Double wall glass

Deionized water (DIW) purified by a Milli-Q 50 system (TKA, Germany) was employed in all experiments. Acetone, sodium hydroxide (NaOH), potassium phosphate dibasic (K ${}_2$ HPO ${}_4$ ), sodium chloride (NaCl), sulfuric acid ( $97\%$ H ${}_2$ SO ${}_4$ ), D(+)-sucrose, ethanol, and aniline ( $99\%$ C ${}_6$ H ${}_5$ NH ${}_2$ ) were bought from Merck. The nitrogen and oxygen gas $6.0$ purity bottles were provided by Messer. The multimode optical fiber of 400 μm diameter was purchased from Thorlabs. The Pasteur glass pipettes, the double wall glass, and the magnetic stir plate were supplied by VWR.

All the reagents used in this work were of analytical grade (99.99% purity, unless otherwise specified). Ultra-clean deionized water (DIW), purified by a TKA Milli-Q 50 system, was consistently used throughout the experiments. Acetone, sulfuric acid (97% H₂SO₄), D( +)-sucrose, ethanol and aniline (99% C₆H₅NH₂) were supplied by Merk. The nitrogen and oxygen 5.0 purity gas bottles were acquired from Messer. The TEQS multimode FO of 400 μm diameter was provided by Thorlabs. The additional tools used in the aniline polymerization protocol, such as the Pasteur glass pipettes (2 mL capacity, 230 mm length), the double-wall glass (diameter 55 mm, capacity 150 mL, height 85 mm) and the magnetic stir plate were obtained from VWR. The TC120 heated circulating bath was purchased from Grant Instruments.
