Linha de Pesquisa: LABORATÓRIO DE FOTODINÂMICA MOLECULAR/MOLECULAR PHOTO DYNAMICS

 Resumo

O laboratório desenvolve estudos nas áreas de fotoquímica e fotofísica de moléculas orgânicas, em particular de corantes naturais (antocianinas); estrutura e dinâmica de sistemas organizados formados por detergentes e polieletrólitos e a modificação de reatividade química e fotoquímica por esses sistemas; e química ambiental (mecanismos de reações de degradação e foto-degradação de moléculas orgânicas).

O laboratório conta com equipamentos especializados para o estudo da dinâmica de estados eletronicamente excitados (fluorescência estática e resolvida no tempo; fotólise por pulso de laser).

 

Summary

The laboratory conducts studies in the areas of photochemistry and photophysics of organic molecules, in particular of natural plant pigments (anthocyanins); the structure and dynamics of organized systems formed by detergents and polyelectrolytes and the modification of chemical and photochemical reactivity by such systems; and environmental chemistry (mechanisms of degradation and photodegradation reactions of organic molecules). 

The laboratory has specialized equipment for the study of the dynamics of electronically excited states (static and time-resolved fluorescence, nanosecond laser flash photolysis.
