Luminescent micro and nanogel formation from AB3 type poly(aryl ether) dendron derivatives without conventional multi-interactive gelation motifs

摘要: We report the synthesis, gelation and photophysical properties of luminescent AB3 type poly(aryl ether) dendron derivatives in absence conventional multi-interactive motifs. The process is controlled through employing partial polar solvent milieu, which significantly enhances propensity π–π interaction between aryl units present system. self-assembly leads to unprecedented entrapping molecules fibrillar arrangement units. strategy was further utilized prepare an excimer based photoluminescent gel incorporating anthracene dendrons. close proximity renders formation excimers at room temperature, resulting emission bright green light from gel, upon UV excitation. study suggests that size packing self-assembled fibre can be by generation functional groups dendron. Furthermore, envisages easy approach generate fluorescent Low Molecular-mass Organic Gelator (LMOG) poly cyclic aromatic hydrocarbon dendrons, since largely guided interactions.
