Abstract The aggregate luminescence behavior of organic luminescent materials has been studied extensively. As a new kind nanomaterials, carbonized polymer dots (CPDs) not only inherit the stability and biocompatibility carbon materials, but also possess tunability, water solubility, high photoluminescence quantum yield rendering them strong candidate for next generation light‐emitting materials. Previously, people mainly understood its from perspective some mechanisms are still unclear. In this review, we discuss mechanism by referring to with emphasis on their aggregation behavior. Firstly, three representative phenomena briefly introduced. Chromophores present in CPDs elaborated further potential interactions between them, role crosslinked networks. On basis, special state summarized, relevant discussed detail consolidate statements.

Revealing the photoluminescence (PL) origin and mechanism is a most vital but challenging topic of carbon dots. Herein, confined-domain crosslink-enhanced emission (CEE) effect was first studied by well-designed model system carbonized polymer dots (CPDs), serving as an important supplement to CEE in aspect spatial interactions. The "addition-condensation polymerization" strategy adopted construct CPDs with substituents exerting different degrees steric hindrance. on structure luminescence properties have been systematically investigated combining characterizations theoretical calculations. Such tunable interactions dominated coupling strength luminophores one particle, eventually resulted modulated PL CPDs. These findings provide insights into structural advantages CPDs, which are general significance further development tailored properties.
