Isocyanate-free synthesis of high mol. weight polyurea (PUrea) is a challenging and important area of research, considering the health and safety concerns related to isocyanates and a wide range of day-to-day uses of polyurea. In this article, an isocyanate and phosgene-free synthesis of high mol. weight fluorescent polyurea (Mn > 150,000) is reported via triazolinedione (TAD)-indole click reactions. Both the bisTAD and bis-indole monomers are synthesized from di-Ph carbonate using solvent-free reactions. The synthesis of polyurea is finished within 15 min under ambient conditions, without the use of any additives and catalysts, which is a remarkable advantage in comparison to all other reported methods in the literature. The mol. weight (Mn) of the polyurea can be defined as either very high mol. weight >150,000 g/mol or low mol. weight ∼ 3500-4000 g/mol via choosing a suitable solvent for the polymerization reaction. This approach is also useful for polyurea-based hydrophobic coatings as evidenced by the water contact angle anal. The indole-derived aromatic moieties introduced within the polymer backbone; impart photoluminescence properties and polymers show excitation-dependent emission behavior. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Synthetic Route of C13H10O3).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C13H10O3
