Abstract
The luminescent properties of an organic dyad that combines two different luminophores, hydroxy-substituted 2,4,5-triarylimidazole and 8-azomethine-7-hydroxycoumarin, in its molecule have been studied in seventeen polymer matrices obtained by photocuring, which are represented by linear poly(meth)acrylates differing in the amount of hydroxyl groups and acrylic network polymers differing in the nature of crosslinking oligomeric blocks. The dependence of the luminescent properties of materials on the wavelength of excitation light, as well as on the presence and amount of hydroxyl groups in polymers; the presence of urethane groups, ether bonds, and aromatic moieties (individually or in combination); and flexibility and conditional polarity of the matrix, has been established.

Abstract—
Solid dispersions based on acyclovir and polysaccharides (starch and sodium carboxymethylcellulose) have been prepared by means of mechanochemistry. Mechanical co-processing of the drug and the polymers in a ball mill, an extruder, and a pulse mechanical action cell has led to amorphization of acyclovir, followed by its uniform distribution in the polymer matrix. A set of the IR and UV spectroscopy, DSC, and X-ray diffraction analysis data has revealed the presence of intermolecular interactions between the polysaccharide matrix and the drug. The obtained materials can be considered as potential system for further investigation as solid formulations of acyclovir with improved bioavailability.
摘要--通过机械化学方法制备了基于阿昔洛韦和多糖（淀粉和羧甲基纤维素钠）的固体分散体。在球磨机、挤压机和脉冲机械作用池中对药物和聚合物进行机械共处理后，阿昔洛韦发生了非晶化，随后均匀地分布在聚合物基质中。一组红外光谱、紫外光谱、DSC 和 X 射线衍射分析数据显示，多糖基质与药物之间存在分子间相互作用。所获得的材料可被视为具有进一步研究潜力的系统，作为阿昔洛韦的固体制剂，可提高其生物利用率。

Abstract
The development of organometallasiloxane chemistry from first polymeric systems to individual organometallasiloxanes and functional oligomeric compounds is considered. The structural diversity of organosilicon precursors and the variability of metal-containing components are presented. Synthetic approaches are considered in detail, including those that allow targeted production of organometallasiloxanes of a certain structure. Using the example of organometallasiloxanes synthesized from trifunctional organoalkoxysilanes, methods for the synthesis of unique stereoregular functional cyclosiloxanes and their derivatives are highlighted. Considerable attention is given to the applied aspects of various structure organometallasiloxanes and their derivatives. The state of the art of the chemistry of organometallasiloxanes and their further evolution are evaluated critically.
