A colloidal solution of QRs and DiRs in chloroform (Vekton, Russia) was prepared to measure the MCD and absorbance spectra. MCD and absorbance spectra were measured on a Jasco J-1500 circular dichroism spectrophotometer (Tokyo, Japan) equipped with electromagnetic unit MCD-581 at a field strength of ±1.5 T at room temperature.
Chloroform
Manufactured by Vekton
Sourced in Sao Tome and Principe
Chloroform is a colorless, volatile liquid chemical compound that is used in various industrial and laboratory applications. It has a characteristic sweet odor. Chloroform is primarily used as a solvent for fats, oils, rubber, and other organic substances. It is also used as an intermediate in the production of other chemicals.

Thermoplastic PLA—poly(lactic acid), 4032D (with about 2% of D-lactide) with molecular weight (Mw) of 1.7 × 105 g/mol was procured from Nature Works (Minnetonka, MN, USA). Low molecular weight component (Figure 1 ) 5,10,15,20-tetrakis(4-n-hexyloxyphenyl)porphyrin (TPP4OC6) synthesized as described in [26 (link)].
Film samples of PLA–TPP4OC6 with a diameter of 90 mm and a thickness of 100–120 µm were obtained by casting from a solution (Scheme 1 ). The solvent was chloroform (Vekton, Russia). PLA was dissolved in chloroform and heated to a temperature of 59 ± 1 °C. After cooling the PLA solution to 35–38 °C, the porphyrin solution was added. The resulting solution was mixed and poured into Petri dishes. The content of TPP4OC6 porphyrins in the film composites was 0.2–0.5 wt %.

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.
