The opticallyactive metallo-supramolecular polymers were successfully synthesized via complexation of Fe(II) ions with new bis-terpyridines containing chiral tetra-ethylene glycol units at the ortho-position of the peripheral pyridine rings. In addition, we also revealed solvent and temperature effects toward assembly and dis-assembly behavior of polymers.
The chiral and amphiphilic aza-BODIPY dye (S)-1 exhibits kinetic-controlled self-assembly pathways toward three supramolecular polymorphs with distinct nanomorphologies and chiroptical properties. Temporal control of the kinetic transformation process from Agg. B to Agg. C leads to aggregate mixtures consisting of different ratios of Agg. B and Agg. C that show wavelength-tunable circularly polarized
手性和两亲性氮杂-BODIPY染料( S ) -1表现出动力学控制的自组装途径,形成具有不同纳米形态和手性光学性质的三种超分子多晶型物。 Agg 动力学转化过程的时间控制。 B到Agg。 C导致由不同比例的Agg组成的聚集体混合物。 B和Agg。 C显示波长可调的圆偏振发光。
