  本发明涉及铂(II)四齿ONNO络合物发光材料、制备方法及其在有机发光二极管中的应用。具有式I化学结构的铂(II)四齿联吡啶二酚ONNO络合物发光材料，可制造发射纯红色光的有机发光二极管。本发明的发光材料，由于左侧末端苯酚基与苯并呋喃相连，因此其比没有苯并呋喃基团的联吡啶二酚ONNO‑Pt(II)配合物的发射光谱要红移，而在右侧末端苯酚基环上引入了B基团，有效地增加了铂(II)络合物的抗聚集性能，自淬灭速率常数较低，且在一定掺杂浓度范围内可保持深红光发射色纯度和较佳的发光效率，更加适用于工业制备系统。

• Culture wars in the classroom: Prospective teachers question science

  Does studying about the nature(s) of science contribute to a prospective teachers' effectiveness as a science teacher? This research grew out of a course created by a science educator and historian of science who believed prospective teachers needed more complex understandings of the cultural wars surrounding science. The research team consisted of five prospective teachers who participated in the course as well as the two instructors. This paper describes the experience of participating in the course from both perspectives. We argue that studying the cultural wars over science contributes to prospective teachers' professional growth as much because the course elicits tacit beliefs about school science as it introduces more complex understandings of science. We found that prospective teachers' tacit beliefs about school science were their greatest barrier to developing more complex understandings about the nature(s) of science. We contend that willingness to grapple with complexity and developing a professional identity by locating oneself in the conversations about the nature(s) of science are better criteria for determining the professional growth of prospective teachers than knowledge measures. Finally, we argue that prospective teachers should be viewed as professionals who are responsible for finding their own voice, making their own decisions, and considering the consequences of their beliefs on their practice. This study raises questions critical to teacher education programs for prospective teachers and teacher-educators alike. (C) 2000 John Wiley & Sons, Inc.

  The invention relates to a platinum (ii) tetradentate onno complex luminescent material, preparation method and application thereof in organic light emitting diode. A platinum (II) tetradentate pyridine diphenol ONNO complex light-emitting material having the chemical structure of Formula (I) can be used for manufacturing organic light-emitting diodes emitting pure red light. The light-emitting material of the invention, because the end of the left side thereof is connected to benzofuran, has more red shift than the emission spectrum of the bipyridyl phenol ONNO-Pt(II) complex without a benzofuran group, and the anti-aggregation performance of the platinum(II) complex is effectively increased, as a B group is introduced on the phenolic ring on the right side thereof, so the self-quenching rate constant is low, and the color purity emitting deep red light and better luminous efficiency can be maintained in a certain range of doping concentration, which is more suitable for industrial preparation systems.
