From: Enabling nonconjugated polyesters emit full-spectrum fluorescence from blue to near-infrared
A, B Normalized PL spectra of P2-aTEA in solid and DCM solution, respectively, at λex = 360 nm. The concentration of P2-aTEA in DCM is 10−1 M. C Plots of relative PL intensities of blue PL/NIR CL versus contents of TEA for P2-aTEA in both solid and DCM of 10−1 M at λex = 360 nm. D PL spectra of P2-5.0TEA in DCM solution of 10−1 M. E Concentration-dependent PL spectra of P2-5.0TEA in DCM at λex = 360 nm. Concentration is from 10−5 to 10−1 M. F Plots of relative PL intensities of blue PL, red CL, and NIR CL versus contents of TEA for P2-5.0TEA in DCM of 10−1 M at λex = 360 nm, respectively. Concentration is from 10−5 to 10−1 M. G Fluorescence photographs and chemical structures of P2-aTEA in solid powders taken under 365 nm UV light.
