2,6-diaminopyridine derivatives as models of molecular sensor for nucleic acid base detection: ab initio calculations of electronic effects induced by hydrogen bonds formation.

Abstract

The performance of a molecular sensor for detecting nucleic acid base was studied by molecular orbital calculations of model compounds. The model compounds consist of a detecting unit (pyridine derivative), a conducting unit (benzene) and a connection between them. The changes of the HOMO, LUMO energy levels and charge distributions of the conducting unit… (More)
