Abstract

In the past years a great effort has been put in the design and synthesis of stable processable materials with metallic or semi-conducting properties. In order to fully exploit the possibilities of a newly synthesized conducting material its structure-function relation needs to be unraveled. Using two specific examples, it will be shown that modern EPR can reveal interesting properties of conducting materials. A detailed analysis will be given of a series of novel soluble platinum compounds designed to mimic the Magnus salt characteristics: [PtL2][Pt(mnt)2] and [PtL2][Pt(dmit)2], where L represents 1,10-phenanthroline or 4,4-dimethyl-2,2′-dipyridyl, and mnt (dmit) denotes 1,2-dicyanoethylenedithiolate (1,3-dithiol-2-thione-4,5-dithiolate). The studied complexes have semiconductive properties and high thermal stability. Although chemical analysis predicted the compounds to be diamagnetic, cw EPR revealed the presence of a considerable amount of paramagnetic species in the compounds. On the basis of a cw EPR and HYSCORE study at X-band, the species could be fully identified and the relation to the conductivity properties of the samples will be discussed.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
