Abordagens sintéticas para a funcionalização de novas porfirinas
(Universidade Federal de São Carlos, 2016-09-30)
Herein, we optimized some conditions in the synthesis of a β-octasubstitued porphyrin with electron withdrawing groups (1). This system was used to study the bromination of the meso position aiming at subsequent ...
Estudo da formação e isolamento de heterocomplexos constituídos pela combinação entre 4,4’,4’’,4’’’- tetracarboxiftalocianina de ferro ou 4,4’,4’’,4’’’- tetrassulfoftalocianina de ferro e tetrakis (N-metil- 4-piridil) porfirina de ferro e aplicação em filmes LbL”
(Universidade Federal de São Carlos, 2016-01-04)
The great
interest in supramolecular assemblies between porphyrins and phthalocyanines has
growing lately due to the enhancement on chemical and physical properties compared to
individual units. Ionic assemblies with ...
Compostos carbonílicos heterobimetálicos de Ru(II)/Fe(II) : propriedades citotóxicas e estudo da interação com BSA e DNA
(Universidade Federal de São Carlos, 2016-03-30)
Ruthenium and iron-based drugs are an option for the development of improved chemotherapeutic agents for cancer treatment with lower toxicity. Thereby, this work present the in vitro cytotoxic activity and in vitro interaction ...
Síntese e caracterização de heteropentâmeros formados por cobaltoftalocianina e cobaltotetrafenilporfirina
(Universidade Federal de São Carlos, 2012-02-29)
Metalloporphyrins and metalophthalocyanines assemblies have attracted in the last few decades. The syntheses of face to face systems containing porphyrins or phthalocyanines can found in literature, however few works ...
Sensores nanoestruturados compostos por nanofibras de dióxido de titânio modificadas com polímeros condutores visando monitoramento de compostos orgânicos voláteis
(Universidade Federal de São Carlos, 2020-03-18)
The growth of urbanization and anthropogenic activities have been increasing the emission of polluting gases in the atmosphere. Considering the high toxicity of some of these gases, it becomes necessary to develop new ...
