Optical limiting properties of soluble fullerene derivatives for incorporation in sol–gel materials

Abstract: The optical limiting properties of fullerene derivatives containing silicon alkoxide functionalities are measured in toluene solution both at 532.0 and 652.0 nm and compare favourably with those of Ca.

“…The possibility to develop materials possessing the unique properties of C 60 motivated these studies. In particular C 60 has been incorporated into different kinds of organic or inorganic materials, such as polymers [138][139][140][141][142][143][144][145][146][147] dendrimers [148][149][150][151][152][153][154][155][156][157][158] sol-gel matrices [159][160][161][162] and nanospheres [163][164][165][166][167]. C 60 has been synthesized by many researchers and various characteristics have been studies.…”

“…A enorme utilização de alcóxidos de silício é retratada como precursora na obtenção de materiais híbridos envolvendo fulerenos 47,48 , assim como a utilização de TMOS e TEOS como aditivos para reforçar a estrutura de polímeros orgânicos 49,50 . Os materiais com propriedades ópticas 51,52 , condutoras 53 ou catalíticas [54][55][56] foram também sintetizados, baseando-se sempre no uso de alcóxidos de silício como precursores.…”
