The principle of self-organization for the creation of functional units and the importance of lyotropic liquid crystals for the life sciences were reviewed. They are aprerequisite for the development of life and the creation of cell function. In macromolecular materials science, this concept of function th rough organization led to the development of new liquid crystallinem aterials. The self-organization of molecules leads to supramolecular systems and is responsible for their functions. From the view point of macromolecular materials science, we try to combine these two different fields, especially hope to stimulate their interaction and joint treatment. The supramolecular systems of liquid crystals,biomembranemodel, macromolecular liposomes and their applications to chemistry and biological medicine were reviewed. If the concept of bilayer assemblage can be extended more generally so as to include organic media, a wholly new branch of chemistry will emerge.

Glycobiology is the last important frontier in biochemistry. Complexity of carbohydrate research is due to the variety of the structure. In last few years, the determination of carbohydrate structure, especially the carbohydratemoiety of glycocon jugates has been developed rapidly. On the other hand, owing to complexity of structures, carbohydrates become biomolecules carrying large amounts of information. As informational molecules, carbohydrates play essential roles in living organisms, including determination of antigenecity of molecules and phenotype of cells, recognition in many physiological and pathological events, and as signals of dynamic regulations and of regulation on time and space.

The design and synthesis of small molecule modulators that can modulate the signal transduction process in CNS are anurgent task for brain chemistry. This paper describes the role of and the new challenge for organic chemistry in the development of brain chemistry by using the syntheticmodulators of glutamate receptor and its subtypes, protein kinase C and its isoenzymes as examples.

The fluorescence probe technique used in the filed of polymer science was introduced in this article from both theoretical and practical points. The photochemical and photophysical behaviors of fluorescence probe compounds have been discussed, and the study of the characterization of polymerst ructures as well as the problem of dynamic process of polymer have also been discussed. In addition, the molcular movement, energy transfer and the measurement of free volume in polymers were included as typical examples

Photochemistry of photo reaction intermediates and upper excited states is a new research area, which has been developed since them iddle of 1980's. One of the most important method used in the research is two-step two-laser technique. In this review , the emphasisis on the presentation of new concepts and theories, novel reactions and techniques. The following contents are comprised in the present paper: fluorescent and absorption spectra, intramolecular and intermolecular reactions of photo reaction intermediates,photophysics and photochemistry of upper excited triplet states, the application of two-step two-laser technique in high－tech new materials, such as those used for optical information storage.

The study of single layer of transition metal disulfides is a new developed research field in recent years. The motivation comes from different considerations. In the view of materials and solid state chemists, the single layer of transition metal disulfides provides a new synthesis route to novel solid state compounds with designed and distinctive structures. This paper reviews recent development of single layer of transition metal disulfides.

A review of thermodynamic study for electrolyte solution in recent years is presented from three aspects,i.e., traditional solution theory or semiempirical model, advanced statistical mechanics theory and molecular simulation. It is pointed out that the main tendency of this study is gradually turned from the traditional solution theory or semiempirical model to statistical mechanics theory , from primitive to nonprimitive electrolyte model, in o rder to estab lish the mo lecu lar thermodynam ic model at h igh level,which can predict them acroscopic thermodynamic properties of electrolyte solution system from the microscopic molecular and ionic parameters.
