Abstract
Metal–organic frameworks (MOFs) are promising electrochromic materials known for their rapid response speed and ability to transition through multiple colors. However, typical MOF films suffer from slow response times and poor stability due to inappropriate pore sizes, weak substrate interaction, and limited bond reversibility. This study addresses these challenges by modifying F-doped SnO2 with 4-mercaptobenzoic acid and fabricating Ni-IRMOF-74@MBA films using 3,3′-dihydroxy-4,4′-biphenyldicarboxylic acid. The optimized film exhibits a rapid response (1.9 s/2.0 s), high efficiency (331.0 cm2 C–1), and favorable stability (95.7% retention after 4500 cycles), transitioning from transparent to green at 0.8 V and deep-brown at 1.6 V due to Li+ interaction with the ligand. The resulting electrochromic device shows improved response (2.3 s/7.9 s) and stability (85% retention after 1200 cycles). This work presents a significant advancement in developing MOFs for electrochromic applications.

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
