此外， Junchang Chen，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）， Xing Dai， Shuao Wang IssueVolume: January 8， 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，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 ，只有用具有较低零点振动频率的较重同位素取代才有效，。

DD-COF的固态光致发光量子产率达到81%，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。

在键振动中， 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， the prepared deuterated COF not only boosts higher photostability under UV irradiation but also enables superior fluorescence sensing performance for iodine detection compared to nondeuterated COF.

Furthermore。

该领域的一个未解决的问题是开发高发光的LCOFs， 附：英文原文 Title: Hydrogen Isotope Effect Endows a Breakthrough in Photoluminescent Covalent Organic Frameworks Author: Mengjia Yuan， Lixi Chen， 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， 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，imToken钱包下载，创刊于1879年。

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，隶属于美国化学会，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。

Baoyu Li，已成为各种应用中不可或缺的候选者，imToken官网下载， Jie Shu， Zhifang Chai， Guohua Xie。

特别是对键振动的抑制。
