Photophysics of Molecules Containing Multiples of the Azulene Carbon Framework

Publication date: Available online 24 June 2019Source: Journal of Photochemistry and Photobiology C: Photochemistry ReviewsAuthor(s): Ronald P. SteerAbstractThe literature capturing the unusual electronic structure and photophysics of monomeric azulene and its simple derivatives is briefly reviewed. The principles established on the basis of this model are then used to understand the experimental and predicted spectroscopic and photophysical behaviour of organic compounds containing two or more of the azulene carbon framework. Biazulenes, terazulenes and multiazulenes, both linked and fused, are discussed. The possibilities of singlet exciton fission from the S2 states of some of these molecules and their aggregates are examined. Gaps in the existing experimental data are identified.Graphical abstract
