Journal ArticleDOI
Ultrafast Excimer Formation and Solvent Controlled Symmetry Breaking Charge Separation in the Excitonically Coupled Subphthalocyanine Dimer
TL;DR: In this paper, the solvent polarity dependent excited state dynamics of the structurally well-defined subphthalocyanine dimer, μ•OSubPc 2, were investigated.
Journal ArticleDOI
Electronic Energy Transfer in a Subphthalocyanine-Zn Porphyrin Dimer Studied by Linear and Nonlinear Ultrafast Spectroscopy.
Giovanni Bressan,Andrew N. Cammidge,Garth A. Jones,Ismael A. Heisler,Daniel Gonzalez-Lucas,Sonia Remiro-Buenamañana,Stephen R. Meech +6 more
TL;DR: This work studies EET in a synthetic dyad comprising a visible absorbing subphthalocyanine donor and a Zn tetraphenyl porphyrin acceptor, and calculates the rate of the forward energy transfer in terms of the structure of the dimer, which is calculated by density functional theory.
Journal ArticleDOI
Ultrafast Excited State Dynamics in a First Generation Photomolecular Motor.
Andy S. Sardjan,Palas Roy,Wojciech Danowski,Giovanni Bressan,Laura Nunes Dos Santos Comprido,Wesley R. Browne,Ben L. Feringa,Stephen R. Meech +7 more
TL;DR: The primary photophysical processes in the archetypal first generation photomolecular motor are probed with sub‐50 fs time resolved fluorescence spectroscopy, finding a strong solvent friction effect which is ascribed to torsion about the C−C axle.
Journal ArticleDOI
One- to Two-Exciton Transitions in Perylene Bisimide Dimer Revealed by Two-Dimensional Electronic Spectroscopy.
Giovanni Bressan,Dale Green,Yohan Chan,Philip C. Bulman Page,Garth A. Jones,Stephen R. Meech,Ismael A. Heisler +6 more
TL;DR: Here, exciton transitions in two different covalently bound PBI dimers are studied by two-dimensional electronic spectroscopy (2DES), a powerful spectroscopic method, providing the most complete picture of vibronic transitions in molecular systems.
Journal ArticleDOI
Exciton–Exciton Annihilation as a Probe of Exciton Diffusion in Large Porphyrin Nanorings
TL;DR: The photophysical behavior of natural and artificial cyclic supramolecular structures has been intensively investigated in the past decade as discussed by the authors, including large fully π-conjugated structures.
