About

Jiwei Li is a remote sensing scientist, biological oceanographer, and computer scientist. His research explores interactions between human and natural systems, particularly at the land-ocean interface. He combines remote sensing with physically scalable analytical algorithms, big data analysis, cloud computing, and machine learning to understand the impacts of human activities on aquatic systems such as oceans, rivers, and lakes. His work aims to protect Earth's resources, including coral reefs, freshwater, and fish, and to promote a more sustainable future. Li holds a Ph.D. in Geosciences from the University of Massachusetts Amherst, where his dissertation focused on estimating colored dissolved organic matter in inland waters using water bio-optical properties and remote sensing. He also earned a master's degree in GIS and Remote Sensing from Capital Normal University and a bachelor's degree in Computer Science from Northwest University. His expertise areas include air quality, artificial intelligence, big data, biodiversity, biogeoscience, earth systems and climate science, geographic information science, machine learning, marine ecology, oceanography, remote sensing, water, watersheds, hydrology, and mapping. He is actively involved in research, teaching, and public work, and serves on the editorial board of the journal Remote Sensing.

  Abstract Stable and efficient deep‐blue organic light‐emitting diodes (OLEDs) are in high demand for display and lighting applications but are rarely reported due to their poor operational lifetimes. Herein, the study designs and synthesizes two novel N ‐heterocyclic carbene (NHC)‐based tetradentate Pt(II) complexes PtON5‐dtb and PtON5N‐dtb, and thoroughly investigate their electrochemical and photophysical properties. Functionalization of the NHC moieties can increase the metal‐to‐ligand charge…

  Abstract To realize low‐cost, efficient, and stable organic light‐emitting diodes (OLEDs) in future large area displays and lighting, the development of suitable solution‐processed functional materials is highly desirable. Herein, a series of efficient and stable OLEDs with an inverted device architecture is reported, employing both a vapor‐deposited phosphorescent aggregate emitter, i.e., Pd(II) 7‐(3‐(pyridine‐2‐yl‐ κ N)phenoxy‐ κ C)(benzo‐ κ C)([ c ]benzo[4,5]imidazo‐ κ N)[1,2‐ a ][1,5]naphthy…

• Ultrahigh Energy Gap Hosts in Deep Blue Organic Electrophosphorescent Devices

  2023-11-14 · 1 citations

  book-chapterOpen access

  The authors discuss the material design, and present device data for OLEDs employing UGHs. In addition to showing that UGH materials can be used to fabricate efficient blue OLEDs, we demonstrate that very high device efficiencies can be achieved in structures where the dopant transports both charge and excitons. To circumvent the limitations of carbazole-based hosts, we have studied a series of ultrawide energy gap hosts (UGHs). The materials have large HOMO to lowest unoccupied molecular orbita…
