coupling reaction. The polymers exhibited absorption maxima at longer wavelength due to π-π* transition of the mainchain, which indicates the expansion of π-conjugated system along the polymermainchain. The polymers showed acid-base responsive fluorescence due to the lactone ring opening-closing property in the mainchain accompanied by the addition of alkali and acid. The polymers also exhibited ion

A series of novel π-conjugated polymers bearing alternating coumarin and phenylene units in the mainchain backbone was synthesized via Sonogashira coupling reaction. The red-shifts in the absorption maxima of the polymers indicate the expansion of π-conjugated system in the polymermainchains. These polymers exhibited strong green fluorescence in organic solvents. Clearly perceptible dual-color halochromic
