Singlet Fission in Push–Pull Para‐Azaquinodimethane Films under the Gaze of Time Resolved Optical and Magnetic Spectroscopy

open access: yesAngewandte Chemie, Volume 138, Issue 6, 2 February 2026.
New push–pull para‐azaquinodimethane derivatives were synthetized through a sustainable protocol. Transient absorption results showed ultrafast intermolecular singlet fission (SF) in film and demonstrated for AsOMe higher triplet energy than for literature SF materials, with intriguing perspectives for photovoltaics toward silicon matched SF.

Hybridized quadrupole-dipole exciton effects in $Cu_2O$ - Organic Heterostructure

open access: yes, 2007
In the present work we discuss resonant hybridization of the $1S$ quadrupole Wannier-Mott exciton (WE) in a $Cu_2O$ quantum well with the Frenkel (FE) dipole exciton in an adjacent layer of organic DCM2:CA:PA.

Preferential solvation of p - nitrophenol in binary solvent mixtures [PDF]

open access: yes, 2011
The solvatochromism of p-nitrophenol (PNP) in different neat solvent and in binary mixtures of butanol and dioxane has been investigated from the spectroscopic transition energy (TE).
