“…Other functional group bands are 1760 cm −1 (C=O, stretching) for 4-CH 3 CO 2 ; 3365 (N-H, stretching), 1600 (C=O, stretching), 1554 (C-N in plane bending) for 4-CH 3 CONH. These bands were found also in copolymers of 2-phenyl-1,1-dicyanoethylene with vinyl acetate (15)(16)(17) and 4-fluorostyrene (18,19). 1 H-NMR spectra of the ST-TSE copolymers show a broad double peak in a 5.8-7.5 ppm region corresponding to phenyl ring protons.…”

We report the design, synthesis, molecular optical properties, and solid state emissive behaviour of a series of novel compounds, which, similar to the archetypal AIE luminogen tetraphenylethene, are formed of a central olefin stator and decorated with either three or four rotors. These rotors, being either electron-rich substituted benzenes, or electron-withdrawing functional groups (esters, ketones, cyano groups) confer a "push-pull" character to the overall molecular structure. Building on both new and already published contributions, a comprehensive picture of the properties and the potential of these compounds is provided.

“…The crystalline product of the reaction was isolated by filtration and purified by crystallization from 2-propanol. The details of the synthesis and characterization of 4-C 6 H 5 O, 2-C 6 H 5 CH 2 O-3-CH 3 O, 3-C 6 H 5 CH 2 O-4-CH 3 O, 4-Cl-3-NO 2 , 5-Cl-2-NO 2 substituted 2-phenyl-1,1-dicyanoethylenes were previously reported (14,15). 2-C 6 H 5 CH 2 O, 3,4-(C 6 H 5 CH 2 O) 2 , 2-C 6 H 5 CH 2 O-3-CH 3 O, 3-C 6 H 5 CH 2 O-4-CH 3 O-phenyl substituted 1,1-dicyanoethylenes were prepared and characterized.…”

and 4-fluorostyrene were prepared at equimolar monomer feed composition by solution copolymerization in the presence of a radical initiator (ABCN) at 70 • C. The composition of the copolymers was calculated from nitrogen analysis, and the structures were analyzed by IR, 1 H and 13 C-NMR. The order of relative reactivity (1/r 1 ) for the monomers is 3,4-(C 6 H 5 CH 2 O) 2 (31.0) > 2-). High T g of the copolymers, in comparison with that of poly(4-fluorostyrene) indicates a substantial decrease in chain mobility of the copolymer due to the high dipolar character of the trisubstituted ethylene monomer unit. Decomposition of the copolymers in nitrogen occurred in two steps, first in the 270-400 • C range with residue, which then decomposition in 400-800 • C range.
