Are organic semiconducting polymers a viable solution to biohybrids?

These include the low utilization of light energy, the inadequate selectivity of products, and the limited utilization of inorganic carbon/nitrogen sources. Organic semiconducting polymers offer a promising solution to these challenges by collaborating with natural microorganisms and developing artificial photosynthetic biohybrid systems.

What is polyaluminum chloride (PAC)?

Polyaluminum chloride (PAC) is a classic inorganic polymer material, which has the advantages of easy preparation, low cost, and high efficiency in the field of water treatment and other areas of environmental protection [1, 2].

Is PAC a polymer flocculation catalyst?

The literature also indicates that Al 13 has a molecular scale of 1–2 nm and has a high charge, which is considered to be the most stable active species in PAC. Thus, PAC as “inorganic polymer flocculation catalyst” demonstrated its structural characteristics in the organic synthesis reaction system.

What is polyaluminum chloride used for?

The classic inorganic polymer flocculant—polyaluminum chloride (PAC)—was used as an environmentally friendly, efficient, and recyclable catalyst in the synthesis of Bis (indolyl)methanes (BIMs) compounds for the first time. The strategy of catalysis is to use PAC as a Lewis acid, which contains different structures of Al–O polynuclear cations.

Which semiconducting polymers can be used for artificial photosynthetic biohybrid systems?

More semiconducting polymers, such as poly (3-hexylthiophene) (P3HT), polypyrrole (Ppy), and so on, need to be further developed and used for artificial photosynthetic biohybrid systems in the future, and more challenges need to be met.

Can PAC be prepared from aluminum chloride solution?

PAC can be prepared from aluminum chloride solution with the titration of various basification agents such as calcium oxide [16, 21], sodium hydroxide [, , ] and sodium aluminate .
