- Разработка новых функционализированных органических соединений, способных эффективно координировать ионы металлов, остается актуальной задачей при создании химических сенсоров для мониторинга состояния окружающей среды. В данной работе продемонстрировано значительное снижение предела обнаружения ионов Cd за счет использования производного 6-формильзамещенного спироиндолинбензопирана, содержащего бензоксазольный фрагмент в положении 8´ бензопиранового кольца. Введение молекул спиропирана в матрицу на основе силоксан-акрилатного латекса и их ассоциация с тетрафенилборат-ионом, выполняющим роль спейсера и препятствующим π-стэкингу и самотушению люминесценции, позволили значительно повысить чувствительность сенсорного материала. Использование прозрачных, ионопроницаемых латексных пленок, модифицированных комплексами СП-ТФБ, обеспечило снижение предела обнаружения Cd на пять порядков – до 1,66 нМ.
