Photoactive thin films of terphenylene-based amorphous polymers. Synthesis, electrooptical properties, and role of photoquenching and inner filter effects in the chemosensing of nitroaromatics
Garay, Raúl O.,Del Rosso, Pablo G.,Romagnoli, Maria J.,Almassio, Marcela F.,Schvval, Ana Belén
, (2019)
New photoactive segmented conjugated polymers with terphenylene chromophores were synthesized, and the chemosensing abilities to detect nitroaromatics compounds (NACs) of the polymeric thin films were evaluated in aqueous media. The thin films are strongl

Paragraph 0042; 0043, (2015/11/09)
A method for the manufacture of a metal salt of a hydroxy-substituted aromatic compound comprises: contacting a hydroxy-substituted aromatic compound with a base comprising a metal cation in molten diphenyl sulfone or sulfolane to provide a mixture compri

Organotin oxide was used to catalyze the reaction between BPA (bisphenol A) and DMC (dimethyl carbonate), and Ph2SnO (diphenyltin oxide) displays the excellent catalytic performance in transesterification and O-methylation. However, Bu2SnO (dibutyltin oxide), (PhCH 2)2SnO (dibenzyltin oxide) and (C6H 11)2SnO (dicyclohexyltin oxide) exhibited weaker catalytic activity but higher selectivity for C-methylation product formation. The π-π function between Ph2SnO and BPA provided more chances for their interaction, and π-d interaction between phenyl ring and Sn resulted in catalyst having higher activity in transesterification and O-methylation. O-methylation product formation over Ph2SnO comes from transesterification product decomposition not from direct methylation of BPA with DMC.
