  Synthesis of DNA with Spirobenzopyran as an Internal Covalent Modification

  摘要：

  通过两种不同的合成策略，光致变色螺吡喃被作为内部修饰引入到寡核苷酸中：第一条路线是将螺吡喃膦酰胺合成作为DNA构建模块，而第二条路线则采用了后合成“点击”型连接反应。在双链DNA中，色素的光诱导开环未能实现。

  CO₂ Triggering and Controlling Orthogonally Multiresponsive Photochromic Systems

  摘要：

  We report a new generic method of reversibly controlling the photochromism of spiropyrans. It was found that the photochromic effect of spiropyrans can be reversibly switched on and off by addition and removal of carbon dioxide (CO2) to spiropyran in alcohol solutions containing an amidine (i.e., DBU) that acts as a CO2 sensitizer. Spiropyrans are not photochromic in the presence of DBU but photochromic when CO2 is subsequently added to the solution. The CO2 is readily removed by inert gas bubbling, thus allowing facile activation and deactivation of the photochromic effect. Carbon dioxide, without the presence of the sensitizing amidine, had no effect on photochromism of the spiropyrans. Other photochromic dyes classes such as spirooxazines and chromenes are not affected by this CO2/DBU stimulus. As a result, orthogonal activation of mixtures of spirooxazines and spiropyrans was achieved to provide four color states (clear, yellow, green, and blue) by varying the combinations of the stimuli of UV, visible light, CO2, and CO2 depleted. This finding now permits the many applications using spiropyrans to be CO2 responsive.

  The synthesis of spiropyrans was improved significantly with use of ultrasonic radiation. To show the broad applicability of this methodology a range of spiropyrans were prepared which are equipped with iodo, hydroxyl, ethinyl, or azido groups as potential building blocks for conjugation to functional π-systems or biopolymers. Representatively, the conjugation chemistry was demonstrated for the preparation
