Formation of nanospheres that consist of π-conjugated dendrimers (phenylazomethine and carbazole) is reported. The nanospheres can be prepared by spin-casting a solution of dendrimers in a proper good/poor solvent mixture as kinetically trapped amorphous products. This method could be applied to metallodendrimer and fluorescent dendrimer. By controlling the kinetic process, the size of the spheres could be controlled and the fluorescent dendrimer sphere, with a few ¯m in size, displayed whispering gallery mode (WGM) photoluminescence.
