Abstract

Here we report gas-phase action and luminescence spectra of cationic dyes derived from oxazine: cresyl violet (CV+), oxazine 170 (Ox-170+), nile blue (NB+), darrow red (DR+), oxazine 1 (Ox-1+), oxazine 4 (Ox-4+), and brilliant cresyl blue (BCB+). The first four have a benzofused structure, which results in asymmetric charge distributions along the long axis. The positive charge is also asymmetrically distributed in BCB+ while Ox-1+ and Ox-4+ are symmetric. As the ions are isolated in vacuo, there are no interactions with solvent molecules or counter ions, and the effect of chemical modifications is therefore more easily revealed than from solution-phase experiments. The transition energy decreases in the order: DR+ > CV+ > Ox-4+ > Ox-170+ > BCB+ > Ox-1+ > NB+, and the fluorescence from BCB+ is less than from the others. We discuss the results based on electron delocalisation, degree of charge-transfer character, rigidity of the chromophore structure, and substituents.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
