HPLC analyses were carried out as described for different compounds. HR-ESI-MS was performed on an Agilent 1260 HPLC/6520 QTOF-MS instrument (Santa Clara, CA, USA) with an electrospray ionization source. NMR analysis was performed at room temperature on a Bruker Advance 500 NMR spectrometer (Billerica, USA).

In the section, PAM, PAD and TPADs after purification were ground into powder for characterization analysis. The FTIR spectra of the polymers were acquired using KBr pellets on a 550 Series II infrared spectrometer (Bruker Company, Switzerland) with wave numbers from 500 to 4000 cm⁻¹. The ¹H NMR of the polymers were obtained by Advance-500 NMR spectrometer (Bruker Company, Germany) in deuterium oxide (D₂O) as a solvent with tetramethylsilane as an internal standard. The thermal stability (TG/DSC) of the polymers were determined by a TG/DSC/1100LF instrument (Mettler, Switzerland) under argon atmosphere from 20 °C to 600 °C at a heating rate of 10 °C min⁻¹. The SEM images of the polymers were acquired by MIRA3 LMH (Tescan Trade, Shanghai) instrument to investigate their surface morphology. The BET surface areas were measured on ASAP 2020 M+C (Micromeritics, American).

All reagents were commercially available and used as supplied without further purification. Ethyl ether, triethylamine and dioxane are re-steamed according to the solvent manual. ¹H NMR and ¹³C NMR spectra were measured in CDCl₃ at ambient temperature using a Bruker Advance 500 NMR spectrometer (operating at 500 MHz for ¹H and 126 MHz for ¹³C). High resolution mass spectrometry (HRMS) was obtained by Thermo Fisher Scientific LTQ FTICR-MS and Thermo Scientific Q Exactive HF Orbitrap-FTMS. All photophysical measurements were performed in standard quartz cuvettes (1 cm × 1 cm cross-section). Luminogen-doped PMMA (polymethyl methacrylate) film was prepared by dissolving 2 mg of a luminogen compound and 100 mg of PMMA in 5 ml of specpure DCM followed by casting the resulting solution onto the surface of a quartz cell. UV-visible absorption spectra were recorded on a HITACHI UH5700 UV-visible spectrophotometer. The fluorescence, phosphorescence spectra, lifetimes and fluorescence quantum yields were recorded on a spectrofluorometer Edinburgh FLS1000. Thermogravimetric data were recorded on TGA5500.

The 1 H and 13 C NMR spectra were obtained on a Bruker Advance 500 NMR spectrometer. The 13 C spectra were recorded using proton decoupling techniques (Waltz-16) taking advantage of the nuclear Overhauser effect. The methyl signal of tert-butyl alcohol was used as the internal reference for 1 H (δ 1.3) and 13 C (δ 31.2) relative to TMS.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
