本文综述了聚甲炔链长、杂原子结构、取代基性质、电子不对称性、发色团相互作用、离子对结构、质子转移光化学反应以及浓度等因素对聚甲炔染料光谱发光性能的影响。在低极性介质中，包括聚合物基体，这些属性的特征进行了讨论。研究了聚甲炔的溶剂化变色和溶剂化荧光变色。花青的光谱发光性能的变化，在它们的结构和介质的性质，影响的主要因素被揭示。可能的应用聚甲炔的解决方案与光能的转换的各种问题进行了讨论。参考文献231篇。
The review considers the influence of the length of the polymethine chain, the structures of the hetero-radicals, the nature of substituents, electronic asymmetry, interactions of chromophores, structures of ion-pairs, photochemical reactions with proton transfer, and concentration, on the spectral-luminescent properties of polymethine dyes. The characteristic features of these properties in low-polarity media, including polymeric matrices, are discussed. Solvatochromism and solvatofluorochromism of polymethines are considered. Major factors influencing changes in the spectral-luminescent properties of cyanines, in relation to their structure and the nature of the medium, are revealed. Possible applications of polymethines to the solution of various problems connected with the transformation of light energy are discussed. The bibliography includes 231 references.
