英文摘要：

The experimental and theoretical progress on investigations and application of typical DNA molecular light switch Ru（Ⅱ） polypyridyl-type complexes [Ru（phen）2-（dppz）]^2＋ over the last 20 years was reviewed.The structural characteristics of the complex,the mechanism of bonding with DNA,the pattern of bonding and the disputes on hotspots relating to these complexes were also referred to.Furthermore,the application of the complex in structural identification and quantitative analysis of DNA was also mentioned.Based on the above understanding,this article proposes future research orientations on the DNA molecular light switch ruthenium complex.
