Photoemission from Organic Molecular Solids and Organometallic Compounds

Recently several spectroscopic techniques have been newly developed for probing the electronic structure of organic molecules, molecular crystals and surfaces over large binding and excitation energy ranges. We discuss recent photoemission experiments from organic molecular crystals, organometallic compounds (metal-phthalocyanines) and metal-organic interfaces with emphasis on the important extensions of the photoemission technique made possible by using synchrotron radiation. Experimental aspects such as sample preparation, characterization, sample charging and decharging by a second light source (laser) as well as experimental aspects of C1 s and N1 s core level spectroscopy will also be briefly considered.
