Jung, Eun Ae published the artcileSynthesis and photoelectronic properties of thermally stable poly[oxy(2,7-fluoren-9-onenylene)oxy(diorganosilylene)]s, HPLC of Formula: 14799-93-0, the publication is Bulletin of the Korean Chemical Society (2012), 33(6), 2031-2036, database is CAplus.
Melt copolymerization reactions of several bis(diethylamino)silane derivatives, bis(diethylamino)methylphenylsilane, bis(diethylamino)methyloctylsilane, 1,2-bis(diethylamino)tetramethyldisilane, and 1,3-bis(diethylamino)tetramethyldisiloxane, with 2,7-dihydroxyfluoren-9-one were carried out to yield poly[oxy(2,7-fluoren-9-onenylene)oxy(diorganosilylene)]s bearing the fluoren-9-one fluorescent aromatic group in the polymer main chain: poly[oxy(2,7-fluoren-9-onenylene)oxy(methylphenylsilylene)], poly[oxy(2,7-fluoren-9-onenylene)oxy(methyloctylsilylene)], poly[oxy(2,7-fluoren-9-onenylene)oxy(tetramethyldisilylene)], and poly[oxy(2,7-fluoren-9-onenylene)oxy(tetramethyldisiloxanylene)]. These polymeric materials are soluble in common organic solvents such as CHCl3 and THF. FTIR spectra of all the materials reveal characteristic Si-O-C stretching frequencies at 1012-1018 cm-1. In the THF solution, the prepared materials show strong maximum absorption peaks at 258-270 nm, strong maximum excitation peaks at 260-280 nm, and strong maximum fluorescence emission bands at 310-420 nm. TGA thermograms suggest that most of the polymers are essentially stable to 200° without any weight loss and up to 300° with only a weight loss of less than 5% in nitrogen.
