   <abstract xml:lang="ru">
    <p>В ходе реакций ароматического нуклеофильного замещения и восстановления получены смеси 1-(2-NH2-4-CF3-фенил)-1H- и 2-(2-NH2-4-CF3-фенил)-2H-бензотриазола, содержащие 1- и 2-замещенные изомеры в различных соотношениях. Изучена интенсивность УФ абсорбции смесями данных аминосоединений. Все смеси аминопроизводных бензотриазола обладали абсорбцией в диапазонах 280-200 нм, 315-280 нм и 400-315 нм. С увеличением содержания в смеси 2-замещенного изомера способность поглощать UVA и UVB излучение усиливалась. &#13;
При преобладании в смеси 1 замещенного производного более интенсивно абсорбировались UVС лучи. Наиболее перспективной оказалась смесь, содержащая 1- и 2-замещенные изомеры в соотношении 1 : 0.49, которая обладала сплошной и значительной абсорбцией во всем изучаемом диапазоне УФ спектра. По результатам квантовохимических расчетов показано, что гипсохромный сдвиг максимумов поглощения в УФ-спектре 1-замещенного изомера обусловлен стерическими затруднениями, которые делают молекулу существенно неплоской и нарушают сопряжение между бензотриазольным и анилиновым фрагментами. Это приводит к увеличению энергетической щели между ВЗМО и НВМО и возрастанию энергии электронных переходов.</p>
