Abstract
The effect of benzo-annelations on the HOMO-LUMO energy gaps was examined in a series of benzo-derivatives of anthracene and acridine. It was shown that angular benzo-annelation increases the HOMO-LUMO gap value, while linear benzo-annelation decreases it compared to the non-annelated parent molecules. A simple quantitative model was developed being able to accurately predict the HOMO-LUMO gap values using only the numbers of angularly and linearly annelated benzene rings.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
