Despite its many advantages, PCB also has some limitations.
One of the main challenges in its synthesis is the high cost of the starting materials, such as 9-phenylcarbazole, which can be expensive and difficult to obtain.
Additionally, the purification and isolation of PCB can be challenging, as it is often impure and occurs as a mixture of several isomers.

Another limitation of PCB is its relatively poor stability in air and light.
This can lead to degradation and loss of efficacy in applications, such as OLEDs, where the material is exposed to air and light.
To overcome this limitation, various modifications and derivatizations of PCB have been developed, which improve its stability and lifespan.

In conclusion, (9-phenyl-9H-carbazol-2-yl)boronic acid, or PCB, is a versatile and valuable building block for the synthesis of a wide range of organic compounds, materials, and chemicals.
Its ability to form stable complexes with metals and other ligands makes it an important tool in the fields of coordination chemistry, organic electronics, and materials science.
Despite some limitations, such as high cost and instability, PCB remains a popular and valuable compound in the chemical industry.
