金属酞菁是一种非常有用的颜料，但如果没有合适的官能团，在普通溶剂中几乎不溶。在本文中，我们报道了弯曲的聚芳族两亲物作为非官能化MPc和较大MPc衍生物（例如，CuPc、全卤化CuPc、Cu-萘、CuPc聚合物和双层MPcs）在中性水中的溶液。所得的MPc纳米复合材料显示出对热和pH变化的高稳定性。更重要的是，包封的MPc可以通过简单的方案在温和的条件下释放到本体溶剂中和玻璃或聚合物板上。
Metallophthalocyanines (MPcs) are very useful pigments but scarcely soluble without appropriate functional groups in common solvents. Herein, we report that bent polyaromatic amphiphiles act as excellent solubilizing reagents for nonfunctionalized MPcs and larger MPc derivatives (e.g., CuPc, perhalogenated CuPcs, Cu-naphthalocyanine, CuPc polymers, and double-decker MPcs) in neutral water upon encapsulation. The resultant MPc nanocomposites display high stability towards heat and pH change. More importantly, the encapsulated MPcs can be released by simple protocols under mild conditions both into a bulk solvent and onto glass or polymer plates.
