paper, by the concept and causes analysis of financial risk, we will further put forward relevant measures to avoid risk in financing from financial management, investment, capital recovery, income distribution four important aspects, to make enterprises develop better. © 2012 Springer-Verlag Berlin Heidelberg.

In recent years, our prison reeducation-through-labor work has made remarkable achievement, which is inseparable from the long-term unremitting effort of front-line police officers. Although our prison reeducation-through- labor work got good result, while give full recognition on the result, we should see that there are still some problems in the prisoners' reeducation-through- labor process. According to the analysis of the existing problems in the secure and stable work, and the potential threat to the security and stability of prison, this article did scientific and general exploration to solve the problems of the prison security, stability and quality of education and reform, having a strong reference value to strengthen the prison management, continuously improve the quality of education and maintain prison secure and stable development. © 2013 Springer-Verlag.

This article describes the illegal invasion of computer systems, mainstream means of hidden Trojan horse property, describe the characteristics of several types of malicious code, and stressed the importance of computer information system security. Describe the basic idea of the invasion of the system means, mostly utilize the loopholes of the software vulnerability or system loophole, or inject malicious code to the target system, and then elevated privileges to obtain information, or undermine the data of the system. List several elements of the computer information system security, and stressed the importance of cryptographic algorithm as the core of secure communication protocols in computer communications. Explain the characteristics of public key cryptography, introduce RSA encryption algorithm as the example of it. Through the analysis of the security elements, hold out the methods of precautions. © 2013 Springer-Verlag. Source

Since the economic reform in the last century, the people's living has undergone enormous changes. At the same time, the role of various social administrative subjects in public administration and socialization services is also increasingly important. Government functions gradually tend to be socialized in the operation and development process, implementing a series of changes in health care, transportation, health, education, environmental protection and other public welfare services. Social administration involved in the interests of the masses in the operation of the process. In order to protect the interests of the people are not violated, they would need a certain political and legal naturalization range which can ensure its legality and legitimacy. Government functions in the political and legal governance have become the priorities and hot spots of China's political reform, economic reform and social reform. © 2013 Springer-Verlag. Source
