In this work, the authors investigate graphene nanoribbons of the «armchair» and «zigzag» types with different concentrations of pyrrole-like nitrogen at the edges. The SCC-DFTB method was used to establish the most energetically favorable configurations of pyrrole-like nitrogen at each edge of graphene nanoribbons. The relationship between the energy gaps of graphene nanoribbons and the content of the considered functional nitrogen-containing groups in them was determined. Calculations have shown that, by incorporating into the atomic lattice, pyrrole-like nitrogen at the «zigzag» edge transfers a greater amount of charge to nearby carbon atoms, which makes such nanoribbons more chemically active in comparison with «armchair» type nanoribbons. Nitrogen doped «zigzag» graphene nanoribbons may be a promising chemoresistive element of nanosensors; however, these conclusions require further calculations.</p></abstract><trans-abstract xml:lang="ru"><p>Допирование графеновых нанолент различными химическими элементами приводит к изменению их зонной структуры, что значительно расширяет спектр применения данных объектов в современных электронных устройствах. В настоящей работе исследованы графеновые наноленты с краем типа «кресло» и «зигзаг» с различной концентрацией пирролоподобного азота на краях. Методом функционала плотности в приближении сильной связи с применением самосогласованного заряда &amp;#40;Self-Consistent Charge Density Functional Tight-Binding, SCC-DFTB&amp;#41; установлены наиболее выгодные с энергетической точки зрения конфигурации пирролоподобного азота на каждом из краев графеновых нанолент. Определена зависимость между энергетическими щелями графеновых нанолент и содержанием в них функциональных азотосодержащих групп. Расчеты показали, что, встраиваясь в атомную решетку, пирролоподобный азот на краю графеновой наноленты типа «зигзаг» передает большее количество заряда находящимся рядом атомам углерода, что делает такие наноленты более химически активными по сравнению с графеновыми нанолентами с краем типа «кресло». Графеновые наноленты с краем типа «зигзаг», допированные азотом, могут являться перспективным хеморезистивным элементом наносенсоров, однако данные выводы требуют дальнейших расчетов.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>графеновые наноленты</kwd><kwd>пирролы</kwd><kwd>молекулярное моделирование</kwd><kwd>зонная структура</kwd><kwd>энергетическая щель</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена при финансовой поддержке  Минобрнауки России (проект № FSRR-2020-0004).</funding-statement></funding-group></article-meta>
