Twist-twist π-conjugated (TTPC) π systems promise unique properties with their 90° twist angles. Di-sec-alkyl substituted stilbenes, 5, were prepared by low-valent titanium coupling of phenyl ketones, 4. Long alkyl chains stopped the coupling reaction. Stilbenes 5 were shown to be ～90% TTPC. Inserting TTPC units into poly(p-phenylene) polymers created highly fluorescent, soluble, TTPC π systems with weak electronic segmentation for organic light emitting diode (OLED) studies.
