摘要: Novel polyfluorene copolymers with pendant hydroxyl groups, poly[2,7-(9,9-dihexylfluorenel-2,7-(9,9-bis(6-hydroxyhexyl)-fluorene)-co-2,7-(9,9-dihexylfluorene)-1,4-phenylene] (PFP-OH) and poly[2,7-(9,9-dihexylfluorene)-2,7-(9,9-bis/6-hydroxyhexyl)fluorene)-co-2,7-(9,9-dihexylfluorene)-4,7-(2,1,3-benzothiadiazole)] (PFBT-OH) were prepared. Acid-catalyzed polycondensations of tetraethoxysilane carried out in the presence these polymers to obtain homogeneous hybrids. Photoluminescence spectra hybrids suggested immobilized silica matrix retaining their π-conjugated structures. Further, coat film prepared utilizing perhydropolysilazane as a precursor. Their optical properties examined.
