direct polymerization [33]. The procedure is useful

for the preparation of dissymmetric polymers. Fur-

ther compounds with amino groups and nitro groups

are 3-nitroaniline, 2-methyl-5-nitroaniline, and, 3-

nitromesidine, i.e., 2,4,6-trimethyl-3-nitroaniline.

14.2.4 Microwave Polymerization

Microwave-assisted polymer synthesis offers

unique advantages, such as shorter reaction times,

higher yields, limited generation of byproducts, and

relatively easy scale-up without detrimental effects

[34]. PAIs with a chiral nanostructure have been

synthesized by this method. To assess the efficiency

of microwave irradiation method together
