“…3 Thereafter, other chemiluminescence systems were reported, like the transition metals catalyzed oxidation of luminol (5-amino-2,3-dihydro-1,4-phtalazinedione, 2) by H 2 O 2 , described by Albrecht in 1928, 4 and the oxidation of lucigenin (N,N'-dimethyl-9,9'-bisacridinium salt, 3) described by Gleu and Petsch. 5 In a general way, any chemiluminescent transformation involves the formation of electronically excited states from an exothermic reaction, in one or more steps. Obviously not every exothermic reaction leads to formation of excited states, because in a conventional thermal reaction the energy is used to form or cleave bonds between the atomic centers involved; the energy is utilized to promote the reagent to the transition state level which forms the product in a vibrationally excited state, which decays to the vibrational ground state with emission of thermal energy in the form of heat.…”

“…4 e a reação quimiluminescente da lucigenina (N,N'-dimetil-9,9'-biacridina, 3) reportada por Gleu e Pestch. 5 Somente em 1963 um dos atualmente mais importantes sistemas quimiluminescentes seria descrito por Chandross: a reação de cloreto de oxalila com H 2 O 2 , na presença de 9, 10 -difenilantraceno, produzindo uma intensa luz azulada. 6 Tal reação, batizada pelo autor de sistema peróxi-oxalato, foi subsequentemente estudada por Rauhut 7 que, juntamente com seu grupo, contribuiu no sentido de definir diversos aspectos mecanísticos acerca de tal transformação, bem como estabeleceu conceitos atualmente considerados fundamentais em quimiluminescência orgânica.…”

“…Sequência CIEEL simplificada para a quimiexcitação de um ACT, pela interação do mesmo com uma 1,2-dioxetanona (5) Para este processo de decomposição catalisada de peróxidos, que também pode ser classificado como quimiluminescência ativada, mesmo antes de ter se definido o mecanismo CIEEL, haviam sido obtidas evidências do envolvimento de uma transferência de elétron no passo de quimiexcitação do chamado sistema peróxi-oxalato. 7 Tais evidências foram confirmadas subsequentemente através do estudo da decomposição catalisada de 1,2-dioxetanonas isoláveis, onde se observou uma transferência de elétron do ACT para o peróxido ou, no mínimo, uma transferência de carga.…”

“…Lucigenin (10,10'-dimethyl-9,9'-biascridinium nitrate) is one of the more efficient CL substances which emits an intense green emission when oxidised in an alkaline medium [40]. Other acridinium derivatives have been shown to produce CL emission upon hydrogen peroxide oxidation of aqueous alkaline solutions.…”
