1. Transition Metal Cluster Chemistry Synthesis and characterization of acetylide, alkylidyne, carbido and oxo- ligands containing carbonyl cluster compounds. These studies are focused on the exploration of their solid-state crystal structures, solution dynamics, and the possible application as efficient catalysts or as templates for assembling small organic intermediates. 2. Materials Chemistry Chemical Vapor Deposition. Design and preparation of a variety of highly volatile transition-metal or main-group complexes useful in depositing thin film materials such as Co, Cu, Pd, Ir, Ru or Os, metal fluorides, oxides and sulfides such as BaF2, SrF2, Ga2O3, In2O3, RuO2, IrO2, CdS and ZnS or even mixed metal alloys such as Ru/Pt, which is a highly effective catalyst for DMFC applications. In addition, we are also interested in the growth of patterned nano-materials on various substrates using our custom-made CVD source reagents. Luminescent Organometallic Compounds. This section of work is probably the most significant research for Prof. Chi in terms of the potential for industrial applications and led to the issue of three patents and several more pending. He was the first to prepare the highly luminescent Os(II) b-diketonate complexes (Chem. Commun. 2003, 3046), which was highly praised by Platinum Metals Reviews (2004, 48, 12) for their ingenious molecular designs, and to develop the blue-emitting Os (II) phosphorescent materials (Organometallics 2003, 22, 4938) at the time when the fabrication of blue phosphorescent OLEDs is just at dawn. As a result, the second paper was selected as the most accessed article on Organometallics in 2003 and 2004, as well as the second most accessed paper in the first half-year of 2005. Six months later, his work on red-emitting osmium (II) phosphorescent complexes eliminated the long-time dominance of Ir(III) based complexes in fabricating red-emitting OLEDs and set up the new records for the device performances (Organometallics 2004, 23, 3745). Not surprisingly, this paper was selected as the most accessed paper in the category of Technical Note, Commentary and Review in 2004. Furthermore, he also completed the synthesis of neutral Ru(II) emitters, despite of the skepticism that the weaker ligand field strength as well as its less efficient spin-orbit coupling of Ru(II) element would prohibit their application for making high performance OLEDs. Nevertheless, good progress was achieved and these are apparently credited to the rational ligand design via the standpoint of fundamental chemistry and photophysics (Adv. Mater. 2005, 17, 1059). In the mean time, he has started collaboration with Dr. Chin-Ti Chen of Academic Sinica, focusing on the preparation and utilization of blue-emitting iridium (III) complexes. In short, they have finished the fabrication of the high efficiency blue phosphorescent OLEDs, using direct physical vapor deposition of the tailor-made iridium emitting complexes and the carbazolyl substituted tetraphenylsilane as the host material. The paper appeared in the prestigious material journal (Adv. Mater. 2005, 17, 285) was selected by its editorial staffs as the second most downloaded article in the year of 2005. Moreover, he also joined another collaborator (Prof. Ching-Fong Hsu of National Chiao Tung University) and took part in the investigation using fluorene-based copolymer for preparation of PLEDs (Macromolecules 2005, 38, 9028) and white-emitting OLEDs (J. Mater. Chem. 2006, 16, in press). The first part of their endeavors was featured by an article (Research News) in the monthly magazine (MaterialsToday, December, 2005), while the second was nominated as the Hot Article of that journal. Finally, in recognizing his outstanding contribution in this fast growing OLEDs research area, he was invited to write (i) a feature article, which will be published on a WILEY-VCH book “Highly Efficient OLEDs with Phosphorescent Materials”, (ii) a Microreview Article (Eur. J. Inorg. Chem. 2006, 3319; SCI IF ~ 2.51) which was rated as the most download article in the period of August and September, as well as a (iii) a Concept Article on “Phosphorescent Dyes for OLEDs”, see: Chem. Eur. J. 2007, 13, 380. (SCI IF ~ 4.91). Luminescent Quantum Dots. Chi and Pi-Tai Chou’s have developed a conceptual photodynamic therapy (PDT) system with dual functions. Firstly, it has a high enough emission from the luminescent CdSe/ZnS quantum dot for use in medical imaging. Secondly, the iridium phosphorescent complexes are positioned in a way that enables them to sensitize oxygen molecules to produce a toxic singlet oxygen, on exposure to light as an alternative method for destroying cancer cells (Chem. Commun. 2006, 615). This work was cited by the RSC Publishing “Chemical Technology” as the application highlights “Hot-Article” on February 15, 2006. From January to April, 2006, this article was amongst the top ten accessed on the web from the online version of Chemical Communications
