Luminescent Cyclometalated Diimine Platinum(II) Complexes Photophysical Studies and Applications... 

A number of platinum diimine-dithiolene complexes display long-lived solution and solid-state luminescence in ambient conditions and in frozen solvent glasses. A linear correlation has been found between emission energies and the difference in the ground-state redox potentials. These results provide the tools for tuning and systematically controlling... 

The use of fluorescent organometallic complexes to label biological substrates is beginning to provide some exciting alternatives to the more traditional organic dyes [126], with suitable iridium [127-129], rhodium [130], platinum [131], rhenium [132-135] and osmium [136] examples having recently been reported. The Re diimine wires (13g and 13h, Fig. 13), have been shown to form complexes with the nitric oxide synthase mutant 5114 [137]. Steady-state luminescence measurements with 13h establish a dissociation constant of 100 nM, while 13h binds with a... 

Luminescence has been observed from a large number of later transition element complexes and a rich array of excited states have been observed. Related sections from CCC (1987) include Chapter 16.5 on Pt, Rh, and Ir complexes, 36.3 on Mo halide clusters, 43 on Re complexes, 45.4 on Ru polypyridyls, 46.4 on Os polypyridyls, 48.6 on Rh complexes, and sections of Chapter 52 on Pt complexes. Several recent reviews have been published on polynuclear complexes, the photophysics of gold complexes,and platinum diimine complexes. Many other more narrowly focused review articles have been published on transition metal complex luminescence a significant number are published in the journal Coordination Chemistry Reviews and some of these reviews are cited in this chapter. 

Another chapter examines recent work in the area of metal-organic complexes derived from palladium(II) and platinum(II) diimine-dithiolate complexes. Pilato (Qiap. S), who is a leader in the development of new luminescent complexes of this family, has pioneered their application to sensing oiganophosphates and oxygen. His chapter describes the synthesis of these complexes, provides a comprehensive overview of their photophysical properties, and gives some examples of their application to the development of solid-state sensors. 

Besides the platinum and palladium diphosphine systems, platinum polypyridine complexes have also attracted attention in recent years [130-162). Their changes in spectroscopic and luminescence properties brought about by Pt Pt and n-n interactions are of particular interest [138-142). For instance, the square planar platinum(ii) diimine complex [Pt(bpy)Cl2) exhibits polymorphic behavior and rich photophysical properties [142-144). These, together with the recent growing development of platinum alkynyl systems [98, 122, 125, 145-147), mainly due to the...
