Journal ArticleDOI
Kinetics of Ion Transport in Perovskite Active Layers and Its Implications for Active Layer Stability.
Monojit Bag,Lawrence A. Renna,Ramesh Y. Adhikari,Supravat Karak,Feng Liu,Paul M. Lahti,Thomas P. Russell,Thomas P. Russell,Mark T. Tuominen,Dhandapani Venkataraman +9 more
TL;DR: It is postulated that in MAPbI3 the predominant mechanism of accelerated device degradation under sunlight involves thermally activated fast ion transport coupled with a lattice-expanding phase transition, both of which are facilitated by absorption of the infrared component of the solar spectrum.
BookDOI
Magnetic Properties of Organic Materials
TL;DR: In this article , an integrated approach to organic-based molecular magnetic materials is presented, based on the resonance-valence bond theory and magnetic properties of organic magnetism in condensed phases.
Journal ArticleDOI
Semiempirical study of electron exchange interaction in organic high-spin .pi.-systems. Classifying structural effects in organic magnetic molecules
Paul M. Lahti,Andrew S. Ichimura +1 more
TL;DR: In this paper, a semi-empirical AM1 molecular orbital plus configuration interaction model is applied to π-conjugated organic open-shell molecules in order to understand qualitatively the manner and degree to which they are spin-coupled by various electronic mechanisms.
Journal ArticleDOI
Poly(phenylenevinylene)-Attached Phenoxyl Radicals: Ferromagnetic Interaction through Planarized and π-Conjugated Skeletons
TL;DR: In this article, a long-range intramolecular through-bond ferromagnetic exchange interaction was realized between the pendant unpaired electrons for the o- and p-polyradicals, in accordance with theoretical predictions based on the molecular connectivity.
Journal ArticleDOI
A cobalt pyrenylnitronylnitroxide single-chain magnet with high coercivity and record blocking temperature.
Maria G. F. Vaz,Rafael A. Allão Cassaro,Rafael A. Allão Cassaro,Handan Akpinar,John A. Schlueter,Paul M. Lahti,Miguel A. Novak +6 more
TL;DR: The coordination of a [Co(hfac)2] moiety with a nitronylnitroxide radical linked to bulky, rigid pyrene (PyrNN) gives a helical 1:1 chain complex, in which both oxygen atoms of the radical NO(·) groups are bonded to Co(II) ions with strong antiferromagnetic exchange.
