Journal ArticleDOI
Absolute Measurements of Photoluminescence Quantum Yields of Solutions Using an Integrating Sphere
TL;DR: It is demonstrated that absolute measurements of the photoluminescence quantum yield of solutions can be made using an integrating sphere and a conventional fluorimeter, with the need for measurements against a luminescence standard overcome.
Journal ArticleDOI
Measurements of Solid‐State Photoluminescence Quantum Yields of Films Using a Fluorimeter
TL;DR: In this paper, a commercial spectrofluorimeter can be used successfully in combination with an integrating sphere to measure solid-state photoluminescence quantum yields of films.
Journal ArticleDOI
Experimental and Theoretical Studies of the Photophysical Properties of 2- and 2,7-Functionalized Pyrene Derivatives
Andrew G. Crawford,Austin D. Dwyer,Zhiqiang Liu,Zhiqiang Liu,Andreas Steffen,Andrew Beeby,Lars-Olof Pålsson,David J. Tozer,Todd B. Marder +8 more
TL;DR: The existence of a nodal plane passing through the 2- and 7-positions, perpendicular to the molecular plane in the HOMO and LUMO of pyrene, largely accounts for the different behavior of derivatives substituted at the 2,7-position.
Journal ArticleDOI
The Synthesis and One‐ and Two‐Photon Optical Properties of Dipolar, Quadrupolar and Octupolar Donor–Acceptor Molecules Containing Dimesitylboryl Groups
Jonathan C. Collings,Suk Yue Poon,Céline Le Droumaguet,Marina Charlot,Claudine Katan,Lars-Olof Pålsson,Andrew Beeby,Jackie A. Mosely,Hanns Martin Kaiser,Hanns Martin Kaiser,Dieter E. Kaufmann,Wai Yeung Wong,Mireille Blanchard-Desce,Todd B. Marder +13 more
TL;DR: Of these systems, the octupolar compound tris(E-4-dimesitylborylethenylphenyl)amine has been shown to exhibit the largest TPA cross-section among the two series of approximately 1000 GM at 740 nm, and make these systems attractive for applications involving two-photon excited fluorescence (TPEF).
Journal ArticleDOI
Energy Transfer and Charge Separation in Photosystem I: P700 Oxidation Upon Selective Excitation of the Long-Wavelength Antenna Chlorophylls of Synechococcus elongatus
Lars-Olof Pålsson,Cornelia Flemming,B. Gobets,Rienk van Grondelle,Jan P. Dekker,Eberhard Schlodder +5 more
TL;DR: It is concluded that at 5 K the excited state is not equilibrated over the antenna before charge separation occurs, and that approximately 50% of the excitations reach P700 before they become irreversibly trapped on one of the long-wavelength antenna pigments.
