Abstract
Four coumarin and phenanthridine-fused heterocycles were efficiently synthesized using base-mediated annulation of N-alkylquinolinium iodide and coumarin as a key step. One compound is found to be sensitive to light and changes color upon UV irradiation; the others are sensitive to heat and possess negative thermochromic properties. A novel light- and heat-sensitive molecular skeleton is introduced.
