Abstract

The polymerization mechanism and the identification of key oligomer intermediates during the thermal condensation of benzoguanamine (BG) remain unclear. Herein, we report a novel mixed thermal condensation strategy using BG and a pre-synthesized dimer to selectively synthesize the trimer (BG)3 with a significantly enhanced yield. Comprehensive characterization techniques confirm the formation of a linear molecular structure for (BG)3. Notably, (BG)3 exhibits a high molar absorption coefficient, approximately double the dimer and 4-fold greater than the monomer. Notably, (BG)3 demonstrates crystallization-induced phosphorescence (CIP) with a lifetime of 514.9 μs in the crystalline state at room temperature.

具有结晶诱导磷光的线性杂芳三聚体的可扩展无溶剂合成
目前尚不清楚苯并鸟胺(BG)热缩聚过程中的聚合机理和关键低聚体中间体的鉴定。在此,我们报告了一种新的混合热缩合策略,利用BG和预合成的二聚体选择性合成三聚体(BG)3,并显著提高了产率。综合表征技术证实(BG)3形成线性分子结构。值得注意的是,(BG)3具有较高的摩尔吸收系数,大约是二聚体的两倍,是单体的4倍。值得注意的是,(BG)3在室温结晶状态下表现出结晶诱导磷光(CIP),其寿命为514.9 μs。

期刊介绍: Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
