n
, wherein, n is an integer greater than or equal to 4; each R
1
is an amine-functional siloxy group, a quaternary ammonium-functional siloxy group, or a texturizing moiety. At least one R

group may optionally be a quaternary ammonium-functional siloxy group. Compositions may be prepared from polymers and the silsesquioxane compounds.
Abstract Pure organic room-temperature phosphorescence (RTP) materials have been attracting much attention recently. Herein, we report a facile approach combining heavyatom effect and external solvent stimuli to realize RTP. N-Allylquinolinium bromide under 365 nm UV exhibited intense green RTP emission with response upon adding chloroform. This interesting phenomenon endowed N-allylquinolinium bromide
