The cover picture shows DNA strand displacement being accelerated by ultrafast photo‐crosslinking with 3‐cyanovinylcarbazole. The invader strand (red) containing ^CNVK, which can crosslink to a pyrimidine base in a complementary strand after a few seconds of photoirradiation, can crosslink to the template strand (blue) and push out the passenger strand (green). The rate of photo‐crosslinking is a key factor; the rate of DNA strand displacement can be accelerated by using ultrafast photo‐crosslinking and regulated by photoirradiation energy. More information can be found in the communication by K. Fujimoto et al. on page 1984 in Issue 20, 2017 (DOI: 10.1002/cbic.201700430).

封面：使用超快DNA光交联技术促进DNA链置换的光化学加速（ChemBioChem 20/2017）

封面图片显示了与3-氰基乙烯基咔唑的超快速光交联加快了DNA链的位移。含有^CNV K的入侵链（红色），可以在几秒钟的光照射后交联到互补链中的嘧啶碱基上，可以交联至模板链（蓝色）并推出过客链（绿色）。光交联的速率是一个关键因素。通过使用超快速光交联可以加快DNA链置换的速率，并通过光辐射能对其进行调节。可以在K. Fujimoto等人的来文中找到更多信息。关于在第20期，2017页1984（：10.1002 / cbic.201700430 DOI）。
