A water‐soluble photoactive azaanthracene derivative was synthesized. Its structure was determined by single‐crystal XRD analysis. Then, [4+4] photodimerizations were studied both in solution and in the solid state. Owing to the suitable preorganization of the monomers, solid‐state photodimerization was realized in quantitative yield with high selectivity.

基于[4 + 4]环加成的氮杂蒽衍生物的固态光二聚化

合成了水溶性光敏氮杂蒽衍生物。它的结构是通过单晶XRD分析确定的。然后，在溶液和固态下都研究了[4 + 4]光二聚化。由于单体的适当预组织，实现了固态光二聚化的定量收率和高选择性。
