摘要: The differences in self-organization behavior novel 100% pyrene labeled comb methacrylate polymers probed as a function of their varied origins excimer formation are presented. different structural variations the included presence or absence hydrogen bonding interactions form urethane linkages, short long alkyl spacer segments separating units from polymer backbone and linear versus kinked linkage. effect variable concentration temperature on chemical shift NH proton linkage was using 1H NMR experiments conducted at temperatures varying 25 to 70 °C two concentrations (2.5 mmol) DMSO-d6 solvent. photophysical properties dilute DMF solutions were investigated by steady state emission, fluorescence decay studies, time-resolved emission spectra (TRES), studies. It observed that poly(PBH) having n...
