Synthesis of oligomeric silsesquioxanes functionalized with (β-carboxyl)ester groups and their use as modifiers of epoxy networks

Dell'Erba, Ignacio Esteban; Williams, Roberto Juan Jose (Pergamon-Elsevier Science Ltd, 2007-07-27)

A silsesquioxane functionalized with (β-carboxyl)ester groups was synthesized by reacting a silsesquioxane functionalized with secondary hydroxyls with a stoichiometric amount of an acid anhydride. The reaction could be ...

Synthesis and characterization of a nanostructured photoluminescent silsesquioxane containing urea and dodecyl groups that can be patterned on carbon films

Lin, Derong; Hu, Lijiang; You, Hong; Williams, Roberto Juan Jose (Elsevier, 2011-05-17)

A silsesquioxane was synthesized by the hydrolysis and polycondensation of (EtO)3-Si(CH2)3NHCONH(CH2)11CH3 in tetrahydrofuran (THF) employing formic acid as catalyst. The silsesquioxane self-assembled into nanorods due to ...

Copper(II)tetrasulphophthalocyanine entrapped in a propylpyridiniumsilsesquioxane polymer immobilized on a SiO2/Al2O3 surface: Use for electrochemical oxidation of ascorbic acid

Fujiwara, ST; Pessoa, CA; Gushikem, Y (Marcel Dekker IncNew YorkEUA, 2002)

Epoxy networks based on solutions of silsesquioxanes functionalized with 3-glycidoxypropyl groups in diglycidylether of bisphenol A (DGEBA)

Mauri, Adriana Noemi; Riccardi, Carmen Cristina; Williams, Roberto Juan Jose (Springer, 2001-10-20)

In previous publications we reported the synthesis and characterization of silsesquioxanes derived from the hydrolytic condensation of (3-glycidoxypropyl) trimethoxysilane (GPMS) using diglycidylether of bisphenol A (DGEBA) ...

N-propylpyridinium chloride silsesquioxane polymer film on graphite: electrochemical study of a hexacyanoferrate (II) ion immobilized electrode for oxidation of ascorbic acid

Alfaya, Rení V. S.; Gushikem, Yoshitaka; Alfaya, Antonio A. S. (Sociedade Brasileira de Química, 2000)

Light-induced healing in azobenzene bridged silsesquioxanes

Galante, Maria Jose; Zucchi, Ileana Alicia; Oyanguren, Patricia Angelica; Sáiz, Luciana María (Pergamon-Elsevier Science Ltd, 2019-08)

Intrinsic healable polymers are materials capable of repairing itself through its chemical nature, in order to improve stability and durability and to restore the lost functionalities or properties. In this study, azobenzene ...
