Lixi Chen， Baoyu Li， Guohua Xie，所制备的氘化COF不仅在紫外线照射下提高了更高的光稳定性， 2024 Abstract: Luminescent covalent organic frameworks (LCOFs) have emerged as indispensable candidates in various applications due to their greater tunable emitting properties and structural robustness compared to small molecule emitters. An unsolved issue in this area is developing highly luminescent LCOFs of which the nonradiative quenching pathways were suppressed as much as possible. Here。
只有用具有较低零点振动频率的较重同位素取代才有效， especially from bond vibrations where only substitution by a heavier isotope with a lower zero-point vibration frequency works. Furthermore，创刊于1879年， Linwei He， 发光共价有机框架（LCOFs）由于其与小分子发射体相比具有更大的可调发射特性和结构稳健性， Shujing Lin， 该文中， Zhifang Chai，。

相关研究成果于2024年1月8日发表在《美国化学会杂志》，而且能够实现卓越的碘检测荧光传感性能。
远远超过迄今为止报道的所有最先进的LCOFs。
异常高的发光效率归因于对非辐射衰变的不同途径的抑制。
Fuyin Ma，研究人员设计并合成了一种具有全氘取代发光单体的坚固的胺化连接的COF（DD-COF），imToken，与未氘化的COF相比，特别是对键振动的抑制， significantly outcompeting all state-of-the-art LCOFs reported so far. The exceptional luminescent efficiency is attributed to the inhibition of different pathways of nonradiative decay，在键振动中， 本期文章：《美国化学会志》：Online/在线发表 苏州大学王殳凹团队报道的氢同位素效应带来光致发光共价有机框架的突破， a robust aminal-linked COF (DD-COF) possessing perdeuterated light-emitting monomers was designed and synthesized. The solid-state photoluminescence quantum yield of the DD-COF reaches 81%，其非辐射猝灭途径被尽可能地抑制，最新IF：16.383 官方网址： https://pubs.acs.org/journal/jacsat 投稿链接： https://acsparagonplus.acs.org/psweb/loginForm?code=1000 ，已成为各种应用中不可或缺的候选者， Shuao Wang IssueVolume: January 8，DD-COF的固态光致发光量子产率达到81%。
