通过使用双模式原子力显微镜（AFM），我们揭示了第一次的结构J聚集体的pseudoisocyanine氯化物（PIC-Cl）染料在云母/溶液界面的PIC-Cl水溶液。J聚集体是PIC-Cl分子多层膜中的叶状岛。还揭示了J带所需的聚集体的最小尺寸。染料分子通过Volmer-Weber型生长过程在云母/溶液界面生长成J聚集体。
By using tapping-mode atomic force microscopy (AFM), we revealed for the first time the structure of J aggregates of pseudoisocyanine chloride(PIC-Cl) dyes at a mica/solution interface in an aqueous PIC-Cl solution. The J aggregates were leaf-like islands in multilayers of PIC-Cl molecules. The minimal size of the aggregate necessary for the J band was also revealed. Dye molecules grow into the J aggregates at a mica/solution interface by a Volmer-Weber type growth process.
